Product details

Overview

AM6231ATGGHAALWR 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 (DPI + OLDI), and hardware-accelerated 3D graphics (OpenGL ES 3.1/Vulkan 1.2). It targets IoT gateways and automotive driver-monitoring systems requiring Linux-based edge AI inference, real-time I/O via PRUSS, and functional safety compliance.

For engineers reviewing the AM6231ATGGHAALWR datasheet, AM6231ATGGHAALWR pinout, AM6231ATGGHAALWR application, or AM6231ATGGHAALWR equivalent, this page delivers verified technical context, package mapping to 425-pin FCCSP BGA (ALW), confirmed pin functions per TI's official pin diagram, and two validated alternative parts for object/gesture recognition SoC use cases.

Technical Context

The AM6231ATGGHAALWR implements a single-core Cortex-A53 subsystem with 512KB L2 cache (SECDED ECC) and 32KB/32KB L1 I/D caches (parity/ECC), paired with a dedicated Cortex-M4F core (256KB SRAM, SECDED ECC) for safety-critical real-time tasks. 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 programmable real-time unit subsystem (PRUSS) with dual 333MHz PRUs, each featuring 16KB program RAM and 8KB data RAM (both SECDED ECC), plus industrial timers and GPIO offload capability. The device includes a 3-port Gigabit Ethernet switch with TSN, IEEE 1588 support, and full CAN-FD (8Mbps, 64-byte payloads) across three independent MCAN modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar application processor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AM6232ATGGHAALWR	Dual-core Cortex-A53 (vs. single-core); identical ALW package, same peripheral set, higher compute throughput.	Better suited for multi-threaded Linux workloads (e.g., concurrent video analytics + web server) where AM6231ATGGHAALWR may bottleneck.	Select AM6232ATGGHAALWR when application demands >1.4GHz aggregate A53 performance without changing PCB layout.

FAQ

What is the maximum operating frequency of the Cortex-A53 core in AM6231ATGGHAALWR?

The AM6231ATGGHAALWR features a single-core Arm Cortex-A53 microprocessor subsystem rated for operation up to 1.4GHz. This speed grade is confirmed in TI's device speed grading documentation (SPRSP58C) and supported by the on-die PLL and thermal design envelope of the ALW package. The AM6231ATGGHAALWR maintains this frequency under recommended operating conditions (junction temperature ≤ 105°C, VDD_CORE = 0.85V–1.1V).

Does AM6231ATGGHAALWR support CAN-FD, and how many interfaces are available?

Yes, AM6231ATGGHAALWR integrates three fully compliant Modular CAN (MCAN) controllers supporting CAN-FD protocol up to 8Mbps with 64-byte data payloads. Each MCAN module includes parity/ECC-protected message RAM and conforms to ISO 11898-1, making AM6231ATGGHAALWR suitable for automotive body control and V2X communication where legacy CAN bandwidth is insufficient.

What display interfaces does AM6231ATGGHAALWR provide, and what resolutions are supported?

AM6231ATGGHAALWR supports dual independent displays: one via 24-bit DPI (LVCMOS RGB) and one via 4-lane OLDI (LVDS). It achieves 1920×1080@60fps on DPI and 1280×720@60fps on OLDI, with independent PLLs for pixel clock generation. Both interfaces include safety features like freeze-frame detection and MISR data integrity checking, as specified in the AM6231ATGGHAALWR technical reference manual.

Is AM6231ATGGHAALWR qualified for automotive applications?

No, AM6231ATGGHAALWR is not AEC-Q100 qualified. It belongs to the standard AM623 series intended for industrial and IoT applications. For automotive use, TI offers the AM620-Q1 variant (e.g., AM6201ATGGHAALWR), which carries AEC-Q100 Grade 2 qualification, ISO 26262 ASIL-B hardware integrity targeting, and functional safety documentation-features absent in the AM6231ATGGHAALWR part number.

What package type and pin count does AM6231ATGGHAALWR use?

AM6231ATGGHAALWR uses the ALW package: a 425-ball flip-chip CSP BGA with 13mm × 13mm body size and 0.5mm ball pitch. This package is documented in TI's Mechanical, Packaging, and Orderable Information (SPRSP58C, Section 11.1) and matches the pin diagram shown in Figure 5-1 of the AM62x datasheet. The ALW package is distinct from the larger 441-ball AMC FCBGA used in higher-tier variants.
