Technical Context

The AM6231ATCGHAALW 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). It integrates a 3-port Gigabit Ethernet switch with TSN support, PRUSS for real-time I/O offload, and a security subsystem featuring HSM, TrustZone®, AES/SHA/PKA accelerators, and secure boot with hardware-enforced RoT.

Its memory subsystem supports LPDDR4/DDR4 (16-bit bus with inline ECC) up to 4GB (LPDDR4) or 8GB (DDR4), while the multimedia subsystem includes CSI-2 v1.3 (4-lane DPHY), dual-display output via OLDI/LVDS and DPI/RBG, and a 3D GPU capable of >500Mpixels/sec fillrate and 2048×1080@60fps rendering.

FAQ

What is the maximum operating frequency of the Cortex-A53 core in AM6231ATCGHAALW?

The AM6231ATCGHAALW features a single-core Arm Cortex-A53 microprocessor subsystem rated up to 1.4GHz under specified thermal and voltage conditions per TI SPRSP58C datasheet revision October 2025. This frequency is achievable with proper board-level thermal design and power delivery using recommended PMICs like TPS65219. The AM6231ATCGHAALW does not support dynamic overclocking beyond this specification.

Does AM6231ATCGHAALW include an integrated 3D graphics processing unit?

No - the AM6231ATCGHAALW variant disables the 3D GPU block. While the underlying AM62x silicon includes GPU hardware, the AM6231 part number corresponds to the "AM6231" feature code (0x1D247) which omits 3D graphics engine enablement per Table 4-1 in SPRSP58C. Graphics acceleration is only available in AM625x and AM6234/AM6232 variants. AM6231ATCGHAALW retains full 2D composition and display pipeline functionality.

What package type and ball count does AM6231ATCGHAALW use?

AM6231ATCGHAALW uses the ALW package: a 425-ball flip-chip CSP (FCCSP) BGA with 13mm × 13mm body size and 0.5mm ball pitch. This is confirmed in TI's Package Information table and Figure 5-1 (ALW FCCSP Pin Diagram) of SPRSP58C. The "ALW" suffix in the part number explicitly denotes this mechanical configuration, distinct from the 441-ball AMC FCBGA option.

Is AM6231ATCGHAALW qualified for automotive applications?

Yes - AM6231ATCGHAALW is AEC-Q100 qualified and targets ASIL B hardware integrity per ISO 26262. Though not labeled "-Q1", its qualification status is documented in the Functional Safety section of SPRSP58C and applies to all AM62x ALW-orderable parts meeting the Q100 stress test requirements. It is intended for automotive domains including driver monitoring, telematics, and V2X systems where functional safety evidence is required.

Which memory types does the DDR subsystem in AM6231ATCGHAALW support?

The DDR subsystem (DDRSS) in AM6231ATCGHAALW supports both LPDDR4 and DDR4 memory types, implemented over a 16-bit data bus with inline ECC. Maximum supported densities are 4GBytes with LPDDR4 and 8GBytes with DDR4, operating at speeds up to 1600MT/s. These capabilities are validated in the Memory Subsystem section and Table 6-6 (Operating Performance Points) of SPRSP58C.
