Product details
Overview
AM6231AKGGHHALW from Texas Instruments is a single-core Arm® Cortex®-A53 application processor operating at up to 1.4GHz, integrated with a 400MHz Cortex-M4F MCU, 3× CAN-FD interfaces, dual-display support (1920×1080@60fps), and hardware-accelerated 3D graphics (OpenGL ES 3.1/Vulkan 1.2). It targets IoT gateways and automotive in-cabin systems requiring real-time I/O, secure boot, and functional safety support.
For engineers reviewing the AM6231AKGGHHALW datasheet, AM6231AKGGHHALW pinout, AM6231AKGGHHALW application, or AM6231AKGGHHALW equivalent, this page delivers verified technical context, validated package mapping, confirmed pin functions, and two rigorously cross-checked alternative parts for industrial and automotive Linux-based designs.
Technical Context
The AM6231AKGGHHALW implements a single-core Cortex-A53 subsystem with 512KB L2 cache (SECDED ECC), 32KB L1 D/I caches per core, and 256KB SRAM with SECDED ECC in the M4F domain. Its DDR subsystem supports LPDDR4/DDR4 at 1600MT/s with 16-bit bus and inline ECC, enabling up to 4GB (LPDDR4) or 8GB (DDR4) addressable memory.
It integrates a dedicated Device/Power Manager for DeepSleep, Standby, and MCU-only low-power modes; a PRUSS with dual 333MHz cores for GPIO, UART, I²C, and ADC offload; and a 3-port Gigabit Ethernet switch with IEEE 1588, TSN, and hardware checksum offload - all isolated via firewall and TrustZone®-enabled TEE.
