1.1 Introduction

The xWRL6432AOP Evaluation Module (EVM) offered by Texas Instruments presents an easily navigable and cost-effective platform for assessing the capabilities of the xWRL6432AOP mmWave sensing device. Designed with an FR4-based PCB substrate, this evaluation board has seamless integration with the DCA1000EVM for direct connectivity, facilitating raw ADC capture and signal processing development. With a focus on user-friendliness and versatility, the EVM can operate in stand alone mode and includes all features that streamline the initiation of software development for on-chip hardware accelerators and low-power ARM® Cortex® M4F processor.

Key attributes of this EVM include a wide-field-of-view AOP (antenna on package), specifically crafted for in-cabin, wall-mount, and ceiling sensing applications. For efficient code development and debugging, the EVM is equipped with a USB-connected XDS110 JTAG interface. The inclusion of a power-efficient discrete DC-DC regulators enhances overall energy efficiency. Additionally, the EVM incorporates a serial port for programming the onboard QSPI flash and features a 60-pin high-density (HD) connector designed for the capture of raw ADC data from the mmWave radar device.

To facilitate code debugging and data capture, the EVM incorporates an FTDI chip configured for SPI-based raw data capture. The EVM includes CAN-FD transceiver and onboard LIN PHY transceiver for the automotive variant. The EVM has the INA228 high precision current sensors which have remarkable accuracy, measuring current accurately up to micro-amperes. Operating in an independent mode powered via USB, and with an on board 16 MB QSPI flash, this EVM stands as a comprehensive design for developers keen on exploring the potential of the xWRL6432AOP mmWave sensing device.
