Product details
Overview
AM5716AABCXA from Texas Instruments is a high-performance Sitara™ Arm® applications processor featuring a single-core Cortex®-A15 CPU, one C66x VLIW DSP core, dual Cortex®-M4 coprocessors (IPU1/IPU2), and integrated peripherals including dual Gigabit Ethernet, PCIe Gen2, USB 3.0/2.0, SATA Gen2, and 215 GPIOs. It supports DDR3-1333 memory, HDMI 1.4a output, and real-time industrial communication via two PRU-ICSS subsystems - deployed in HMI, industrial gateways, and programmable logic controllers.
For engineers reviewing the AM5716AABCXA datasheet, AM5716AABCXA pinout, AM5716AABCXA application, or AM5716AABCXA equivalent, key selection criteria include its single-C66x DSP configuration (vs. dual in AM5718), absence of IVA-HD video encode/decode, lack of HDMI and SGX544 GPU, and support for only one VIP input port - critical for deterministic real-time control and secure industrial edge processing.
Technical Context
The AM5716AABCXA implements a heterogeneous multicore architecture with tightly coupled interconnects (L3/L4), enabling concurrent execution across Arm A15 (control), C66x DSP (signal processing), and dual M4 coprocessors (real-time I/O handling). Its PRU-ICSS subsystems provide deterministic low-latency peripheral control independent of the main CPU.
It integrates dedicated accelerators including BB2D (Vivante GC320) for 2D graphics, VPE for video preprocessing, and cryptographic engines supporting AES-128/192/256, SHA2-224/256/384/512, and TRNG - all accessible via secure DMA paths under TrustZone®-enforced TEE isolation on High-Security (HS) variants.

Pinout & Package
AM5716AABCXA uses a 760-ball FCBGA package (23 mm × 23 mm, 0.8-mm pitch) with power/ground ball mapping defined per TI SPRS957I Section 4.1–4.2. Unused balls require specific tie-offs: AE15/AC15/AE14 must connect to GND via external pull resistors; E20/D21/E23 must connect to corresponding power rails; K14 (vpp) must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AB17 (rtc_porz) | RTC Power-On Reset | Must be tied to VSS when RTC unused; optional connection to PORZ with level translation if RTC enabled. |
| AF14 (rtc_iso) | RTC Isolation Control | Requires external pull to corresponding power rail if unused; may connect to PORZ (F22) when RTC disabled. |
| F22 (porz) | Power-On Reset Output | Active-low reset assertion signal; drives external system reset chain and internal warm reset (SYS_WARM_OUT_RST). |
| Y15–Y16, U18–U28, etc. | Unused/Reserved Balls | Y15/Y16/U18–U28 are unconnected; A27/Y5/Y10/B28 are reserved and must remain unconnected. |
Key Features

FAQ
What distinguishes AM5716AABCXA from AM5718AABCXA in industrial control applications?
The AM5716AABCXA omits the second C66x DSP core, IVA-HD video subsystem, HDMI encoder, SGX544 GPU, and second VIP port present in AM5718AABCXA. This reduces thermal design complexity and BOM cost while retaining identical PRU-ICSS, dual Ethernet, PCIe Gen2, and cryptographic acceleration - making AM5716AABCXA optimal for deterministic control where video processing is unnecessary.
Does AM5716AABCXA support secure boot and cryptographic acceleration in all variants?
Yes, AM5716AABCXA includes hardware cryptographic acceleration (AES-128/192/256, SHA2, TRNG) across all variants. However, full secure boot with customer-programmable keys and anti-rollback protection requires High-Security (HS) silicon revision 2.1 - standard commercial variants support basic secure boot but lack SR 2.1 key programming capability.
Can AM5716AABCXA directly replace AM5718AABCXA on an existing PCB layout?
No, AM5716AABCXA is not a pin-compatible drop-in replacement for AM5718AABCXA. While both use the same 760-ball FCBGA package, differences in power sequencing requirements, unused ball tie-offs (e.g., AM5716 lacks HDMI-related signals), and thermal dissipation profiles necessitate board-level validation - particularly for VDDS_DDR, VDD_MPU, and VDD_CORE rail stability.
What real-time industrial protocols are supported natively by AM5716AABCXA's PRU-ICSS?
AM5716AABCXA's dual PRU-ICSS subsystems support EtherCAT® slave, PROFINET IRT slave, Ethernet/IP adapter, and POWERLINK node implementations via TI's Industrial Communications Engine (ICE) software stack. These run independently of the Arm A15 core, ensuring sub-100 µs cycle times and deterministic I/O response without OS scheduling interference.
Is DDR3 ECC memory supported by AM5716AABCXA's EMIF controller?
Yes, AM5716AABCXA's DDR3/DDR3L External Memory Interface (EMIF) supports ECC operation in x8 or x16 configurations - validated with Micron MT41K256M16TW-107 and Samsung K4B4G1646Q-HYK0 DDR3L devices. ECC correction is handled transparently by hardware, with error logging accessible via the DMM module for system-level fault reporting.
