XAM5728BABCXE

Overview

The AM5728BABCXEA is a Sitara microprocessor from Texas Instruments featuring a seven-core heterogeneous architecture. It integrates dual ARM Cortex-A15 cores, four C66x fixed-point DSPs, an ARM Cortex-M4 core, and a SGX544 3D graphics accelerator. The device operates within a -40°C to +105°C temperature range and utilizes a 760-pin FCBGA package. Key electrical specifications include a maximum clock frequency of 1.5 GHz for the Cortex-A15 cores, 750 MHz for the DSPs, and 532 MHz for the Cortex-M4. It supports DDR3 and DDR3L memory interfaces and includes floating-point arithmetic capabilities.

Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct silicon revision and packaging configuration. Confirm that the specific suffix matches the required commercial or industrial temperature grade and pinout compatibility. Cross-reference with the latest datasheet errata to identify any known silicon revisions or functional updates relevant to the production batch.

Selection Notes

Select this component when a balance of high-performance computing and real-time deterministic processing is required. The inclusion of dedicated DSP cores makes it suitable for complex signal processing tasks alongside general-purpose application execution. Ensure the design accommodates the necessary power delivery requirements for the multiple voltage domains and the thermal dissipation needs of the 760-pin package.

Part Context

This processor belongs to the AM572x Sitara family, designed for applications requiring robust multimedia processing and connectivity. It shares architectural similarities with other members of the AM57xx series but offers a specific configuration of cores and peripherals tailored for demanding embedded environments. The device represents a transition point in the Sitara portfolio towards higher integration of heterogeneous computing resources.

Replacement Considerations

Direct substitutes within the same package and pinout may include other variants from the AM572x family, such as the AM5729 or AM5726, provided their specific feature sets align with the application requirements. Verify peripheral availability and core counts before substitution.
