• Supports multimedia applications via dedicated audio serial ports and high-speed DMA capabilities.
• Provides robust connectivity through integrated USB host and OTG controllers alongside Ethernet MAC.
• Includes extensive peripheral set with multiple timers, capture modules, and encoder pulse inputs.

Applications

• Industrial Automation
• Test and Measurement
• Home Automation
• Portable Data Terminals

Procurement Notes

Verify the specific suffix 'ZKB' confirms the 256-ball PBGA package configuration. Ensure the required operating temperature range aligns with commercial, industrial, or automotive specifications as defined in the datasheet. Confirm silicon revision compatibility if integrating with existing firmware or hardware designs referencing earlier production data versions.

Selection Notes

Select this component when a mixed-processor solution requiring both high-performance computing and real-time deterministic control is necessary. The inclusion of PRUSS allows offloading time-critical tasks from the main ARM core. Consider the available memory map and peripheral multiplexing to ensure sufficient resources for the target application's interface requirements.

Part Context

This part belongs to the Sitara family of ARM microprocessors designed for OEMs and ODMs. It combines a general-purpose ARM9 processor with specialized subsystems to support rich user interfaces and robust operating systems. The architecture emphasizes low power consumption while maintaining high processing performance through pipelining and efficient memory management units.

Replacement Considerations

Consult the official Texas Instruments product migration guide for verified substitute part numbers within the Sitara family. Cross-referencing pinouts and memory maps is essential when considering alternative models.
