Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing design constraints regarding voltage levels and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component when a balance of moderate memory capacity and specialized connectivity like USB and LCD driving is required. Consider the B3 series architecture for applications needing robust peripheral integration without the higher pin counts of larger devices.
Part Context
This part belongs to the AVR XMEGA B3 family, designed for high-performance and low-power embedded applications. The family emphasizes code efficiency and fast wake-up times, making it suitable for battery-operated devices requiring significant processing power relative to its size.
Replacement Considerations
Consult official Microchip documentation for verified substitute part numbers within the same product family or cross-reference with equivalent components from other manufacturers based on specific electrical and pinout requirements.
