Product details
Overview
AM5749ABZXEA 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, and hardware-accelerated cryptographic engines (AES-128/192/256, SHA2-224/256/384/512). It targets industrial HMI, vision-enabled automation, and analytics edge nodes requiring real-time video processing and secure boot.
For engineers reviewing the AM5749ABZXEA datasheet, AM5749ABZXEA pinout, AM5749ABZXEA application, or AM5749ABZXEA equivalent, key selection considerations include its 760-pin FCBGA package, dual EMIF with ECC on EMIF1, IVA-HD subsystem for 4K@15fps H.264 encode/decode, PRU-ICSS for industrial protocol offload, and HS-device security features including TrustZone®-based TEE and OTP-programmable keys.
Technical Context
The AM5749ABZXEA implements a heterogeneous multicore architecture where Cortex-A15 cores handle OS and control tasks, C66x DSPs execute compute-intensive signal and vision algorithms, and EVEs accelerate computer vision workloads like feature detection and optical flow. Its IVA-HD subsystem includes dedicated hardware for H.264 and other codecs up to 1080p60, while the VPE handles video scaling and composition.
Security is enforced via hardware root-of-trust: secure boot verifies signed images using customer-programmable OTP keys, TrustZone® isolates secure world execution, and cryptographic accelerators offload AES, SHA2, and TRNG operations with DMA support. The device supports two independent PRU-ICSS subsystems for deterministic real-time Ethernet protocol stacks (e.g., EtherCAT®, Profinet) without CPU intervention.

FAQ
What is the maximum DDR3 speed supported by AM5749ABZXEA?
The AM5749ABZXEA supports DDR3/DDR3L rates up to DDR3-1333 (667 MHz clock, 1333 MT/s data rate) on both EMIF1 and EMIF2. EMIF1 supports ECC for enhanced reliability in mission-critical applications, while EMIF2 operates without ECC. Layout must comply with JEDEC DDR3 specifications including trace length matching and termination.
Does AM5749ABZXEA support CAN FD?
Yes, AM5749ABZXEA includes one Modular Controller Area Network (MCAN) module that supports CAN FD (Flexible Data Rate) functionality in addition to standard CAN 2.0B. This capability is confirmed in the device comparison table and functional description. The MCAN module enables higher bandwidth and larger payload sizes for modern automotive and industrial networks.
What security features are enabled on AM5749ABZXEA versus AM5748ABZXEA?
AM5749ABZXEA, as a High-Security (HS) device, enables full secure boot with customer-programmable OTP keys, TrustZone®-based Trusted Execution Environment (TEE), debug security, and hardware firewalls. These features are documented as available only on HS devices-including AM5749ABZXEA-while AM5748ABZXEA lacks HS-specific security capabilities despite sharing many peripherals.
How many video input channels does AM5749ABZXEA support?
AM5749ABZXEA supports up to eight multiplexed video input ports via two Video Input Port (VIP) modules (VIP1 and VIP2). Each VIP module accepts four differential pairs (vin1a/b through vin4a/b), enabling simultaneous capture from multiple cameras or sensors. This capability is explicitly stated in Section 1.1 Features and confirmed in Table 3-1 Device Comparison.
Is AM5749ABZXEA pin-compatible with AM5746ABZXEA?
No, AM5749ABZXEA is not pin-compatible with AM5746ABZXEA. While both use the same 760-pin ABZ package, Table 3-1 shows AM5746ABZXEA omits critical functions present on AM5749ABZXEA-including EVE1/EVE2, HDMI, IVA-HD, SGX544 GPU, and VOUT1–VOUT3-and has different pinmux configurations. Direct substitution would require PCB redesign and firmware adaptation.
