8.1 Overview

The IWRL6432AOP device is a complete SOC which include mmWave front end, customer programmable MCU and analog baseband signal chain for two transmitters and three receivers. This device is intended as a radar-on-a-chip in use-cases with quality provision for memory, processing capacity and application code size. Use-cases include cost-effective industrial radar sensing applications. Examples are:

• Industrial-level sensing

• Industrial automation sensor fusion with radar

• Traffic intersection monitoring with radar

• Industrial radar-proximity monitoring

• People counting

• Gesture detection

In terms of scalability, the IWRL6432AOP device can be paired with a low-end external MCU to address more complex applications that can require additional memory for a larger application software footprint and faster interfaces.
