Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required voltage domains (1.8V core, 3.3V I/O) during design validation. Confirm RoHS compliance status through current datasheets before finalizing procurement specifications.

Microcontrollers Selection Notes

Select this component for applications requiring integrated Ethernet and USB connectivity within a single chip. Consider the 512KB Flash capacity for complex firmware requirements. Evaluate the need for external memory interfaces if larger storage is needed, as this derivative lacks an external bus interface compared to A0 series parts.

Microcontrollers Part Context

This part belongs to the AT32UC3A family of high-performance, low-power 32-bit microcontrollers. It utilizes the AVR32 architecture optimized for cost-sensitive embedded applications. The family emphasizes code density, performance, and power efficiency, supporting modern operating systems through its MPU and interrupt controller features.

Microcontrollers Replacement Considerations

AT32UC3A1256 offers similar functionality with reduced Flash and SRAM capacity.
