Texas Instruments AM5716AABCDEA

Overview

AM5716AABCDEA from Texas Instruments is a high-performance Sitara™ applications processor integrating an Arm® Cortex®-A15 CPU, one C66x VLIW DSP core, dual Arm® Cortex®-M4 coprocessors (IPU1/IPU2), and a Vivante® GC320 2D accelerator. It supports DDR3-1333 memory, HDMI 1.4a output, dual Gigabit Ethernet, PCIe Gen2, and up to 215 GPIOs - deployed in industrial HMIs, automation controllers, and embedded vision gateways.

For engineers reviewing the AM5716AABCDEA datasheet, AM5716AABCDEA pinout, AM5716AABCDEA application, or AM5716AABCDEA equivalent, key selection criteria include its single-C66x DSP configuration (vs. dual on AM5718), absence of IVA-HD video encode/decode, lack of HDMI and SGX544 GPU, and silicon revision 2.0/2.1 security feature support - all critical for secure industrial edge compute designs.

Technical Context

The AM5716AABCDEA implements a heterogeneous multicore architecture: the Cortex-A15 handles OS-level control and application tasks, while the dedicated C66x DSP executes real-time signal processing algorithms with up to 32 × 16-bit fixed-point multiplies per cycle. Its L3/L4 interconnect enables coherent data movement between MPU, DSP, M4s, and accelerators like BB2D and VPE.

Hardware security is enforced via silicon-rooted secure boot (customer-programmable keys), TrustZone-based TEE, cryptographic acceleration (AES-128/192/256, SHA2-224/256/384/512), and secure debug access - all confirmed for High-Security (HS) variants. The device uses 28-nm CMOS and targets AEC-Q100 qualification.

Key Specifications

Pinout & Package

AM5716AABCDEA is housed in a 23 mm × 23 mm, 0.8-mm pitch, 760-ball FCBGA (FCBGA-N760) package. Ball assignment follows TI's standardized layout with reserved, unused, and power/ground balls explicitly defined in datasheet Section 4.1. Pin functions are multiplexed across 16 modes, with MUXMODE 0 as primary mapping.

FAQ

What is the maximum DDR3 speed supported by AM5716AABCDEA?

The AM5716AABCDEA supports DDR3/DDR3L memory at up to 1333 MT/s (667 MHz clock), with a 32-bit EMIF interface capable of addressing up to 2 GB across a single chip select. This bandwidth sustains concurrent operation of Linux OS, real-time control tasks on Cortex-M4s, and video processing on the VPE - verified in TI's AM5716 ICE evaluation platform under OPP_HIGH conditions.

Does AM5716AABCDEA include hardware video encoding capability?

No, AM5716AABCDEA does not include the IVA-HD subsystem and therefore lacks hardware-accelerated H.264 or other video codec encoding/decoding. It supports only video processing functions via the VPE (scaling, color space conversion) and BB2D (2D graphics composition). For encode/decode, external codecs or software-based solutions are required - unlike the AM5718AABCDEA which integrates full IVA-HD.

Is AM5716AABCDEA pin-compatible with AM5718AABCDEA?

Yes, AM5716AABCDEA and AM5718AABCDEA share identical 760-ball FCBGA packaging, mechanical footprint, and ball assignment - enabling PCB layout reuse. However, functional differences (e.g., missing IVA-HD, HDMI, SGX544 GPU, second C66x DSP) require careful software and peripheral validation before drop-in substitution.

What security features are implemented in AM5716AABCDEA silicon revision 2.1?

AM5716AABCDEA silicon revision 2.1 includes hardware-enforced secure boot with customer-programmable keys, TrustZone-based Trusted Execution Environment (TEE), cryptographic acceleration (AES-128/192/256, SHA2-224/256/384/512, 3DES), true random number generation, and secure debug access - all documented in SPRS957I Revision I datasheet Section 1.1 and confirmed for High-Security (HS) variants.

Which industrial Ethernet protocols are supported natively by AM5716AABCDEA?

AM5716AABCDEA supports EtherCAT®, Ethernet/IP, and Profinet natively through its dual PRU-ICSS subsystems - each PRU-ICSS contains dual 32-bit RISC cores, programmable I/O, and dedicated Ethernet MAC/PHY interfaces. TI provides certified protocol stacks and reference implementations validated for real-time determinism down to 100 µs cycle times.
