Texas Instruments AM6232ATGGHAALWR

Overview

AM6232ATGGHAALWR from Texas Instruments is a dual-core Arm® Cortex®-A53 application processor with integrated Arm® Cortex®-M4F MCU, 3D graphics engine (OpenGL ES 3.1/Vulkan 1.2), dual-display support (1920×1080@60fps each), and full CAN-FD (up to 8Mbps). It targets Linux-based automotive and industrial HMI systems requiring real-time I/O, secure boot, and functional safety–capable architecture.

For engineers reviewing the AM6232ATGGHAALWR datasheet, AM6232ATGGHAALWR pinout, AM6232ATGGHAALWR application, or AM6232ATGGHAALWR equivalent, this page delivers verified core count, display bandwidth, security subsystem capabilities, DDR4/LPDDR4 memory interface specs, and functional safety targeting (ASIL B hardware integrity, ASIL D systematic capability).

Technical Context

The AM6232ATGGHAALWR implements a dual-core Cortex-A53 cluster (up to 1.4GHz) with 512KB L2 cache (SECDED ECC), paired with a dedicated 400MHz Cortex-M4F subsystem (256KB SRAM, SECDED ECC) for safety-critical or real-time tasks. Its multimedia subsystem includes a dual-display controller supporting OLDI (LVDS) and DPI (24-bit RGB), plus a CSI-2 v1.3 receiver with 4-lane D-PHY (1.5Gbps/lane) and ECC-protected DMA streaming to DDR.

Security is enforced via hardware root-of-trust, Arm TrustZone®-based TEE, dedicated HSM with PKA/AES/SHA accelerators, and Replay Protected Memory Block (RPMB). Power management includes DeepSleep, MCU-only, and Standby modes with partial IO wakeup (CAN/GPIO/UART), and it requires companion PMIC TPS65219 for optimal voltage sequencing.

Key Specifications

Pinout & Package

AM6232ATGGHAALWR uses a 425-ball FCCSP BGA package (ALW variant), 13mm × 13mm, 0.5mm pitch. Pinout conforms to TI's ALW mechanical layout (Figure 5-1, SPRSP58C), with dedicated ball groups for DDR0, OSPI0, GPMC0, OLDI0, CSI-RX, RGMII, USB, CAN-FD, and power domains (VDD_CORE, VDDSHV, VDDS_DDR, etc.). All I/Os are LVCMOS-compatible and configurable as GPIO.

FAQ

What is the maximum display resolution supported by AM6232ATGGHAALWR?

AM6232ATGGHAALWR supports dual independent displays: one at 1920×1080@60fps via OLDI (LVDS) and another at 1280×720@60fps via DPI (24-bit RGB), or combined as 2048×1080 + 1280×720. The pixel clock supports up to 165MHz, enabling full-HD timing across both outputs. This capability is confirmed in the AM62x datasheet Section 1 (Features) and applies specifically to the AM6232ATGGHAALWR variant.

Does AM6232ATGGHAALWR include a 3D graphics processing unit?

No, AM6232ATGGHAALWR does not include the 3D graphics engine. Per Table 4-1 (Device Comparison) in the AM62x datasheet, the "3D Graphics Engine" feature is marked "No" for all AM623x variants including AM6232ATGGHAALWR. Graphics acceleration is present only in AM625x and AM620-Q1 devices. The AM6232ATGGHAALWR retains full dual-display controller functionality but relies on CPU-based 2D composition.

What functional safety certifications apply to AM6232ATGGHAALWR?

AM6232ATGGHAALWR is AEC-Q100 qualified and targets ISO 26262 compliance with systematic capability up to ASIL D and hardware integrity up to ASIL B. TI provides functional safety documentation to aid system-level design, and TÜV SÜD certification is planned. These claims are explicitly stated in the "Functional Safety" section of the AM62x datasheet (SPRSP58C) and apply to the AM6232ATGGHAALWR orderable part.

Which memory types does AM6232ATGGHAALWR support through its DDR subsystem?

AM6232ATGGHAALWR supports both LPDDR4 and DDR4 memory types via its 16-bit DDR subsystem with inline ECC. It achieves speeds up to 1600MT/s and supports up to 4GB addressable space with LPDDR4 or 8GB with DDR4. This is documented in the "Memory Subsystem" section and Table 4-1 of the AM62x datasheet, and applies directly to the AM6232ATGGHAALWR device.

Is AM6232ATGGHAALWR pin-compatible with other AM62x processors in the ALW package?

Yes, AM6232ATGGHAALWR shares the same 425-ball FCCSP BGA (ALW) package, 13mm × 13mm footprint, and identical pinout with AM625, AM625-Q1, AM623, and AM620-Q1 in the ALW variant. Mechanical and signal compatibility is confirmed in Section 11.1 (Packaging Information) and Figure 5-1 (ALW Pin Diagram) of the AM62x datasheet, enabling drop-in replacement where feature sets align.
