Page 11 of 34 2019-06-12 2019 Copyright by Acconeer A111 Pulsed Coherent Radar (PCR) Datasheet, v1.8 5 Timing Requirements 5.1 Serial Peripheral Interface The Serial Peripheral Interface (SPI) is a 4-wire serial bus, used for configuration and reading output from the A111 radar sensor. The A111 radar sensor is an SPI slave device connected to the SPI master, as described in figure 5.1. The A111 allows several devices to be connected on the same SPI bus, with a dedicated slave-select signal. Daisy-chain is not supported. Figure 5.1. SPI master-slave connection The serial data transfer input (MOSI) and output (MISO) to the A111 are synchronized by the SPI_CLK. The Slave Select signal (SS) must be low before and during transactions. The MOSI is always read on the rising edge of SCLK and the MISO changes value on the falling edge of SPI_CLK
(SPI mode 0, CPOL/CPHA = 0). SS requires release in between transactions. See figure 5.2 and table 5.1 for timing characteristics.

Figure 7.1. System integration The Acconeer software is executed on Host MCU that handles sensor initiation, configuration, sweep acquisition and signal processing. The Serial Peripheral Interface (SPI) is a 4-wire serial bus, used for configuration and reading output from the A111 radar sensor. The A111 radar sensor is an SPI slave device, connected to the SPI master (Host MCU), and allows several devices to be connected on same SPI bus, with a dedicated slave-select signal. Daisy-chain is not supported. The sensor provides support for ENABLE and INTERRUPT as interrupt signal, always output, that is used as an interrupt in the Host MCU.

The Acconeer software is executed on Host MCU and delivered as binaries, except for integration software that is delivered as source code. The below figure shows the A111 software offer. Figure 7.2. Acconeer Software offer The RSS (Radar System Software) provides output at two different levels, Service and Detector. RSS provides an API (Application Programming Interface) for Application utilization of various Services and Detectors. The Service output is pre-processed sensor data as a function of distance E.g. Envelope data
(amplitude of sensor data), Power bin data (integrated amplitude data in pre-defined range intervals), IQ modulated data (representation in cartesian) etc. Detectors are built on Service data as input and the output is a result E.g. Distance detector that presents distance and amplitude result based on envelope Service etc. Customer can either use Acconeer detector or develop their own signal processing based on Service data. Acconeer provides several example applications to support customer own application development. Also, customer guidelines are provided for application development utilizing the Acconeer RSS API. Acconeer provides several reference drivers as source code, e.g. Support for Cortex M4, Cortex M7 MCUs. 7.2 Software Integration Integration software shall implement functions defined in a definitions file provided in Acconeer Software offer. This includes handling of SPI, ENABLE and INTERRUPT as well as potential OS functions. See reference HAL - User Guide for guideline on software integration and HAL implementation
(https://www.acconeer.com/products). 2019 Copyright by Acconeer 2019-06-12 Page 18 of 34 A111 Pulsed Coherent Radar (PCR) Datasheet, v1.8 7.3 Power Up Sequence The power-up sequence is described using the recommended integration shown in the below figure:
Figure 7.3. Recommended integration of the A111 radar sensor. The power up sequence is shown in below figure. Figure 7.4. Power up sequence Page 19 of 34 2019-06-12 2019 Copyright by Acconeer A111INTERRUPTSPI_SSSPI_MISOSPI_MOSISPI_CLKENABLEVIO_1a,bVIO_2a,bVIO_3a,bVBIASXINXOUTGNDsR11.8VX1C8C7R2C4C1C5C2C6C3HostTimeVIO_1-3a,bENABLEt1t2XIN A111 Pulsed Coherent Radar (PCR) Datasheet, v1.8 It is recommended to allow the supply voltage on the sensor to stabilize before activating ENABLE. That is shown as the time t1 in figure 7.4 and the actual time depends on the power supply and the value of the decoupling capacitors. Next step in the power up sequence is to have a settling time for the XTAL oscillator to stabilize, shown as time t2 in figure 7.4. This may take up to several milliseconds depending on the XTAL performance. The sensor does not require any settling time if it is integrated using an external reference clock. It is advised to have the clock inactive at 0 V while ENABLE is inactive. Now the A111 radar sensor is ready for SPI communication. All I/Os must never exceed VIO_3 voltage, accordingly if VIO_3 voltage is set to 0V between sensor usage then all I/Os must also be set to 0V. Otherwise, the internal ESD protection diodes will draw current from the I/O source. After power up is complete, the sensor is loaded with a program. Up until the point where the sensors program is started, the INTERRUPT is high impedance. However, after the sensors program has started the INTERRUPT is configured to a push-pull CMOS output. Therefore it is required that the host I/O is configured as input before any programs are started on the sensor. The power down sequence is recommended to be executed in the reverse order as the power up sequence: First ensure that all I/O inputs are at 0V which includes ENABLE, after that all VIO1_3a,b can be turned off. VIO_1 and VIO_2 must never have higher voltage than VIO_3, and it is recommended to enable/disable the three supplies simultaneously. External clock reference, if used, needs always to be available to sensor. 2019 Copyright by Acconeer 2019-06-12 Page 20 of 34 A111 Pulsed Coherent Radar (PCR) Datasheet, v1.8 8 Layout Recommendations A111 sensor free space integration should take the following into consideration:
Any material above the sensor should have as low permittivity and loss as possible, e.g. plastic or glass with low permittivity. To conclude on optimum distance from the sensor, a simulation/measurement investigation is required. The sensor antennas are of a folded dipole type, with its ground reference in the package ground plane, extending over the whole area of the sensor. To further enhance the directivity of the sensor, the package ground plane should be extended to the package by soldering all GND connections of the sensor to the board top layer ground. This top layer ground plane below the sensor should be continuous and should have low impedance. The below table shows the sensor gain loss versus solid ground plane area. Ground plane area Sensor gain loss 625 mm2 425 mm2 225 mm2 127 mm2 29 mm2 0 dB
-0.2 dB
-0.4 dB
-2.2 dB
-4.0 dB Table 8.1 Simulated relative maximum gain as function of extended solid ground plane area. The area is quadratic. It is recommended to keep the layout around XIN and XOUT symmetrical to the XTAL and capacitors.

The A111 sensor has a built-in XTAL oscillator and by adding an external XTAL component, as shown in the below figure 8.1, a reference design without any external clock reference supplied is possible. Note however, that the external clock reference still is supported and if used instead of an external XTAL, it is connected to XIN. Figure 8.1. External XTAL schematics. To enable the internal XTAL oscillator to drive the external resonator, the relation in equation 1 must be fulfilled. Equation 1 0.8 0.61 < 0.7 Equation 2
= 2( ) Equation 3
= + 2 The capacitance values are calculated in equation 2. CL and RESR are XTAL parameters and vary from XTAL to XTAL. The stray capacitance is the sum of the capacitance between XIN and XOUT, which are found in the traces on PCB and in the package; 2 to 5 pF is a general estimation. Example:
f = 26 MHz CL = 9 pF RESR = 40 ohm Assuming that Cstray = 5 pF gives C7, C8 = 8 pF and that the condition is met with the result 0.63 <

The values of the component demonstrate an example filter design, exact values depend on switching frequency and ripple amplitude of the supply regulator. However, be aware of LC filter peaking at the series resonance frequency 1/(2*sqrt(LC)). A small resistor, 250 m in the example filter, can be inserted to lower the Q factor of the filter. In certain applications, where disturbances at the series resonance frequency is present, the filter may not be an optimal solution and an external LDO such as TPS7A8801 or equal is recommended to use instead of the low-cost LC filter.

The A111 radar sensor is an SPI slave device connected to the SPI master, as described in figure 5.1. The A111 allows several devices to be connected on the same SPI bus, with a dedicated slave-select signal. Daisy-chain is not supported. Figure 5.1. SPI master-slave connection The serial data transfer input (MOSI) and output (MISO) to the A111 are synchronized by the SPI_CLK. The Slave Select signal (SS) must be low before and during transactions. The MOSI is always read on the rising edge of SCLK and the MISO changes value on the falling edge of SPI_CLK
(SPI mode 0, CPOL/CPHA = 0). SS requires release in between transactions. See figure 5.2 and table 5.1 for timing characteristics.

Figure 7.1. System integration The Acconeer software is executed on Host MCU that handles sensor initiation, configuration, sweep acquisition and signal processing. The Serial Peripheral Interface (SPI) is a 4-wire serial bus, used for configuration and reading output from the A111 radar sensor. The A111 radar sensor is an SPI slave device, connected to the SPI master (Host MCU), and allows several devices to be connected on same SPI bus, with a dedicated slave-select signal. Daisy-chain is not supported. The sensor provides support for ENABLE and INTERRUPT as interrupt signal, always output, that can be used as an interrupt in the Host MCU.

The Acconeer software is executed on Host MCU and delivered as binaries, except for driver software that is delivered as source code. The Acconeer software also provides example applications as reference source code for utilizing various Acconeer Services and Detectors, to facilitate customer software development on application level. Acconeer Services provides data and Acconeer Detectors provides result based on Service data. The below figure shows the A111 software architecture:
Note: The green boxes are binaries and the yellow boxes are delivered as source code. Figure 7.2. SW architecture The Application layer addresses functional requests for various provided services using an Acconeer defined API (Application Programming Interface). Acconeer provides several example applications, that are service oriented. Also, customer guidelines are provided for application development utilizing the Acconeer API. The Service layer handles functional requests on services and returns service data per request. The service data can be either processed by application itself or pushed from the application toward a specific detector to generate calculated result e.g. distance, amplitude. The Session layer, depending on given service, creates dedicated sessions for one or multiple sensors. Note that multiple sensors are supported and handled from a single host, where the Acconeer software is running. A session is implemented by a request handler(s), handling sensor initiation, configuration, sweep acquisition and signal processing. Results are available through callback function or blocking function call. The Sensor layer handles the sensor control and communication functions. Core function handles different sweep configurations, set in the API. The HAL layer (Hardware Abstraction Layer) handles integration towards customer hardware, e.g. driver registration and pin mapping toward SPI and INTERRUPT. Acconeer provides several reference drivers as source code, e.g. Support for Cortex M4, Cortex M7 MCUs. 2018 Copyright by Acconeer 2019-02-13 Page 18 of 32 Hardware Abstraction Layer, HALSensor LayerSession LayerSensor DriverService LayerService ARequest Handler XService BService CRequest Handler YCoreSPI driverGPIO driverSPI deviceGPIO deviceDetectorsDetector Detector Detector Application LayerExample Application IExample Application IIExample Application IIIBoard A111 Pulsed Coherent Radar (PCR) Datasheet, v1.5.2 Acconeer also provides detectors, such as a distance detector where the application can push service data to retrieve data result. 7.2 Devices and Drivers The driver for SPI and INTERRUPT shall implement the defined functions found in the corresponding device header file, acc_device_spi.h and acc_device_gpio.h. Registration of these functions shall be done in the acc_board_init function, see chapter 7.3 for details. 7.3 Board File Interface and Implementation The board header file, acc_board.h is the board file interface. Contents may not be changed, implementation needed for all functions and parameters in the file. NOTE, an implementation may in some cases be empty. A detailed description of each board file function is shown in the table below. acc_board function Description acc_board_init acc_board_gpio_init acc_board_start_sensor acc_board_stop_sensor acc_board_get_spi_bus_cs acc_board_chip_select acc_board_is_sensor_interrupt_connected Init Register driver: SPI mandatory Initiation of GPIO. o Mandatory pin for sensor operation is ENABLE Start a sensor Fulfill power up sequence Stop a sensor Fulfill power down sequence Get SPI bus number and chip select pin(s) Custom chip select logic, empty implementation allowed Get interrupt connection status acc_board_is_sensor_interrupt_active Get interrupt status acc_board_get_sensor_count acc_board_get_ref_freq acc_board_get_spi_speed acc_board_set_ref_freq Table 7.1.

Figure 7.3. Recommended integration of the A111 radar sensor. The power up sequence is shown in below figure. Figure 7.4. Power up sequence 2018 Copyright by Acconeer 2019-02-13 Page 20 of 32 A111INTERRUPTSPI_SSSPI_MISOSPI_MOSISPI_CLKENABLEVIO_1a,bVIO_2a,bVIO_3a,bVBIASXINXOUTGNDsR11.8VX1C8C7R2C4C1C5C2C6C3HostTimeVIO_1-3a,bENABLESPI_SSt1t2XIN A111 Pulsed Coherent Radar (PCR) Datasheet, v1.5.2 It is recommended to allow the supply voltage on the sensor to stabilize before activating ENABLE. That is shown as the time t1 in figure 7.4 and the actual time depends on the power supply and the value of the decoupling capacitors. Next step in the power up sequence is to have a settling time for the XTAL oscillator to stabilize, shown as time t2 in figure 7.4. This may take up to several milliseconds depending on the XTAL performance. The sensor does not require any settling time if it is integrated using an external reference clock. It is advised to have the clock inactive at 0 V while ENABLE is inactive. Now the A111 radar sensor is ready for SPI communication. All I/Os must never exceed VIO_3 voltage. After power up is complete, the sensor is loaded with a program. Up until the point where the sensors program is started, the INTERRUPT pin is high impedance. However, after the sensors program has started the INTERRUPT pin is configured to a push-pull CMOS output. Therefore it is required that the host I/O is configured as input before any programs are started on the sensor. The power down sequence is recommended to be executed in the reverse order as the power up sequence: First ensure that all I/O inputs are at 0V which includes ENABLE, after that all VIO1_3a,b can be turned off. VIO_1 and VIO_2 must never have higher voltage than VIO_3, and it is recommended to enable/disable the three supplies simultaneously. External clock reference, if used, needs always to be available to sensor. Page 21 of 32 2019-02-13 2018 Copyright by Acconeer A111 Pulsed Coherent Radar (PCR) Datasheet, v1.5.2 8 Layout Recommendations A111 sensor free space integration should take the following into consideration:
Any material above the sensor should have as low permittivity and loss as possible, e.g. plastic or glass with low permittivity. To conclude on optimum distance from the sensor, a simulation/measurement investigation is required. The sensor antennas are of a folded dipole type, with its ground reference in the package ground plane, extending over the whole area of the sensor. To further enhance the directivity of the sensor, the package ground plane should be extended to the package by soldering all GND pins of the sensor to the board top layer ground. This top layer ground plane below the sensor should be continuous and should have low impedance. The below table shows the sensor gain loss versus solid ground plane area. Ground plane area Sensor gain loss 625 mm2 425 mm2 225 mm2 127 mm2 29 mm2 0 dB
-0.2 dB
-0.4 dB
-2.2 dB
-4.0 dB Table 8.1 Simulated relative maximum gain as function of extended solid ground plane area. The area is quadratic. It is recommended to keep the layout around XIN and XOUT symmetrical to the XTAL and capacitors. VIO_1a and VIO_1b are short circuit inside the sensor and are recommended to be connected to each other on the PCB as well. VIO_2a and VIO_2b are short circuit inside the sensor and are recommended to be connected to each other on the PCB as well. VIO_3a and VIO_3b are short circuit inside the sensor and are recommended to be connected to each other on the PCB as well. It is recommended to have decoupling capacitors on the supplies placed as close as possible to the supply terminals. It is recommended as minimum 100 nF in parallel with 1 uF decoupling capacitance on each supply. 2018 Copyright by Acconeer 2019-02-13 Page 22 of 32 A111 Pulsed Coherent Radar (PCR) Datasheet, v1.5.2 The below table shows BOM for integration of the A111:

Page 23 of 32 2019-02-13 2018 Copyright by Acconeer A111 Pulsed Coherent Radar (PCR) Datasheet, v1.5.2 8.1 XTAL The input clock can origin from a crystal (XTAL), connected to XIN and XOUT. The A111 sensor has a built-in XTAL oscillator and by adding an external XTAL component, as shown the below figure 8.1, a reference design without any external clock reference supplied is possible. Note however, that the external clock reference still is supported and if used instead of an external XTAL, it is connected to XIN pin. Figure 8.1. External XTAL schematics. To enable the internal XTAL oscillator to drive the external resonator, the relation in equation 1 must be fulfilled. Equation 1 0.8 0.61 < 0.7 Equation 2

= + 2 The capacitance values are calculated in equation 2. CL and RESR are XTAL parameters and vary from XTAL to XTAL. The stray capacitance is the sum of the capacitance between XIN and XOUT, which are found in the traces on PCB and in the package; 2 to 5 pF is a general estimation. Example:
f = 26 MHz CL = 9 pF RESR = 40 ohm Assuming that Cstray = 5 pF gives C7, C8 = 8 pF and that the condition is met with the result 0.63 <
