Texas Instruments AM5749ABZXA

Overview

AM5749ABZXA from Texas Instruments is a high-performance Sitara™ Arm® applications processor featuring dual Cortex®-A15 CPUs, two C66x DSP cores, dual Cortex-M4 coprocessors, two Embedded Vision Engines (EVEs), and a dual-core PowerVR® SGX544 GPU. It integrates DDR3/DDR3L EMIFs supporting up to DDR3-1333, HDMI 1.4a encoder, PRU-ICSS for industrial Ethernet, and cryptographic acceleration (AES-128/192/256, SHA2-224/256/384/512). It targets industrial HMI, vision analytics, and real-time control systems requiring heterogeneous compute and secure multimedia processing.

For engineers reviewing the AM5749ABZXA datasheet, AM5749ABZXA pinout, AM5749ABZXA application, or AM5749ABZXA equivalent, key selection considerations include its 760-pin FCBGA (ABZ) package, dual EMIF with ECC on EMIF1, IVA-HD subsystem enabling 4K@15fps H.264 encode/decode, and support for CAN FD via MCAN - all critical for deterministic industrial edge computing and embedded vision deployment.

Technical Context

The AM5749ABZXA implements a tightly coupled heterogeneous architecture: dual Cortex-A15 cores handle OS and application layers, while C66x DSPs execute signal-intensive algorithms like video analytics or motor control; EVEs offload computer vision workloads such as feature detection and optical flow. Its IVA-HD subsystem includes dedicated hardware for H.264 and other codecs up to 1080p60, and VPE enables scalable video scaling and composition.

Security is enforced at silicon level: Secure Boot establishes hardware root-of-trust using customer-programmable OTP keys; TrustZone® isolates secure world execution; cryptographic accelerators support AES, SHA2, and TRNG with DMA offload. The dual PRU-ICSS subsystems provide real-time, low-latency industrial protocol stacks (EtherCAT®, Profinet, Ethernet/IP) independent of the main CPU.

Key Specifications

Pinout & Package

AM5749ABZXA uses a 23 mm × 23 mm, 0.8-mm pitch, 760-ball FCBGA (ABZ) package. Pin configuration follows TI's standardized ABZ ball map with defined power, ground, I/O voltage domains (VDD_MPU, VDD_CORE, VDD_DDR, etc.), and multiplexed peripheral signals controlled via pad configuration registers.

FAQ

What is the maximum DDR3 data rate supported by the AM5749ABZXA?

The AM5749ABZXA supports DDR3/DDR3L interfaces up to DDR3-1333 (667 MHz clock, 1333 MT/s data rate) on both EMIF1 and EMIF2. EMIF1 additionally supports ECC for enhanced reliability in mission-critical applications, while EMIF2 operates without ECC. This allows dual-channel memory configurations with up to 2 GB per interface.

Does the AM5749ABZXA support CAN FD, and how is it implemented?

Yes, the AM5749ABZXA supports CAN FD through its dedicated MCAN module, which implements the CAN 2.0B protocol with flexible data-rate extensions. Unlike the two DCAN modules (which support only classical CAN 2.0B), the MCAN module enables payloads up to 64 bytes and bit rates exceeding 1 Mbps - critical for high-speed firmware updates and diagnostics in modern industrial networks.

How does the AM5749ABZXA handle secure boot and cryptographic operations?

The AM5749ABZXA implements hardware-enforced secure boot with a programmable one-time-programmable (OTP) key store, customer-defined keys, and anti-rollback protection. It includes dedicated cryptographic accelerators for AES-128/192/256, SHA2-224/256/384/512, MD5, SHA1, and a true random number generator - all accessible via DMA to offload CPU and meet real-time encryption deadlines without software bottlenecks.

What video codecs and resolutions does the IVA-HD subsystem in the AM5749ABZXA support?

The IVA-HD subsystem in the AM5749ABZXA supports H.264 encode and decode at up to 4K resolution (3840×2160) at 15 fps. For other codecs including MPEG-4, VC-1, and VP8, maximum support is 1080p60. This makes the AM5749ABZXA suitable for high-resolution video surveillance, digital signage, and medical imaging applications requiring hardware-accelerated compression.

Is the AM5749ABZXA pin-compatible with other AM574x variants like AM5748ABZXA?

Yes, the AM5749ABZXA shares identical 760-ball FCBGA (ABZ) packaging, mechanical footprint, and pinout with AM5748ABZXA and AM5746ABZXA. All three devices use the same 23 mm × 23 mm body size and 0.8-mm pitch, enabling PCB reuse across the AM574x family - though functional differences (e.g., missing EVEs or HDMI in lower variants) must be accounted for in firmware and system design.
