The AWR294x is a single chip mmWave Sensor composed of a FMCW transceiver, capable of operation in the 76-81 GHz band, radar data processing elements, and peripherals for in-vehicle networking. It is built with TI’s low power, 45 nm RFCMOS process and enables unprecedented levels of integration in a small form factor and minimal BOM. AWR294x is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the automotive space.

TI’s low-power, 45-nm RFCMOS process enables a monolithic implementation of a 3-4 TX, 4 RX system with integrated PLL, VCO, mixer, and baseband ADC. Integrated in the DSP Subsystem (DSS), is TI’s high-performance C66x DSP for radar signal processing. The device includes a Radio Processor Subsystem (RSS), which is responsible for radar front-end configuration, control, and calibration. Within the Main Subsystem (MSS), the device implements a user programmable ARM R5F allowing for custom control and automotive interface applications. The Hardware Accelerator block (HWA 2.0) supplements the DSS and MSS by offloading comon radar processing such as FFT, Constant False Alarm rate (CFAR), scaling, and compression. This saves MIPS on the DSS and MSS, opening up resources for custom applications and higher level algorithms.

A Hardware Security Module (HSM) is also provisioned in the device (available for only Secure Part variants). The HSM consists of a programmable ARM Cortex M4 core and the necessary infrastructure to provide a secure zone of operation within the device.

Simple programming model changes can enable a wide variety of sensor implementation (Short, Mid, Long) with the possibility of dynamic reconfiguration for implementing a multimode sensor.

Additionally, the AWR294x device is provided as a complete platform solution including TI hardware and software reference designs, software drivers, sample configurations, API guides, and user documentation.
