3 Description

The AWR2944P/AWR2E44P is a Performance expansion to the AWR2944 portfolio with enhanced RF and

compute performance to meet NCAP + Automated Driving requirements. The AWR2944P/AWR2E44P is also

a single-chip mmWave sensor composed of a FMCW transceiver, capable of operation in the 76- to 81-GHz

band, radar data processing elements, and peripherals for in-vehicle networking. The AWR2944P/AWR2E44P is

built with TI’s low-power 45-nm RFCMOS process with own recipes to enhance RF and compute performance

enabling unprecedented levels of integration in a small form factor and minimal BOM. The AWR2944P/

AWR2E44P is an ideal solution for low-power, self-monitored, ultra-accurate radar systems in the automotive

space.

The AWR2E44P variant provides customers with an innovative Launch on Package (LOP) antenna feature

which facilitates the attachment of antennas directly on to the package. LOP technology enables loss-less

transmission of signals from the AWR2E44P chip to the antenna via holes in the PCB & launches on the bottom

of the chip. The chip and antenna are directly soldered to the PCB enabling low cost PCB material to be used

instead of expensive high-frequency material.

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. Integrated in the DSP subsystem (DSS), is TI's highperformance

C66x DSP for radar signal processing. 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 2.1) supplements the DSS and

MSS by offloading common radar processing such as FFT, constant false alarm rate (CFAR), scaling, and

compression. This saves MIPS on the DSS and MSS, opening up resources for custom applications and

higher-level 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.

Simple programming model changes can enable a wide variety of sensor implementation (Short, Mid, Long) with

the possibility of dynamic reconfiguration for implementing a multimode sensor.

Additionally, the AWR2944P/AWR2E44P is provided as a complete platform solution including TI hardware and

software reference designs, software drivers, sample configurations, API guides, and user documentation.
