AWRL6844 Présentation
A mmWave radar sensor is a radar device that transmits and receives millimeter-wave electromagnetic signals (here 57 to 64GHz) and processes frequency-modulated continuous wave (FMCW) reflections to measure range, velocity, and angle of objects. Within the sensing hierarchy, it belongs to: radar sensor -> mmWave sensor -> integrated RF SoC -> semiconductor sensor device. The AWRL6844 belongs to the AWRL684x automotive family, alongside the related AWRL6843.
Key features include the 57-64GHz band with 7GHz continuous chirp bandwidth for fine range resolution, an integrated Hardware Security Module (HSM) for secure in-cabin sensing, TI's low-power 45nm RF CMOS process enabling unprecedented integration in an extremely small form factor, and a compact 10.4 x 10.4 mm package suitable for hidden in-cabin mounting. The device is built for self-monitored, ultra-accurate radar systems in the automotive space.
Technically, the AWRL6844 integrates a fully programmable radar front-end with an ARM Cortex-R4F processing core and hardware FFT acceleration on a single die, reducing BOM cost and board area versus discrete RF-plus-MCU solutions. Communication interfaces include CAN, I2C, LIN, SPI, and UART outputs (as seen on the AWRL6844DBGANCRQ1 device variant), enabling direct integration into vehicle body and domain controller networks.
Typical applications include child presence detection (CPD) for Euro NCAP requirements, intrusion monitoring for anti-theft, occupancy detection for seatbelt and airbag logic, and gesture or vital-sign sensing inside the vehicle cabin. The 60GHz-class band and 7GHz bandwidth allow detection of micro-movements such as breathing even through seat covers.
Design consideration: the AWRL6844 uses a different SDK and register/memory map than the earlier IWR6843, so migration requires software rework even where hardware function is similar. Plan for the MMWAVE L-SDK and Code Composer Studio device support packages early in development. Pricing and packaging details should be verified with TI or distributors as of 2026-08-29.

Applications typiques
AWRL6844 convient pour 6 applications: Child Presence Detection (CPD), Intrusion Monitoring, Occupancy Detection and Seatbelt Logic, In-Cabin Vital Sign and Gesture Sensing, Automotive Body Controller Integration, Rapid Prototyping and Evaluation.
Child Presence Detection (CPD)
The AWRL6844 is purpose-built for child presence detection in automotive cabins. Its 57-63.9GHz operation with 7GHz continuous chirp bandwidth provides centimeter-level range resolution, sufficient to detect the micro-movements of a sleeping child such as breathing, even through seat covers and blankets. The integrated ARM Cortex-R4F core and hardware FFT accelerator process the radar point cloud on-chip, enabling a self-contained CPD node that reports occupancy over CAN or LIN without an external host processor. TI provides dedicated InCabin demo examples in the Radar Toolbox to shorten time to Euro NCAP-aligned system designs.
Recommandé
Intrusion Monitoring
For vehicle intrusion monitoring, the AWRL6844 detects unauthorized movement inside the cabin using FMCW chirps in the 57-64GHz band. The 7GHz bandwidth allows the sensor to separate small motion signatures from static clutter, and the HSM (Hardware Security Module) protects sensor data integrity against tampering - an important differentiator for security applications. The low-power 45nm RF CMOS design allows the sensor to remain active in parked-vehicle scenarios where battery drain is tightly budgeted, waking the body controller via UART or CAN when occupancy is detected.
Recommandé
Occupancy Detection and Seatbelt Logic
The AWRL6844 supports seat-level occupancy detection for seatbelt reminder and airbag deployment logic. Its ultra-accurate radar sensing distinguishes adult, child, child seat, and empty-seat scenarios by analyzing micro-Doppler signatures from breathing and heartbeat. Operating at 60GHz-class frequencies avoids interference with longer-range 77GHz front radar, and the small 10.4 x 10.4 mm package hides easily inside seat frames or headliners. The radar data is transmitted over SPI or CAN to the vehicle domain controller for safety decision processing.
Recommandé
In-Cabin Vital Sign and Gesture Sensing
Beyond occupancy counting, the AWRL6844 enables vital-sign monitoring (heart rate, respiration) and simple in-cabin gesture control. The 7GHz chirp bandwidth and integrated FFT accelerator resolve sub-millimeter chest displacement, while the programmable front-end allows custom chirp profiles for gesture recognition. The device's low power consumption, achieved through TI's 45nm RF CMOS process and power-down modes, suits always-on driver monitoring. TI's Radar Toolbox InCabin demos provide reference implementations for these use cases, reducing algorithm development effort.
Recommandé
Automotive Body Controller Integration
The AWRL6844 integrates directly into body and domain controller networks via its CAN, LIN, UART, and SPI interfaces. A typical architecture places the sensor in the overhead console or B-pillar, with the AWRL6844 processing raw chirps internally and transmitting only detected-object TLV data over CAN, minimizing bus load. The HSM enables authenticated firmware and secure sensor output, which increasingly matters for EU regulations covering in-cabin sensing. TI's L-SDK CAN Integration example demonstrates point-cloud transmission over CAN for AWRL6844 designs.
Recommandé
Rapid Prototyping and Evaluation
The AWRL6844EVM evaluation module allows engineers to prototype in-cabin radar systems without designing custom RF boards. Combined with Code Composer Studio device support for xWRL6844 and the MMWAVE L-SDK, the EVM supports out-of-box child presence detection, occupancy, and intrusion demos from TI's Radar Toolbox on dev.ti.com. Engineers should note that code does not port 1-to-1 from IWR6843 platforms - SDKs, firmware packages, memory maps, and registers differ - so budget software migration time when moving prototypes to production hardware.

Notes de conception
The AWRL6844 is an RF SoC with on-package antenna considerations; the 10.4 x 10.4 mm package and 57-64GHz operation demand careful stackup design with controlled-impedance RF feed lines and a solid ground plane directly beneath the device. Follow the AWRL6844EVM reference layout from TI rather than generic FR4 practices, since 60GHz-class loss in standard FR4 is significant. Use the EVM layout files in the Radar Toolbox as the starting point for your production board.
Do not assume software portability from IWR6843. Per TI E2E guidance, the AWRL6844 uses the MMWAVE L-SDK with different drivers, front-end controller firmware packages, memory mappings, and registers versus the legacy mmWave SDK. Plan a software re-architecture phase rather than a code port. Also ensure Code Composer Studio has the updated mmWave Sensors device package that added xWRL6844 support before attempting to flash the device.
The AWRL6844 outputs in-cabin sensing results over CAN, LIN, SPI, UART, or I2C. When routing CAN/LIN lines in a vehicle harness, use proper AEC-qualified transceivers (for example TI TCAN and TLIN family parts) with common-mode filtering, and keep the SPI clock lines short and referenced to ground to avoid corrupting high-rate point-cloud transfers. Enable the on-chip HSM for authenticated data when the radar output feeds safety-relevant decisions.
