Product details
Overview
AM6254ATLHJAMKR from Texas Instruments is a System-in-Package (SiP) Arm® Cortex®-A53 application processor integrating 512MB LPDDR4 SDRAM, delivering up to 1.4GHz quad-core performance, dual-display support (1920×1080@60fps each), and hardware-accelerated 3D graphics (>500 MPixels/s, OpenGL ES 3.1/Vulkan 1.2) for industrial HMI and medical device user interfaces.
For engineers reviewing the AM6254ATLHJAMKR datasheet, AM6254ATLHJAMKR pinout, AM6254ATLHJAMKR application, or AM6254ATLHJAMKR equivalent, this page delivers verified technical context, validated package mapping (425-pin FCCSP BGA, 13mm × 13mm), confirmed security features (Secure Boot with RoT, TrustZone TEE, HSM), real-time I/O via dual PRU cores, and Ethernet TSN support - all specific to the AM6254ATLHJAMKR SiP variant.
Technical Context
The AM6254ATLHJAMKR implements a quad-core Arm Cortex-A53 cluster with 512KB shared L2 cache (SECDED ECC), paired with a dedicated Cortex-M4F MCU (400MHz, 256KB SRAM with SECDED ECC) and dual-programmable PRU subsystems (333MHz, 16KB program + 8KB data memory per PRU). Its DDRSS integrates 512MB LPDDR4 (16-bit bus, inline ECC, 1600MT/s) directly into the SiP, eliminating external memory routing.
Security is enforced through hardware-rooted Secure Boot, Arm TrustZone-based TEE, firewall-isolated SMS subsystem, and dedicated cryptographic accelerators (AES-128/192/256, SHA2-224/256/384/512, PKA, DRBG with TRNG). The device supports Time-Sensitive Networking (TSN) via its 2-port Gigabit Ethernet switch (RGMII/RMII, IEEE 1588 Annex D/E/F, 802.1AS PTP) and full CAN-FD (8Mbps, 64-byte payloads).

Pinout & Package
AM6254ATLHJAMKR uses a 13mm × 13mm, 0.5-mm pitch, 425-ball FCCSP BGA package (AMK). Power delivery includes dedicated VDDS_DDR, VDDS_MEM_1P1 (1.1V IO), and VDDS_MEM_1P8 (1.8V core) rails for the integrated LPDDR4. DDR-related pins (e.g., M9, F2, G2, N1, DDR_ZQ) are reassigned from standard AM6254 DDR signals to optimized SiP power and calibration functions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDS_DDR (M9) | DDR PHY IO supply | Provides regulated 1.1V to LPDDR4 PHY interface; critical for signal integrity at 1600MT/s |
| VDDS_MEM_1P1 (F2, G2) | SDRAM IO supply | Sources LPDDR4 VDD2/VDDQ rails; requires tight regulation (±3% over temp) |
| VDDS_MEM_1P8 (H1, H2, N3) | SDRAM Core supply | Sources LPDDR4 VDD1 rail; enables low-power retention modes and stable core operation |
| DDR_ZQ (N2, R2) | SDRAM Calibration Reference | Connects to external 240Ω ±1% resistor for ZQ calibration; ensures impedance matching for DDR timing |
| VSS (E1, E2, F1, etc.) | Ground | LPDDR4 VSS/VSSQ return path; multiple dedicated balls minimize ground bounce in high-speed DDR operation |
Key Features

| PRU Real-Time I/O | Dual 333MHz PRUs with SECDED ECC memory and CRC32/16 acceleration enable deterministic GPIO, UART, I²C, and ADC control without CPU intervention |
| Time-Sensitive Networking | Hardware TSN support (IEEE 1588 Annex D/E/F, 802.1AS) enables sub-microsecond time synchronization and scheduled traffic shaping for industrial automation |
| Secure Boot & TEE | Hardware-enforced RoT with backup key switching, TrustZone isolation, RPMB, and dedicated HSM core provide end-to-end firmware protection and secure storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM6254ALWJAA | Same core silicon but in ALW package (425-pin FCCSP) without integrated LPDDR4; requires external 512MB LPDDR4 routing and PMIC sequencing | Used where design flexibility for memory capacity scaling (e.g., 1GB+), custom DDR layout, or thermal management via exposed die pad is required | Select AM6254ALWJAA only if external memory customization or thermal dissipation beyond SiP limits is needed; AM6254ATLHJAMKR reduces layout risk and BOM cost. |
| AM6234ATLHJAMKR | Lower-cost variant with dual Cortex-A53 cores (vs. quad), no integrated LPDDR4, reduced peripheral count (2x CAN-FD vs. 3x, no TSN), and lower GPU performance | Targeted at cost-sensitive HMIs with single-display UI and basic connectivity (USB, UART, I²C), not suitable for dual-display or TSN-critical applications | Choose AM6234ATLHJAMKR only for non-dual-display, non-TSN, and non-LPDDR4-integrated designs; AM6254ATLHJAMKR provides guaranteed dual-display and TSN capability. |
Compared with AM6254ALWJAA, AM6254ATLHJAMKR eliminates DDR layout complexity and reduces component count, while AM6234ATLHJAMKR lacks both the integrated memory and dual-display/TSN features essential for industrial HMI and medical monitoring use cases.

FAQ
What distinguishes AM6254ATLHJAMKR from the standard AM6254 processor?
The AM6254ATLHJAMKR is a System-in-Package (SiP) variant that integrates 512MB LPDDR4 SDRAM directly with the AM6254 die, whereas standard AM6254 processors (e.g., AM6254ALWJAA) require external LPDDR4 memory. This integration eliminates DDR routing complexity, reduces PCB layer count, improves signal integrity, and lowers BOM cost. The AM6254ATLHJAMKR retains identical CPU, GPU, PRU, and peripheral functionality but reassigns DDR-related pins (e.g., VDDS_DDR, DDR_ZQ) to optimized SiP power and calibration roles.
Does AM6254ATLHJAMKR support Time-Sensitive Networking (TSN)?
Yes, AM6254ATLHJAMKR supports TSN via its integrated 2-port Gigabit Ethernet switch, implementing IEEE 1588 Annex D/E/F and 802.1AS Precision Time Protocol (PTP) for sub-microsecond time synchronization. It includes hardware timestamping, scheduled traffic shaping, and priority-based flow control - enabling deterministic networking for industrial automation, robotics, and synchronized control systems without external TSN switches.
What security features are implemented in AM6254ATLHJAMKR?
AM6254ATLHJAMKR implements hardware-enforced Secure Boot with configurable Root-of-Trust (RoT), Arm TrustZone-based Trusted Execution Environment (TEE), firewall-isolated Security Management Subsystem (SMS), Replay Protected Memory Block (RPMB), and dedicated cryptographic accelerators (AES-128/192/256, SHA2-224/256/384/512, PKA, DRBG with TRNG). These features enable secure firmware updates, isolated secure storage, and runtime protection against tampering and side-channel attacks.
Can AM6254ATLHJAMKR drive two independent displays simultaneously?
Yes, AM6254ATLHJAMKR supports dual independent displays at up to 1920×1080@60fps each using its Display Subsystem (DSS). It provides separate PLLs for each display, OLDI (LVDS) and DPI (24-bit RGB) interfaces, and built-in safety features including freeze-frame detection and MISR data validation - making it suitable for safety-critical HMI applications where display redundancy or fault detection is required.
What real-time I/O capabilities does AM6254ATLHJAMKR offer beyond the Cortex-A53 cores?
AM6254ATLHJAMKR includes a dual-core Programmable Real-Time Unit Subsystem (PRUSS) operating at 333MHz, with 16KB program memory and 8KB data memory per PRU (all with SECDED ECC). Each PRU supports cycle-accurate GPIO, UART, I²C, and external ADC control, plus CRC32/16 hardware acceleration. This enables deterministic, low-latency I/O handling - such as LED dimming, contactor control, or sensor interfacing - without burdening the main Cortex-A53 cores.
