Texas Instruments AM5728BABCXA

Overview

AM5728BABCXA from Texas Instruments is a high-performance Sitara™ Arm applications processor featuring dual Cortex-A15 cores, two C66x DSPs, dual Cortex-M4 coprocessors, four Embedded Vision Engines (EVEs), IVA-HD video subsystem, dual PowerVR SGX544 3D GPU, and hardware crypto accelerators. It supports DDR3-1066 memory, HDMI 1.4a, PCIe Gen2, dual Gigabit Ethernet, and CAN 2.0B - deployed in industrial HMIs and vision-enabled automation systems.

For engineers reviewing the AM5728BABCXA datasheet, AM5728BABCXA pinout, AM5728BABCXA application, or AM5728BABCXA equivalent, key selection criteria include verified EVE support, dual-Cortex-M4 real-time co-processing capability, IVA-HD 4K encode/decode readiness, and 760-pin FCBGA package compatibility with TI's TPS6590379ZWSR PMIC for vdd_dspeve regulation.

Technical Context

The AM5728BABCXA implements a heterogeneous multicore architecture: dual Cortex-A15 CPUs handle OS and control tasks, while two C66x VLIW DSPs execute intensive signal processing; two Cortex-M4 IPU cores manage deterministic real-time functions like PRU-ICSS offload and sensor fusion. The Vision AccelerationPac integrates four EVEs for parallel computer vision workloads without CPU/DSP load.

Its memory subsystem includes two independent DDR3/DDR3L EMIF controllers supporting up to 2GB each, 2.5MB on-chip OCMC RAM with ECC, and GPMC for NAND/NOR/async memory. Video processing is enabled by IVA-HD (4K@15fps H.264), VPE, three display pipelines, HDMI 1.4a encoder, and three VIP modules with dual-input per port.

Key Specifications

Pinout & Package

AM5728BABCXA uses a 23 mm × 23 mm, 0.8-mm pitch, 760-ball FCBGA (ABC) package with 247 GPIOs, 32-bit DDR3/DDR3L interfaces (EMIF1/EMIF2), and dedicated power/ground balls including cap_vbbldo_dspeve, cap_vddram_core1–5, and cap_vddram_mpu1/2. Unused balls (e.g., AF7, AE4, AB26) are NC; reserved balls (Y5, K14) must remain unconnected.

FAQ

What is the maximum DDR3 speed supported by AM5728BABCXA?

AM5728BABCXA supports DDR3-1066 (533 MHz) across both EMIF1 and EMIF2 interfaces, with up to 2 GB addressable memory per channel. This is confirmed in Section 1.1 Features and Table 5-5 of SPRS953G Rev G. The AM5728BABCXA requires matched trace lengths and strict termination per TI's DDR3 board design guidelines in Section 8.2 to achieve stable operation at this speed.

Does AM5728BABCXA include hardware support for CAN FD?

No, AM5728BABCXA implements two DCAN modules compliant only with CAN 2.0B protocol, as explicitly stated in Section 1.1 Features and Table 3-1 of SPRS953G. It does not support CAN FD bit rates, arbitration phase extensions, or flexible data-length frames. For CAN FD, designers must use external transceivers with protocol translation or select newer TI processors like AM65x.

Is the AM5728BABCXA pin-compatible with AM5726BABCXA?

No, AM5728BABCXA is not pin-compatible with AM5726BABCXA despite sharing the same ABC package. Table 3-1 confirms AM5726 lacks EVE, IVA-HD, HDMI, SGX544 GPU, and BB2D - meaning key signal balls (e.g., HDMI_Tx, EVE_CLK, IVA_VID) are NC or repurposed on AM5726. PCB layout and power delivery must be redesigned for AM5726.

What power management IC is recommended for AM5728BABCXA?

Texas Instruments specifies the TPS6590379ZWSR PMIC for AM5728BABCXA, particularly to supply the dedicated vdd_dspeve rail required by the four EVEs. This is mandated in Section 3.1 Device Comparison footnote (6) of SPRS953G. Using any other PMIC risks unstable EVE operation and violates TI's power sequencing requirements in Section 5.9.

How many video input channels does AM5728BABCXA support?

AM5728BABCXA supports up to six concurrent video input channels via three VIP modules (VIP1–VIP3), each with dual-input capability (vin1a/vin1b, vin3a/vin3b, vin5a/vin6a). This is documented in Table 3-1 and Section 1.1 Features ("Three video Input Port (VIP) modules"). All six inputs can be active simultaneously with proper clocking and bandwidth allocation.
