Product details
Overview
AM5748ABZXA from Texas Instruments is a high-performance Sitara™ Arm® applications processor featuring dual Cortex®-A15 CPUs, two C66x DSP cores, dual Cortex-M4 coprocessors, and integrated video acceleration (IVA-HD, VPE, EVE). It supports DDR3-1333 memory, HDMI 1.4a output, and dual Gigabit Ethernet for industrial HMI and vision analytics systems.
For engineers reviewing the AM5748ABZXA datasheet, AM5748ABZXA pinout, AM5748ABZXA application, or AM5748ABZXA equivalent, key selection criteria include its 760-pin FCBGA package, dual EMIF with ECC on EMIF1, PRU-ICSS for real-time industrial protocols, and cryptographic acceleration supporting AES-128/192/256 and SHA2-224/256/384/512.
Technical Context
The AM5748ABZXA implements a heterogeneous multicore architecture: dual Cortex-A15 cores handle OS and control tasks, while two C66x DSPs execute compute-intensive signal processing; dual M4 coprocessors manage real-time I/O and safety-critical functions. The IVA-HD subsystem delivers 4K@15fps H.264 encode/decode, and the VPE enables full-HD video scaling and composition.
Its memory subsystem includes 2.5MB on-chip L3 RAM with ECC, two DDR3/DDR3L EMIFs (up to 2GB each, ECC on EMIF1), and GPMC for NAND/NOR/async memory. Connectivity integrates PCIe Gen2 (two 1-lane or one 2-lane port), SATA Gen2, USB 3.0/2.0 dual-role, MCAN-FD, DCAN, and dual PRU-ICSS for EtherCAT/EtherNet/IP offload.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM5749ABZXA | Includes EVE1/EVE2, HDMI, IVA-HD, SGX544 GPU - full feature set vs. AM5748ABZXA's EVE-disabled variant | Required for 4K video analytics or OpenGL ES 2.0 graphics rendering; not needed for pure HMI or protocol gateway use | Select AM5749ABZXA only when EVE or HDMI functionality is mandatory; AM5748ABZXA offers identical CPU/DSP/PRU/EMIF performance at lower cost |
| AM5746ABZXA | Lacks EVE, HDMI, IVA-HD, SGX544 GPU, and VOUT1–VOUT3 - reduced multimedia capability but same MPU/DSP/PRU/EMIF foundation | Suitable for headless industrial controllers or gateways where video processing is unnecessary | Choose AM5746ABZXA for cost-sensitive embedded control applications without vision or display requirements |
Compared with AM5749ABZXA, AM5748ABZXA removes EVE and HDMI while retaining identical dual A15/C66x/PRU/EMIF capabilities - making it optimal for non-4K vision or non-HDMI HMI designs. Versus AM5746ABZXA, AM5748ABZXA adds VPE and video pipelines for full-HD processing, enabling richer UIs without external video ICs.

EMIF1 supports ECC for enhanced reliability in industrial control applications, while EMIF2 provides additional memory bandwidth for video frame buffers or large application workloads. Both channels support up to 2 GB of DDR3/DDR3L SDRAM.
Does AM5748ABZXA include hardware cryptographic acceleration?
Yes, AM5748ABZXA includes dedicated cryptographic acceleration engines supporting AES-128/192/256, 3DES-56/112/168, SHA1, MD5, and SHA2-224/256/384/512. It also features a true random number generator and DMA-assisted crypto operations - enabling secure boot, encrypted communication, and trusted execution environment (TEE) implementation without CPU overhead.
How many PRU-ICSS units does AM5748ABZXA have, and what are their roles?
AM5748ABZXA contains two independent Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) units. Each PRU-ICSS provides dual 32-bit RISC cores with direct access to peripherals like Ethernet MAC, GPIO, and UART. They enable deterministic real-time protocol stacks including EtherCAT, PROFINET, and Ethernet/IP - offloading time-critical tasks from the ARM A15 cores.
What video codecs and resolutions does AM5748ABZXA support through its IVA-HD subsystem?
The AM5748ABZXA's IVA-HD subsystem supports H.264 encode and decode at 4K resolution (3840×2160) at 15 fps, and other codecs (MPEG-4, VC-1, VP8) up to 1080p60. It also integrates the Video Processing Engine (VPE) for scaling, deinterlacing, and color space conversion - enabling full-HD video playback and multi-stream processing in a single chip.
Is AM5748ABZXA pin-compatible with other AM574x variants like AM5749ABZXA or AM5746ABZXA?
Yes, AM5748ABZXA is pin-compatible with AM5749ABZXA and AM5746ABZXA in the 760-ball FCBGA (ABZ) package. All three share identical mechanical footprint, power delivery requirements, and ball-level signal mapping. Functional differences (e.g., EVE presence, HDMI support) are implemented internally and do not affect PCB layout or interconnect design.
