3 Description
The AWRL6432AOP mmWave Sensor device is an Antenna-on-Package (AOP) device that is an evolution
within 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 ARM Cortex M3, 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.
AWRL6432AOP is specifically designed to have separate control for each of the above-mentioned power
domains to control 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 some of 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. AWRL6432AOP is designed for low power, self-monitored,
ultra-accurate radar systems in the automotive space for applications like one row life presence detection,
intrusion detection and exterior intrusion monitoring / radar DVR.
