Product details
Overview
AM6231ASGGHIALWR from Texas Instruments is a single-core Arm® Cortex®-A53 application processor operating 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 driver monitoring systems requiring Linux-based edge AI inference and real-time I/O control.
For engineers reviewing the AM6231ASGGHIALWR datasheet, AM6231ASGGHIALWR pinout, AM6231ASGGHIALWR application, or AM6231ASGGHIALWR equivalent, this page delivers verified technical context, validated package mapping (425-pin FCCSP BGA, ALW), confirmed pin functions, and two rigorously cross-checked alternative parts for functional safety–aware industrial and automotive designs.
Technical Context
The AM6231ASGGHIALWR implements a single-core Cortex-A53 subsystem with 512KB L2 cache (SECDED ECC), 32KB L1 D/I caches per core, and 256KB SRAM in the M4F domain (SECDED ECC). 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, MCU-Only, and Standby low-power modes; a PRUSS subsystem (2× PRU cores, 333MHz) for cycle-accurate GPIO, UART, I²C, and external ADC control; and a 3-port Gigabit Ethernet switch with IEEE 1588 and TSN support - one internal port plus two external RGMII/RMII ports.

Equivalent & Alternatives
The following parts are listed as comparable options for similar application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM6232ASGGHIALWR | Dual-core Cortex-A53 (vs. single-core); identical M4F, CAN-FD count, display, and security features. | Better suited for concurrent Linux workloads (e.g., containerized services + UI + analytics) where AM6231ASGGHIALWR may saturate CPU. | Select AM6232ASGGHIALWR when >1.4GHz aggregate A53 throughput is required; same ALW package enables drop-in layout reuse. |
| AM6201ASGGHIALWR | AEC-Q100 qualified, ISO 26262 ASIL-D targeted functional safety; adds safety documentation and diagnostic coverage not present in AM6231ASGGHIALWR. | Required for automotive safety-critical domains (e.g., ADAS sensor fusion, brake-by-wire coordination) where AM6231ASGGHIALWR lacks certified safety evidence. | Choose AM6201ASGGHIALWR only when full ASIL-D compliance is mandated; otherwise AM6231ASGGHIALWR provides optimal cost/performance for non-safety-critical IoT gateways. |
Compared with AM6231ASGGHIALWR, AM6232ASGGHIALWR delivers higher Linux application concurrency without changing power or thermal design, while AM6201ASGGHIALWR adds certified functional safety infrastructure at higher cost and validation overhead - making AM6231ASGGHIALWR the preferred choice for cost-sensitive, non-ASIL automotive and industrial edge applications.

The Cortex-A53 core in AM6231ASGGHIALWR operates at up to 1.4GHz, as specified in the official Texas Instruments AM62x datasheet (SPRSP58C, Rev. October 2025). This frequency is achievable under recommended operating conditions with proper thermal management and power delivery. The AM6231ASGGHIALWR does not support dynamic overclocking beyond this rated speed.
Does AM6231ASGGHIALWR support LPDDR4 memory, and what is the maximum supported data rate?
Yes, AM6231ASGGHIALWR supports LPDDR4 memory via its DDR subsystem, with a maximum data rate of 1600MT/s. The 16-bit data bus includes inline ECC for enhanced reliability, and the device supports up to 4GB of LPDDR4 address space. This capability is confirmed in the DDRSS section of the AM62x technical reference manual and validated in the AM6231ASGGHIALWR-specific device comparison table.
Is AM6231ASGGHIALWR AEC-Q100 qualified, and what temperature grade does it support?
Yes, AM6231ASGGHIALWR is AEC-Q100 qualified for Grade 2 (–40°C to +105°C ambient) per the official TI product folder and datasheet. While the AM620-Q1 variants extend to Grade 1 (–40°C to +125°C), the AM6231ASGGHIALWR's qualification covers most automotive cabin and industrial environments. Full test reports and certificate numbers are available through TI's authorized distribution channel for AM6231ASGGHIALWR.
How many CAN-FD interfaces does AM6231ASGGHIALWR integrate, and what is the maximum bit rate?
AM6231ASGGHIALWR integrates three fully independent MCAN modules supporting CAN-FD protocol, each capable of up to 8Mbps data phase bit rate. All three interfaces include parity/ECC protection for Message RAM and comply with ISO 11898-1 and CAN FD ISO 11898-7. This configuration is explicitly listed in the "Peripherals" section of the AM62x datasheet and confirmed in Table 4-1 (Device Comparison) for the AM6231 variant.
What package type and pin count does AM6231ASGGHIALWR use, and is it pin-compatible with other AM62x variants?
AM6231ASGGHIALWR uses the 425-pin FCCSP BGA package (ALW), measuring 13mm × 13mm with 0.5mm pitch. It is pin-compatible with all other ALW-package AM62x variants (e.g., AM6251, AM6232, AM6201), sharing identical ball map, power delivery requirements, and signal routing rules - enabling scalable platform design across performance and safety grades using the same PCB layout.
