3 Description
The AWR2544 is a single-chip mmWave sensor composed of a FMCW transceiver. The device is capable of
operation in the 76 to 81GHz (EHF) band, includes radar data processing elements, and a rich set of peripherals
for in-vehicle networking. AWR2544 provides customers with an additional Launch on package (LOP) antenna
feature which facilitates the attachment of antennas directly on to the package. The AWR2544 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. The AWR2544 is designed for low-power, self-monitored, ultra-accurate radar systems in the
automotive space.
TI’s low-power 45nm RFCMOS process enables a monolithic implementation of a 4 TX, 4 RX system with
integrated PLL, VCO, mixer, and baseband ADC. 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 Cortex-R5F processor allowing for custom control
and automotive interface applications. The hardware accelerator block (HWA 1.5) supplements the MSS by
offloading common radar processing such as FFT, scaling, and compression. This saves MIPS on the external
processor, opening up resources for custom applications and implementation of higher-level post-processing
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.
