AM6251ATCGHAALW

Microprocessors Overview

The AM6251ATCGHAALW is a microprocessor from the Texas Instruments Sitara AM62x family, featuring a single 64-bit Arm Cortex-A53 core and a single Arm Cortex-M4F MCU. It operates at up to 1.4 GHz for the A53 and 400 MHz for the M4F. The device includes a 3D graphics processing unit, dual display support via DPI and OLDI interfaces, and a camera serial interface (CSI-Rx). Connectivity options include two USB 2.0 ports, a Gigabit Ethernet switch with TSN, three CAN-FD modules, and multiple UART, SPI, and I2C controllers. It utilizes a 425-pin FCCSP package.

Microprocessors Feature Summary

• Integrated 3D Graphics Processing Unit supporting OpenGL ES 3.1 and Vulkan 1.2
• Dual-display subsystem with independent PLLs for DPI and OLDI outputs
• Hardware security features including secure boot, AES/SHA acceleration, and ARM TrustZone
• Programmable Real-Time Unit Subsystem (PRUSS) for cycle-accurate protocols

Microprocessors Applications

• Human Machine Interfaces (HMI)
• Retail automation
• Driver Monitoring System (DMS/OMS) / In-Cabin Monitoring (ICM)
• Telematics Control Unit (TCU)

Microprocessors Procurement Notes

Verify the specific speed grade suffix 'T' against the required operating frequency. Confirm the 'ALW' suffix corresponds to the 425-ball FCCSP package dimensions. Ensure the ordering code matches the intended feature set, as PRUSS availability depends on the Features code. Check for functional safety requirements if targeting automotive applications.

Microprocessors Selection Notes

Select this part for applications requiring a balance of multimedia performance and real-time control. The single-core A53 configuration suits cost-sensitive HMI designs. Verify peripheral multiplexing constraints using the SysConfig tool. Consider the integrated PRUSS for deterministic I/O tasks without burdening the main processor cores.

Microprocessors Part Context
