Description

The IWRL684x mmWave Sensor device is TIs low power and Hardware Security Module (HSM) enabled integrated single chip mmWave sensor based on FMCW radar technology. The device is capable of operation in the 57GHz to 63.9GHz band with 7GHz continuous chirp bandwidth and is designed for various industrial use cases. The device also takes advantage of a low power architecture to enable power-constrained applications. The device is split into the following four switchable power domains:

The IWRL684x is specifically designed to be able to dynamically control the power states of the above-mentioned power domains based on application requirements. The device also features various low-power states and that are achieved by turning off internal IP blocks of the device. IWRL684x device also provides the option of retaining memory during these low power states to retain critical information such as application image and RF profiles across different power modes.

A Hardware Security Module (HSM) is also provisioned in the device (available with 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.

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. IWRL684x is designed for low power, self-monitored, ultra-accurate radar systems in the industrial space for applications like high density people tracking & counting, industrial robots and drones .
