• Integrates two independent Programmable Real-Time Unit (PRU) cores for deterministic real-time control tasks.
• Includes a dedicated SATA controller supporting SATA I and II standards for high-speed mass storage connectivity.
• Features a comprehensive multimedia interface set including Ethernet MAC, USB OTG, and video port interfaces.

Applications

• Set Top Box
• Industrial Automation
• Medical, Healthcare, Fitness

Procurement Notes

Verify the specific suffix 'A3' against official documentation to confirm silicon revision level and manufacturing lot details. Ensure compatibility with required operating temperature ranges and power supply configurations before integration into final designs.

Selection Notes

Select this component when deterministic real-time processing via PRUs is required alongside standard ARM application execution. Consider the 375 MHz performance tier if lower power consumption is prioritized over the higher 456 MHz variant.

Part Context

This part belongs to the Texas Instruments Sitara AM1808 series of low-power applications processors. The series targets OEMs and ODMs requiring robust OS support and rich user interfaces within a fully integrated mixed processor solution.
