Product details
Overview
AM5746ABZXA from Texas Instruments is a high-performance Sitara™ Arm® applications processor featuring dual Cortex®-A15 CPUs, two C66x DSP cores, 2.5MB on-chip L3 RAM, dual DDR3/DDR3L EMIFs supporting up to DDR3-1333, and integrated PRU-ICSS for industrial communication. It delivers deterministic real-time control and vision processing in HMI, automation, and analytics systems.
For engineers reviewing the AM5746ABZXA datasheet, AM5746ABZXA pinout, AM5746ABZXA application, or AM5746ABZXA equivalent, key selection criteria include its lack of HDMI, EVE, IVA-HD, SGX544 GPU, and BB2D acceleration-distinguishing it from AM5748/AM5749-and its confirmed support for dual 1-lane PCIe Gen2, MCAN-FD, dual Gigabit Ethernet, and 247 GPIOs in the 760-pin FCBGA (ABZ) package.
Technical Context
The AM5746ABZXA implements a heterogeneous multi-core architecture with tightly coupled memory subsystems: dual Cortex-A15 cores handle OS-level tasks and application logic, while C66x DSPs execute signal- and vision-intensive algorithms. Its PRU-ICSS subsystem provides deterministic low-latency I/O control independent of the main CPU.
Memory hierarchy includes 2.5MB OCMC RAM with ECC, two DDR3/DDR3L interfaces (EMIF1 with ECC, EMIF2 without), and GPMC for NAND/NOR/async memory. Connectivity integrates MCAN-FD, DCAN, USB 3.0/2.0 dual-role, SATA Gen2, PCIe Gen2 (two 1-lane ports), and eight McASP modules for multichannel audio.

Pinout & Package
AM5746ABZXA uses a 23 mm × 23 mm, 0.8-mm pitch, 760-ball FCBGA (ABZ) package. Pin functions are defined across 13 multiplexing modes per ball, with MUXMODE 0 as the primary configuration. Ball reset states include drive-0, drive-1, high-impedance (OFF), pulldown (PD), and pullup (PU); unused pins require explicit software disable of RX buffers and internal pulls.

| emif1_ck/emif1_nck | DDR3 Clock Pair (EMIF1) | Differential clock input driving DDR3 SDRAM timing; critical for setup/hold compliance at DDR3-1333 |
| pru0_r30/pru0_r31 | PRU-ICSS General-Purpose I/O | Dedicated real-time I/O pins for bit-banged protocols or hardware synchronization signals |
| mcasp0_axr0/mcasp0_ahclkr | McASP Serial Audio Data/Clock | Configurable as transmit/receive data line or bit clock; supports TDM/I2S with programmable frame sync |
| pcie1_clkreqn/pcie2_clkreqn | PCIe Active-State Power Management | Per-port CLKREQ# inputs enabling ASPM L0s/L1 entry; required for low-power PCIe link states |

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM5748ABZXA | Includes HDMI 1.4a encoder, dual-core SGX544 GPU, BB2D graphics accelerator, and IVA-HD subsystem - absent in AM5746ABZXA | Required for full-HD display output and hardware video encode/decode (H.264 up to 4K@15fps) | Select AM5748ABZXA when display subsystem and multimedia acceleration are mandatory; AM5746ABZXA reduces cost and power where they are unnecessary |
| AM5728ABZXA | Single Cortex-A15 core, no C66x DSP, no EVE, no PRU-ICSS - lower performance and reduced real-time capability | Suitable for cost-sensitive HMIs without vision analytics or industrial protocol offload | Choose AM5728ABZXA only if application fits within single A15 core and does not require DSP or PRU-ICSS; AM5746ABZXA provides guaranteed dual-core scalability and deterministic I/O |
Compared with AM5748ABZXA, AM5746ABZXA removes display and multimedia accelerators to reduce silicon area and power, making it optimal for headless industrial controllers. Against AM5728ABZXA, AM5746ABZXA adds a second A15 core, two C66x DSPs, and dual PRU-ICSS - essential for concurrent control, analytics, and protocol stack execution.

FAQ
What is the maximum DDR3 speed supported by AM5746ABZXA?
AM5746ABZXA supports DDR3/DDR3L interfaces up to DDR3-1333 (667 MHz clock). Both EMIF1 and EMIF2 support this rate, with EMIF1 providing optional ECC protection for system-critical memory regions. The device's memory controller complies with JEDEC JESD79-3F specifications and requires proper PCB layout per TI's DDR3 design guidelines.
Does AM5746ABZXA include hardware cryptographic acceleration?
Yes, AM5746ABZXA includes dedicated cryptographic acceleration engines supporting AES-128/192/256, 3DES, SHA1, SHA2 (224/256/384/512), MD5, and a true random number generator (TRNG). These accelerators operate independently of the CPU cores and support DMA-driven data transfers, enabling high-throughput secure boot, encrypted storage, and TLS offload without compromising application performance.
How many PCIe lanes does AM5746ABZXA provide, and what configurations are supported?
AM5746ABZXA provides two 5-Gbps PCIe Gen2 lanes configurable as either one 2-lane port or two independent 1-lane ports. This flexibility allows direct connection to a single x2 endpoint (e.g., FPGA or NVMe SSD) or simultaneous interfacing with two separate peripherals such as a protocol-offload FPGA and a wireless module - both operating concurrently without bandwidth sharing.
Is AM5746ABZXA pin-compatible with AM5748ABZXA or AM5749ABZXA?
Yes, AM5746ABZXA is pin-compatible with AM5748ABZXA and AM5749ABZXA in the same 760-pin ABZ FCBGA package. All three share identical mechanical dimensions, ball map, and power/ground pin assignments. However, functional differences exist: AM5746ABZXA omits HDMI, EVE, IVA-HD, SGX544 GPU, and BB2D blocks, meaning those pins are reserved or repurposed - requiring careful review of the Pin Attributes table before PCB reuse.
What industrial communication protocols are natively supported by AM5746ABZXA?
AM5746ABZXA natively supports MCAN with Flexible Data Rate (FD), two DCAN 2.0B modules, dual PRU-ICSS for EtherCAT/EtherNet/IP/Profinet offload, and six UARTs for RS-232/485 gateways. Its PRU-ICSS subsystem executes protocol stacks in hardware, enabling deterministic cycle times under 100 µs - verified in TI reference designs for industrial PLCs and drive controllers.
