Texas Instruments AM5726BABCXA

Overview

AM5726BABCXA from Texas Instruments is a high-performance Sitara™ Arm applications processor featuring dual Cortex-A15 CPUs, two C66x DSPs, 2.5MB on-chip L3 RAM, dual DDR3/DDR3L memory interfaces supporting up to DDR3-1066, and 247 GPIO pins. It delivers programmable video processing and cryptographic acceleration (AES, SHA, RNG) for industrial HMI and automation systems requiring real-time vision analytics and secure connectivity.

For engineers reviewing the AM5726BABCXA datasheet, AM5726BABCXA pinout, AM5726BABCXA application, or AM5726BABCXA equivalent, key selection considerations include its lack of HDMI, IVA-HD, EVEs, SGX544 GPU, and BB2D hardware acceleration-distinguishing it from AM5728/AM5729-and its fixed 760-pin FCBGA (ABC) package with 23 mm × 23 mm body size and 0.8-mm pitch.

Technical Context

The AM5726BABCXA implements a heterogeneous multicore architecture with dual Arm Cortex-A15 RISC CPUs, two TI C66x VLIW floating-point DSPs, and dual Cortex-M4 coprocessors (IPU1/IPU2), enabling parallel execution of control, signal, and real-time tasks. Its memory subsystem includes two independent EMIF controllers supporting up to 2GB DDR3/DDR3L per interface and 2.5MB on-chip OCMC RAM with ECC.

Peripheral integration includes dual PRU-ICSS for industrial protocol offload, six McASP modules (16+4×4 serializers), four McSPI, five I²C, ten UART, dual DCAN (CAN 2.0B), PCIe gen2 (two 1-lane or one 2-lane port), SATA gen2, USB 3.0/2.0 dual-role, and three VIP modules-all accessible via a high-speed interconnect fabric with EDMA and system DMA support.

Key Specifications

Pinout & Package

AM5726BABCXA uses a 760-ball FCBGA (ABC) package with 23 mm × 23 mm body size and 0.8-mm ball pitch. Ball assignment follows TI's standardized ABC footprint; unused balls (e.g., AF7, AE4, AB26) are NC, while reserved balls (Y5, K14, B28) must remain unconnected. Power and ground balls require dedicated decoupling per TI's recommended layout guidelines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar applications processor applications.

Compared with AM5728BABCXA, AM5726BABCXA removes HDMI, GPU, EVEs, and IVA-HD to reduce BOM cost and thermal load while retaining identical CPU/DSP compute, memory bandwidth, and industrial I/O - making it optimal for headless or LVDS-based automation nodes. Against AM5718BABCXA, it doubles A15 cores and adds full C66x DSPs for demanding signal processing without sacrificing peripheral richness.

FAQ

What is the maximum DDR3 speed supported by AM5726BABCXA?

AM5726BABCXA supports DDR3-1066 operation across both EMIF channels. Each interface can drive up to 2GB of DDR3/DDR3L memory, and the unified L3 memory map allows up to 2GB of interleaved SDRAM space accessible by all initiators including MPU, DSP, and DMA. The device datasheet specifies timing parameters compliant with JEDEC DDR3-1066 standards under recommended operating conditions.

Does AM5726BABCXA include HDMI or GPU functionality?

No, AM5726BABCXA does not include HDMI encoder, SGX544 GPU, BB2D 2D accelerator, or IVA-HD subsystem. These features are explicitly excluded per the AM572x device comparison table. The display subsystem supports only LVDS and parallel RGB outputs via its three video pipelines - making AM5726BABCXA suitable for headless or non-HDMI industrial displays.

How many PRU-ICSS units does AM5726BABCXA have?

AM5726BABCXA includes two fully functional Programmable Real-Time Unit and Industrial Communication SubSystems (PRU-ICSS1 and PRU-ICSS2). Each unit contains dual 32-bit RISC cores, dedicated instruction/data RAM, and programmable I/O registers - enabling deterministic real-time I/O handling, industrial protocol stacks, and custom peripheral emulation without CPU involvement.

What video acceleration capabilities are present in AM5726BABCXA?

AM5726BABCXA integrates the Video Processing Engine (VPE) for hardware-accelerated scaling, color space conversion (YUV↔RGB), and deinterlacing of HD video streams. It lacks Embedded Vision Engines (EVEs), IVA-HD subsystem, and SGX544 GPU - meaning it supports only single-pipeline 1080p60 video processing without 4K encode/decode or computer vision acceleration.

Is AM5726BABCXA pin-compatible with AM5728BABCXA or AM5729BABCXA?

Yes, AM5726BABCXA shares identical 760-pin FCBGA (ABC) package dimensions, ball pitch, and mechanical footprint with AM5728BABCXA and AM5729BABCXA. All three devices use the same ABC package variant, enabling PCB reuse across the AM572x family - though functional differences (e.g., missing HDMI, EVEs, GPU) require software and peripheral design validation.
