TDA4VL21HGAALZRQ1 - 4 TOPS ADAS SoC | Texas Instruments

The Texas Instruments TDA4VL21HGAALZRQ1 is an automotive system-on-chip (SoC) from the Jacinto TDA4VL-Q1 processor family, engineered for vision perception and analytics. It integrates dual Arm Cortex-A72 cores running up to 2 GHz, Arm Cortex-R5F cores up to 1 GHz, C7x and C66x DSPs up to 1 GHz, an integrated GPU, and a deep-learning accelerator delivering 4 TOPS of AI performance. The device is housed in a 770-ball FCBGA (ALZ) package measuring 23 x 23 mm with 0.8 mm terminal pitch and is rated from -40C to +125C for automotive environments.

An automotive vision SoC is a single-chip microprocessor (MPU) subsystem that combines a general-purpose application-processor cluster, a real-time MCU island, digital signal processors, dedicated neural-network acceleration, graphics, and rich automotive I/O on one die. Within the semiconductor hierarchy - semiconductor to microprocessor to system-on-chip to ADAS vision processor - the TDA4VL-Q1 represents the cost-optimized tier of TI's Jacinto platform, sharing its architecture, package technology, and software stack with the TDA4VE and TDA4AL family members under one datasheet.

Key features begin with the 4 TOPS deep-learning engine, which executes object-detection, classification, and segmentation networks for camera-based ADAS. Heterogeneous compute lets the Cortex-A72 cluster run high-level operating systems while Cortex-R5F cores close real-time safety loops and the C7x/C66x DSPs accelerate vision kernels. Distributor parametric data lists a 0.84 V maximum core supply, 770 terminals, and device marking TDA4VL21 at silicon revision 1.0.

Technically, the TDA4VL21HGAALZRQ1 is covered by the 251-page TI datasheet TDA4VE/TDA4AL/TDA4VL Jacinto Processors, Silicon Revision 1.0, confirming that the ball map, board design, and boot configuration are common across the three variants - a significant advantage for platform reuse and mid-cycle cost-downs. DigiKey and Mouser list the part as an automotive system-on-a-chip with AI accelerator in the 770-FCBGA (23x23) package.

Typical applications include single front-camera ADAS ECUs using 4 TOPS neural inference, driver and in-cabin monitoring systems, multi-camera surround view, radar-vision sensor fusion with devices such as the AWR2188 mmWave radar, and industrial edge-AI vision nodes. Companion XAIPART listings include the AR0821CS image sensor and TI automotive PMICs.

Design consideration: validate silicon revision 1.0 errata before production, implement the power-up sequencing defined in the TI datasheet with an automotive PMIC, and budget thermal relief under the 23 x 23 mm FCBGA, since high-TOPS workloads concentrate heat in the die area.
