Texas Instruments AM5716AABCXEA

Overview

AM5716AABCXEA from Texas Instruments is a high-performance Sitara™ Arm® applications processor featuring a single-core Arm Cortex-A15 CPU, one C66x VLIW DSP core, dual Cortex-M4 coprocessors (IPU1/IPU2), and hardware-accelerated video processing (VPE), designed for industrial HMI, automation control, and embedded vision systems requiring real-time determinism and multimedia capability.

For engineers reviewing the AM5716AABCXEA datasheet, AM5716AABCXEA pinout, AM5716AABCXEA application, or AM5716AABCXEA equivalent, key selection criteria include its 1× C66x DSP configuration (vs. AM5718's 2×), absence of IVA-HD subsystem and HDMI encoder, lack of SGX544 GPU and display pipelines, and support for up to 2GB DDR3-1333 memory with 23 mm × 23 mm FCBGA-760 packaging.

Technical Context

The AM5716AABCXEA implements a heterogeneous multicore architecture: the Cortex-A15 handles OS-level tasks and application logic, while the dedicated C66x DSP executes compute-intensive signal and vision algorithms in parallel; the dual Cortex-M4s manage real-time I/O and industrial protocol stacks independently. Its L3/L4 interconnect enables coherent, low-latency communication between subsystems without software intervention.

Hardware security is enforced via silicon-rooted secure boot with customer-programmable keys (SR 2.1), TrustZone-based Trusted Execution Environment (TEE), cryptographic acceleration for AES-128/192/256, SHA2-224/256/384/512, and secure DMA paths - all available on High-Security (HS) variants like AM5716AABCXEA. The device supports PCIe Gen2 (dual 1-lane or single 2-lane), dual Gigabit Ethernet with switch, and PRU-ICSS for deterministic industrial Ethernet protocols.

Key Specifications

Pinout & Package

AM5716AABCXEA is housed in a 23 mm × 23 mm, 0.8-mm pitch, 760-ball Flip-Chip Ball Grid Array (FCBGA) package. Pin assignments follow TI's standardized ABC variant layout with defined power, ground, I/O voltage domains (VDDS_1.8V, VDDS_3.3V), and ball-specific multiplexing modes (MUXMODE 0–15). Unused balls require specific tie-offs per Table 4-1 (e.g., AE15 to GND via pull resistor; E20 to corresponding supply).

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-performance industrial processor applications.

Compared with AM5718ABCXEA, AM5716AABCXEA reduces cost and power by omitting the second DSP, HDMI, and GPU - making it optimal for cost-sensitive industrial control. Against AM6548ABNPA, it retains legacy C66x compatibility and VPE acceleration but lacks modern safety certifications and ARMv8 instruction set.

FAQ

What distinguishes AM5716AABCXEA from AM5718ABCXEA?

The AM5716AABCXEA contains one C66x DSP core, no IVA-HD subsystem, no HDMI encoder, and no SGX544 GPU - unlike the AM5718ABCXEA which includes two C66x DSPs, full IVA-HD 4K video support, HDMI 1.4a, and GPU. Both share identical Cortex-A15, dual Cortex-M4, VPE, PRU-ICSS, and package. AM5716AABCXEA is optimized for cost and power-constrained industrial control where dual-DSP or display output is unnecessary.

Does AM5716AABCXEA support secure boot and cryptographic acceleration?

Yes, AM5716AABCXEA supports hardware-enforced secure boot with customer-programmable eFuses (Silicon Revision 2.1), AES-128/192/256, SHA2-224/256/384/512, 3DES, MD5, and True Random Number Generation. These features are implemented in dedicated on-die accelerators and are available on High-Security (HS) variants like AM5716AABCXEA - enabling trusted firmware execution and encrypted communications without CPU overhead.

What video capabilities does AM5716AABCXEA provide?

AM5716AABCXEA integrates a Video Processing Engine (VPE) supporting hardware-accelerated scaling, color-space conversion, and deinterlacing for up to 1080p60 video pipelines. It lacks the IVA-HD subsystem found in AM5718, so it does not support H.264 4K encode/decode. Video input is handled via VIP module supporting up to four multiplexed ports, and output is limited to parallel LCD interfaces (VOUT1–VOUT3 are disabled per device comparison table).

Which industrial Ethernet protocols can be implemented on AM5716AABCXEA?

AM5716AABCXEA supports industrial Ethernet protocols via its dual PRU-ICSS subsystems, enabling implementation of EtherCAT, PROFINET IRT, Ethernet/IP, and POWERLINK without external ASICs. Each PRU-ICSS provides 200-MHz RISC cores with local memory and direct access to GPIO, timers, and serial interfaces - allowing sub-microsecond cycle times and deterministic I/O handling required by real-time industrial networks.

What memory interfaces does AM5716AABCXEA support?

AM5716AABCXEA supports DDR3/DDR3L via its External Memory Interface (EMIF) - up to DDR3-1333 (667 MHz) with 2GB address space across a single chip select. It also includes a General-Purpose Memory Controller (GPMC) for NAND/NOR/OneNAND flash, Quad SPI (QSPI) for XIP boot, and eMMC/SD/SDIO interfaces (MMC1–MMC4). On-chip memory consists of 512KB OCMC RAM with ECC for low-latency critical code storage.
