Product details
Overview
AM5718AABCXA from Texas Instruments is a high-performance Sitara™ Arm® applications processor featuring a single-core Arm Cortex-A15 CPU, dual C66x VLIW DSP cores, dual Cortex-M4 coprocessors (IPU1/IPU2), IVA-HD video subsystem supporting 4K@15fps H.264 encode/decode, PowerVR SGX544 3D GPU, and PRU-ICSS for real-time industrial communication - deployed in industrial HMIs, automation gateways, and embedded vision systems.
For engineers reviewing the AM5718AABCXA datasheet, AM5718AABCXA pinout, AM5718AABCXA application, or AM5718AABCXA equivalent, key selection considerations include DDR3-1333 support (667 MHz), 760-pin FCBGA package with 23 mm × 23 mm body, 512KB on-chip L3 RAM, PCIe Gen2 dual-lane capability, and hardware-accelerated cryptographic engines (AES-128/192/256, SHA2-224/256/384/512).
Technical Context
The AM5718AABCXA integrates heterogeneous processing resources: the Cortex-A15 handles OS-level control and application tasks, while the C66x DSP executes compute-intensive vision/audio algorithms; the dual M4 coprocessors offload real-time I/O and motion control, and the PRU-ICSS enables deterministic Ethernet protocol stacks (EtherCAT, Profinet) without CPU intervention.
Its memory subsystem includes a 32-bit DDR3/DDR3L EMIF supporting up to 2GB across one chip select, 512KB on-chip OCMC RAM with ECC, GPMC for NAND/NOR/async memory, and DMA paths secured via TrustZone-aware EDMA and System DMA - all coordinated by L3/L4 interconnects with firewall-protected masters and slaves.

Pinout & Package
AM5718AABCXA uses a 23 mm × 23 mm, 0.8-mm pitch, 760-ball FCBGA (FCBGA-N760) package. Ball assignment follows TI's standardized ABC variant layout with dedicated power/ground arrays, differential clock pairs, and configurable I/O banks supporting multiple voltage domains (1.8V, 3.3V). Unused balls are defined per Table 4-1 of SPRS957I - including mandatory GND or supply tie-offs for specific reserved balls (e.g., AE15, D20, V27).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance heterogeneous processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM5728AABCXA | Same silicon revision (2.1), identical pinout and peripheral set, but rated for extended temperature range (–40°C to 105°C vs. –40°C to 90°C for AM5718AABCXA). | Required for outdoor or under-hood industrial deployments where ambient exceeds 90°C junction limit. | Select AM5728AABCXA when operating in extended thermal environments; software and hardware design are fully interchangeable. |
| AM6548ABNPA | ARM Cortex-A53 quad-core (1.1 GHz), no C66x DSP, adds ARM Neon and SMMU, supports DDR4, PCIe Gen3, and higher functional safety (ISO 26262 ASIL-B ready). | Targets automotive ADAS domain controllers and safety-critical industrial motion controllers needing ASIL-B compliance. | Choose AM6548ABNPA only when functional safety certification or DDR4 migration is mandatory; not software-compatible with AM5718AABCXA. |
Compared with AM5728AABCXA, AM5718AABCXA offers identical performance and feature set at lower thermal rating - ideal for cost-sensitive, convection-cooled industrial enclosures. Versus AM6548ABNPA, AM5718AABCXA retains legacy C66x DSP compatibility and lower power envelope, but lacks ASIL-B support and DDR4 capability.

FAQ
What is the maximum DDR3 speed supported by AM5718AABCXA?
The AM5718AABCXA supports DDR3/DDR3L memory up to 1333 MT/s (667 MHz), enabling up to 2GB capacity across a single chip select. This speed is validated per JEDEC JESD79-3F specification and requires precise PCB layout with matched trace lengths and proper termination. The EMIF module includes dynamic calibration logic to compensate for voltage and temperature drift during operation.
Does AM5718AABCXA include hardware cryptographic acceleration?
Yes, AM5718AABCXA integrates dedicated cryptographic acceleration engines supporting AES-128/192/256, 3DES-56/112/168, SHA-1, SHA2-224/256/384/512, MD5, and a true random number generator - all accessible via DMA and protected by TrustZone isolation. These accelerators offload encryption/decryption from the Cortex-A15 core, reducing latency for secure boot, TLS, and IP protection workflows.
How many PRU-ICSS subsystems does AM5718AABCXA contain?
AM5718AABCXA contains two independent Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) modules - PRU-ICSS1 and PRU-ICSS2 - each with dual 200-MHz RISC cores, 12KB local RAM, and direct access to peripherals including EMIF, GPMC, UART, McSPI, and GPIO. They are used for deterministic real-time tasks such as EtherCAT slave stacks, PWM generation, and encoder interfacing.
Is AM5718AABCXA pin-compatible with AM5728AABCXA?
Yes, AM5718AABCXA and AM5728AABCXA share identical 760-ball FCBGA package dimensions, pinout, and signal mapping - including power, ground, DDR, and peripheral ball assignments. The only difference is thermal rating: AM5728AABCXA is qualified for –40°C to 105°C operation, while AM5718AABCXA is rated for –40°C to 90°C. No PCB redesign is needed for migration.
What video codecs does the IVA-HD subsystem in AM5718AABCXA support?
The IVA-HD subsystem in AM5718AABCXA supports H.264 encode and decode at up to 4K resolution @ 15 fps, plus other codecs including MPEG-4, VC-1, and VP8 at up to 1080p60.
