Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding pinout and voltage levels. Cross-reference datasheet revision history for any updates to electrical characteristics or mechanical dimensions prior to final procurement decisions.

Microcontrollers Selection Notes

Select this component when project requirements include integrated CAN bus connectivity alongside standard AVR peripheral interfaces. Consider the 32K Flash capacity for application code size and the availability of JTAG debugging capabilities. Evaluate power consumption profiles across different sleep modes if battery operation is a constraint within the target system design.

Microcontrollers Part Context

This part belongs to the AT90CAN series, which shares hardware and software compatibility with the AT90CAN64 and AT90CAN128 models. The primary distinction among these variants lies in their non-volatile memory sizes. This specific model provides the baseline memory configuration within the family while maintaining identical peripheral sets and instruction set architectures.
