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 5.2: Timing diagram of SPI, CPOL=0 and CPHA=0. 2019 Copyright by Acconeer 2019-11-01 Page 12 of 33 Host

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. 2019 Copyright by Acconeer 2019-11-01 Page 14 of 33 Host MCU SPI x4 ENABLE x1 INTERRUPT x1 A111 Sensor 1.8V single power supply TCXO CLK ref. 20-80 MHz A111 Pulsed Coherent Radar (PCR) Datasheet, v2.0 prel. 6.1 Acconeer Software The Acconeer software has been written in C and is portable to any OS and HW platform. 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. 6.2 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

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 2019 Copyright by Acconeer 2019-11-01 Page 16 of 33 R2 R1 INTERRUPT A111 SPI_SS SPI_MISO SPI_MOSI SPI_CLK ENABLE 1.8V VIO_1a,b VIO_2a,b VIO_3a,b VBIAS XIN XOUT Host C4 C1 C5 C2 C6 C3 s D N G X1 C7 C8 t1 t2 VIO_3a,b VIO_1-2a,b ENABLE XIN Time A111 Pulsed Coherent Radar (PCR) Datasheet, v2.0 prel. VIO_3a,b must be turned on before or simultaneously with ENABLE and VIO_1-2a,b. ENABLE and VIO_1-2a,b can be turned on in any order and independently of each other. A111 should however not be considered as in state ON until all supply voltage levels are stable and ENABLE is high. The time constant t1 in figure 7.4 denotes this time. The actual value of t1 depends on the power supply and the decoupling capacitors used. 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 following order: First ensure that all I/O inputs including ENABLE are at 0V. After that, all VIO_1-3a,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. Page 17 of 33 2019-11-01 2019 Copyright by Acconeer A111 Pulsed Coherent Radar (PCR) Datasheet, v2.0 prel. 7 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 To conclude on optimum distance from the sensor, a simulation/measurement investigation is glass with low permittivity. 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.

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. 2019 Copyright by Acconeer 2019-11-01 Page 18 of 33 A111 Pulsed Coherent Radar (PCR) Datasheet, v2.0 prel. 7.1 Bill of Material (BoM) The below table shows BOM for integration of the A111:

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

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.
