Product details
Overview
AM5748ABZX 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 delivers 4K@15fps H.264 encode/decode, dual DDR3L-1333 interfaces with ECC on EMIF1, and supports industrial HMI, automation gateways, and embedded vision systems.
For engineers reviewing the AM5748ABZX datasheet, AM5748ABZX pinout, AM5748ABZX application, or AM5748ABZX equivalent, key selection criteria include its 760-pin FCBGA package, dual-core A15 + dual C66x architecture, 2.5MB on-chip L3 RAM, PCIe Gen2 dual-lane support, and hardware-accelerated cryptographic engines (AES-128/192/256, SHA2-224/256/384/512).
Technical Context
The AM5748ABZX implements a heterogeneous multicore architecture where Cortex-A15 cores handle OS-level control and application tasks, while C66x DSPs execute real-time signal processing and analytics; IPU1/IPU2 (Cortex-M4) manage low-latency industrial I/O and PRU-ICSS handles deterministic Ethernet protocol stacks.
Its memory subsystem integrates two independent DDR3/DDR3L EMIF controllers (up to 2GB each, DDR3-1333), 2.5MB OCMC RAM with ECC, GPMC for NAND/NOR, and DMA paths secured via TrustZone®-enforced isolation-enabling concurrent high-bandwidth video streaming, secure boot, and real-time control in a single SoC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM5749ABZX | Includes EVE1/EVE2 and HDMI; higher base PN register value (0x5C vs 0x5A); identical package and pinout | Required for full 4K video analytics and HDMI output; not needed if only 1080p and no EVE offload | Select AM5749ABZX when EVE-based vision acceleration or HDMI output is mandatory |
| AM5728ABZX | Single Cortex-A15 core, no EVE, no HDMI, reduced DDR bandwidth (DDR3L-1066), same 760-pin ABZ package | Suitable for cost-sensitive HMIs and gateways without 4K/video acceleration; lower thermal envelope | Choose AM5728ABZX for simpler industrial control applications where dual A15 and EVE are unnecessary |
Compared with AM5749ABZX, AM5748ABZX omits EVE and HDMI but retains identical CPU/DSP/PRU-ICSS performance and security features; versus AM5728ABZX, it adds a second A15 core, DDR3L-1333, and full IVA-HD-making it optimal for scalable vision-enabled edge devices requiring both control and analytics.

FAQ
What is the maximum DDR3L speed supported by AM5748ABZX?
AM5748ABZX supports DDR3L-1333 (667 MHz) on both EMIF1 and EMIF2, with ECC enabled only on EMIF1. This allows up to 2GB per channel and interleaved access for high-bandwidth video and analytics workloads. The device's memory controller complies with JEDEC DDR3L standards and requires proper board-level termination and layout per TI's AM574x DDR3 Layout Guidelines.
Does AM5748ABZX support CAN FD?
Yes, AM5748ABZX supports CAN FD through its MCAN module, which implements the CAN 2.0B protocol with flexible data-rate capability. DCAN1 and DCAN2 also support standard CAN 2.0B. MCAN functionality is enabled via pin multiplexing options documented in the AM574x Technical Reference Manual, and requires appropriate software configuration of the MCAN controller registers.
What security features are implemented in AM5748ABZX?
AM5748ABZX includes hardware-enforced secure boot with customer-programmable OTP keys, AES-128/192/256 and SHA2-224/256/384/512 cryptographic acceleration, True Random Number Generator, TrustZone-based Trusted Execution Environment (TEE), and secure debug access controls. These features are fully implemented in all AM5748ABZX devices-not limited to HS variants-enabling secure firmware updates and data confidentiality in industrial deployments.
How many PRU-ICSS instances does AM5748ABZX integrate?
AM5748ABZX integrates two independent Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) modules-PRU-ICSS1 and PRU-ICSS2-each containing dual 32-bit RISC cores, local instruction/data RAM, and dedicated peripherals for industrial Ethernet, encoder/decoder, and custom real-time I/O. Both PRU-ICSS units are fully functional and pin-compatible across the AM574x family.
Is AM5748ABZX pin-compatible with AM5746ABZX?
Yes, AM5748ABZX is pin-compatible with AM5746ABZX in the 760-ball FCBGA (ABZ) package. Both share identical mechanical dimensions, ball pitch, and signal mapping. However, AM5748ABZX enables additional features-including EVE, HDMI, IVA-HD, and SGX544 GPU-that are disabled or absent in AM5746ABZX. Functional compatibility depends on enabling only the shared peripherals in software.
