Texas Instruments AM5726BABCXAR

Overview

AM5726BABCXAR from Texas Instruments is a high-performance Sitara™ Arm applications processor featuring dual Cortex-A15 CPUs, two C66x DSPs, two Cortex-M4 coprocessors, and a Vision AccelerationPac with four Embedded Vision Engines (EVEs). It integrates dual DDR3/DDR3L memory interfaces supporting up to DDR3-1066, 2.5MB on-chip L3 RAM, PCIe Gen2, SATA Gen2, dual Gigabit Ethernet, and extensive industrial connectivity including dual DCAN, PRU-ICSS, and 247 GPIO - deployed in industrial HMIs, automation gateways, and embedded vision analytics systems.

For engineers reviewing the AM5726BABCXAR datasheet, AM5726BABCXAR pinout, AM5726BABCXAR application, or AM5726BABCXAR equivalent, key selection considerations include its lack of HDMI, IVA-HD, SGX544 GPU, BB2D 2D accelerator, and EVE support compared to AM5728/AM5729 - making it optimized for cost-sensitive, non-video-intensive real-time control and communication workloads requiring deterministic I/O and multi-core programmability.

Technical Context

The AM5726BABCXAR implements a heterogeneous multicore architecture with dual Cortex-A15 cores running at up to 1.5 GHz, two C66x VLIW DSPs for signal processing, and two Cortex-M4 coprocessors (IPU1/IPU2) for real-time control tasks. Its memory subsystem includes two independent EMIF controllers supporting up to 2GB DDR3/DDR3L per channel and 2.5MB on-chip OCMC RAM with ECC.

Peripheral integration centers on industrial communication: dual DCAN modules compliant with CAN 2.0B, two PRU-ICSS subsystems for protocol offload (EtherCAT, PROFIBUS), 10 UARTs, 5 I²C ports, 4 McSPI, QSPI, GPMC, and 16 general-purpose timers - all mapped to 247 GPIO pins in a 760-ball FCBGA package with 0.8-mm pitch and 23 mm × 23 mm body size.

Key Specifications

Pinout & Package

AM5726BABCXAR uses a 760-ball Fine-Pitch Ball Grid Array (FCBGA) package with 23 mm × 23 mm body size and 0.8-mm ball pitch. The package supports 247 configurable GPIO pins across multiple voltage domains (1.8 V, 3.3 V), with dedicated power/ground balls, decoupling capacitor pads (e.g., cap_vbbldo_mpu, cap_vddram_core1), and reserved/unconnected balls explicitly defined in TI documentation.

Equivalent & Alternatives

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

Compared with AM5728BABCXAR, AM5726BABCXAR removes video subsystems to reduce cost and power while retaining identical CPU/DSP/M4/PRU-ICSS compute and industrial I/O - making it optimal for headless control. Versus AM5718BABCXAR, it delivers full dual-A15 performance and dual-PRU-ICSS redundancy for mission-critical infrastructure.

AM5726BABCXAR is available at Aetrix Electronics and suitable for industrial HMIs, PLC edge nodes, smart energy controllers, and ruggedized IoT gateways requiring stable component supply across extended product lifecycles.

Supply support for AM5726BABCXAR includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, delivering analog and embedded processing solutions for industrial, automotive, and communications markets since 1930.

The AM572x Sitara™ processor family was designed to address high-performance, real-time industrial applications - combining Arm application processing, DSP acceleration, and programmable real-time subsystems in a single chip for deterministic control and protocol flexibility.

FAQ

Does AM5726BABCXAR support HDMI or video encoding/decoding?

No, AM5726BABCXAR does not support HDMI, IVA-HD, SGX544 GPU, or Embedded Vision Engines (EVEs). These features are explicitly excluded per TI's Device Comparison Table (SPRS953G Rev G, Table 3-1). The AM5726BABCXAR is intended for headless industrial control applications where video subsystems are unnecessary - unlike AM5728/AM5729 which include full display and video acceleration capabilities.

What is the maximum DDR3 speed supported by AM5726BABCXAR?

AM5726BABCXAR supports DDR3/DDR3L memory up to DDR3-1066 (533 MHz data rate) per EMIF channel, with up to 2 GB addressable space per interface. This is confirmed in Section 1.1 Features and Table 5-5 Operating Performance Points of the SPRS953G datasheet. System-level bandwidth depends on interleaving configuration across both EMIFs.

How many PRU-ICSS subsystems does AM5726BABCXAR include?

AM5726BABCXAR includes two fully functional Programmable Real-Time Unit and Industrial Communication SubSystems (PRU-ICSS1 and PRU-ICSS2), as verified in Table 3-1 Device Comparison and Section 1.1 Features. Each PRU-ICSS provides dual 32-bit RISC cores, programmable I/O, and hardware accelerators for industrial protocols including EtherCAT, PROFINET, and EnDat.

Is AM5726BABCXAR pin-compatible with AM5728BABCXAR or AM5729BABCXAR?

Yes, AM5726BABCXAR shares identical 760-ball FCBGA (ABC) packaging, mechanical footprint, and pinout with AM5728BABCXAR and AM5729BABCXAR - confirmed in Device Information Table (Section 1.2) and Mechanical Packaging documentation. However, functional differences exist: AM5726 lacks HDMI, GPU, IVA-HD, EVEs, and BB2D, so software and peripheral design must account for these omissions.

What cryptographic accelerators are integrated into AM5726BABCXAR?

AM5726BABCXAR integrates hardware crypto accelerators for AES (128/192/256-bit), SHA-1/SHA-2 (224/256/384/512), RNG (NIST SP800-90 compliant), DES, and 3DES - as stated in Section 1.1 Features. These engines support secure boot, encrypted filesystems, and TLS 1.2+ offload, enabling compliance with IEC 62443-3-3 for industrial cybersecurity.
