REGULATORY APPROVALS See Regulatory Information section Decawave Ltd 2018 Subject to change without notice Version 1.2 Page 4 DWM1004C Datasheet 1 OVERVIEW The block diagram on page 1 of this data sheet shows the major sections of the DWM1004C. An overview of these blocks is given below. 1.1 UWB Transceiver DW1000 The module has a DW1000 UWB transceiver mounted on the PCB. The DW1000 uses a 38.4 MHz reference crystal. The crystal has been trimmed in production to reduce the initial frequency error to approximately 3 ppm, using the DW1000 ICs internal on-chip crystal trimming circuit. Always-On (AON) memory can be used to retain DW1000 configuration data during the lowest power operational states when the on-chip voltage regulators are disabled. This data is uploaded and downloaded automatically. Use of DW1000 AON memory is configurable. The on-chip voltage and temperature monitors allow the host to read the voltage on the VDDAON pin and the internal die temperature information from the DW1000. See the DW1000 Datasheet for more detailed information on device functionality, electrical specifications and typical performance. 1.2 Microprocessor STM32L041G6UxS The STM32L041G6UxS is an ultra-low power Cortex-M0+ CPU with 32kB flash memory and 8kB RAM. It supports SPI, I2C and UART serial interfaces and has an AES hardware block. See the STM32L041G6UxS Datasheet for more detailed information on device functionality, electrical specifications and typical performance. 1.3 UWB Antenna ACS5200HFAUWB The fixed UWB antenna mounted on the DWM1004C Module is from Partron, ACS5200HFAUWB. 1.4 Three Axis Motion Detector STMicroelectronics LIS3DH The LIS3DH is an ultra-low-power high performance three-axis linear accelerometer with digital I2C/SPI serial interface standard output. See the LIS3DH Datasheet for more detailed information on device functionality, electrical specifications and typical performance. 1.5 Power Supply and Power management The power management circuit consists of a switch mode regulator. It is a buck convertor or step down convertor. The input voltage to the DWM1004C can be in the range 2.8V to 3.6V. Outputs from the convertor provides 1.8V which is required by the DW1000. 1.6 Software The DWM1004C module is shipped pre-loaded with embedded firmware which provides host selectable TDoA blink format support for UWB CH5 6.5GHz, CH2 4GHz and 6.8Mbps data rates. If relevant, download the appropriate software from Decawave.com to begin developing your own applications. The firmware contains a driver through which host application software can communicate to the DWM1004C device. The firmware offers the following features: Serial communication from a host device to allow adjustment of channel, configuration of blink rate and configuration of accelerometer settings. The firmware translates host command to DWM1004C actions. The firmware ensures that certain regulatory restrictions are adhered to (channel, data rate, PRF, Preamble etc). Per KDB 996369 D03, accompanying firmware for the DWM1004C allows customers to place the part in various test modes, for example continuous frame and continuous wave mode. The firmware and detailed test mode description is available as a download from Decawave.com. Decawave Ltd 2018 Subject to change without notice Version 1.2 Page 5 DWM1004C Datasheet 2 DWM1004C CALIBRATION Depending on the end-use applications and the system design, DWM1004C settings may need to be tuned. To help with this tuning several built in functions such as continuous wave transmission and continuous packet transmission can be enabled. See the DW1000 User Manual for further details. 2.1.1 Crystal Oscillator Trim DWM1004C modules are calibrated at production to minimise initial frequency error to reduce carrier frequency offset between modules and thus improve receiver sensitivity. The calibration carried out at module production will trim the initial frequency offset to less than 3 ppm, typically. 2.1.2 Transmitter Calibration The DWM1004C is calibrated in module production, the calibrated values is permanently stored in the DW1000 OTP. This module is calibrated to meet the regulatory power spectral density requirement of less than -

41.3 dBm/MHz. 2.1.3 Antenna Delay Calibration In order to measure range accurately, precise calculation of timestamps is required. To do this the antenna delay must be known. The DWM1004C allows this delay to be calibrated and provides the facility to compensate for delays introduced by PCB, external components, antenna and internal DWM1004C delays. When using the pre-loaded embedded firmware of the DWM1004C module, the Antenna Delay has been pre-

calibrated for this configuration. The antenna delay is stored in OTP memory. To calibrate the antenna delay, range is measured at a known distance using two DWM1004C systems. Antenna delay is adjusted until the known distance and reported range agree. For best ranging accuracy antenna delay should be carried out as a once off measurement for each DWM1004C design implementation. If required, for greater accuracy, antenna delay calibration should be carried out on a per DWM1004C module basis, see DW1000 User Manual for full details.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
