Product details
Overview
AM6231ATGGHIALWR from Texas Instruments is a single-core Arm® Cortex®-A53 application processor operating at up to 1.4GHz, integrated with a 256KB SECDED ECC-protected Cortex-M4F MCU subsystem, dual-display support (1920×1080@60fps), 3D graphics engine (OpenGL ES 3.1/Vulkan 1.2), and full CAN-FD (up to 8Mbps) for automotive driver monitoring systems.
For engineers reviewing the AM6231ATGGHIALWR datasheet, AM6231ATGGHIALWR pinout, AM6231ATGGHIALWR application, or AM6231ATGGHIALWR equivalent, this page delivers verified core count, display capability, safety certification status (AEC-Q100 qualified), memory interface specs (LPDDR4/DDR4 with inline ECC), and functional safety targeting (ASIL B hardware integrity).
Technical Context
The AM6231ATGGHIALWR implements a single-core Cortex-A53 cluster with 512KB shared L2 cache (SECDED ECC), paired with a dedicated Cortex-M4F subsystem running at up to 400MHz and backed by 256KB on-chip SRAM (SECDED ECC). Its multimedia subsystem includes a dual-display controller supporting OLDI (LVDS) and DPI (24-bit RGB) outputs, plus a CSI-2 v1.3 receiver with 4-lane D-PHY for camera input.
Functional safety is architecturally supported via isolated M4F execution, dedicated Device/Power Manager, freeze-frame detection in display path, MISR data checking, and hardware-level ECC across all on-chip RAM blocks (OCSRAM, SMS, MCU, DPM). Security is enforced through hardware root-of-trust, Arm TrustZone®, dedicated HSM, and cryptographic accelerators (AES-128/192/256, SHA2, PKA, DRBG).

FAQ
What is the maximum operating frequency of the Cortex-A53 core in AM6231ATGGHIALWR?
The Cortex-A53 core in AM6231ATGGHIALWR operates at up to 1.4GHz, as confirmed in the AM62x datasheet SPRSP58C Section 1 (Features) and Table 4-1 (Device Comparison). This speed grade is fixed for the AM6231 variant and does not support dynamic scaling beyond this limit. The AM6231ATGGHIALWR achieves this frequency with validated thermal and power delivery design, enabling full-HD UI rendering and lightweight neural network inference without throttling under sustained load.
Does AM6231ATGGHIALWR support CAN-FD, and what is the maximum bit rate?
Yes, AM6231ATGGHIALWR integrates three fully compliant CAN-FD modules supporting up to 8Mbps data phase bit rates, as specified in Section 1 (Features) and Table 4-1. Each module implements parity/ECC checking on Message RAM and conforms to ISO 11898-1 and CAN Protocol 2.0 A/B. The AM6231ATGGHIALWR uses these interfaces for high-bandwidth communication with ADAS ECUs and body control modules in automotive applications.
What display interfaces does AM6231ATGGHIALWR support, and what resolutions are achievable?
AM6231ATGGHIALWR supports dual-display output via OLDI (4-lane LVDS) and DPI (24-bit RGB LVCMOS). It delivers up to 1920×1080@60fps per display or asymmetric configurations like 2048×1080 + 1280×720, with independent PLLs enabling precise pixel clock generation up to 165MHz. These capabilities are documented in Section 1 (Multimedia → Display subsystem) and confirmed in the functional block diagram (Figure 3-1). The AM6231ATGGHIALWR uses this for automotive digital clusters and infotainment overlays.
Is AM6231ATGGHIALWR AEC-Q100 qualified, and what temperature grade does it support?
Yes, AM6231ATGGHIALWR is AEC-Q100 qualified per Section 1 (Functional Safety) and Table 4-1, falling under the AM623 product line which shares qualification with AM625-Q1 and AM620-Q1 variants. It supports Grade 2 (−40°C to +105°C ambient) operation, validated for under-hood and cabin-mounted automotive applications. This qualification is integral to the AM6231ATGGHIALWR device definition and enables use in production vehicles without additional component-level stress testing.
What security features are implemented in AM6231ATGGHIALWR for secure boot and runtime protection?
AM6231ATGGHIALWR implements hardware-enforced secure boot with programmable backup key switching, Arm TrustZone®-based Trusted Execution Environment (TEE), dedicated Security Controller with user-programmable HSM core, and cryptographic acceleration for AES-128/192/256, SHA2, PKA, and DRBG. These features - detailed in Section 1 (Security) - establish a hardware root-of-trust, enable replay-protected storage (RPMB), and isolate secure workloads from the main OS. The AM6231ATGGHIALWR leverages these to prevent firmware tampering and protect IP in deployed gateways and DMS systems.
