3 Description

The AWRL6432 mmWave Sensor device is an integrated single chip mmWave sensor based on FMCW radar

technology. The device is capable of operation in the 57GHz to 63.9GHz band and is partitioned into mainly four

power domains:

• RF/Analog Sub-System: This block includes all the RF and Analog components required to transmit and

receive the RF signals.

• Front-End Controller sub-System (FECSS): FECSS contains processor, responsible for radar front-end

configuration, control, and calibration.

• Application Sub-System (APPSS): APPSS is where the device implements a user programmable ARM

Cortex M4 allowing for custom control and automotive interface applications. Top Sub-System (TOPSS) is

part of the APPSS power domain and contains the clocking and power management sub-blocks.

• Hardware Accelerator (HWA): HWA block supplements the APPSS by offloading common radar processing

such as FFT, Constant False Alarm rate (CFAR), scaling, and compression.

AWRL6432 is specifically designed to have separate control for each of the above-mentioned power domains to

control the states (power ON or OFF) based on use case requirements. The device also features the capability

to exercise various low-power states like sleep and deep sleep, where low-power sleep mode is achieved by

clock gating and by turning off the internal IP blocks of the device. The device also provides the option of

keeping some contents of the device, like Application image or RF profile retained in such scenarios.

Additionally, the device is built with TI’s low power 45nm RF CMOS process and enables unprecedented

levels of integration in an extremely small form factor. AWRL6432 is designed for low power, self-monitored,

ultra-accurate radar systems in the automotive space for applications like child presence detection, intrusion

monitoring, gesture detection, and occupancy detection.
