Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific GQR suffix indicates the tape-and-reel packaging format compatible with automated assembly processes. Ensure design compliance with the specified 2.7 V to 3.6 V supply voltage range and -40°C to +85°C operating temperature limits. Review the datasheet revision history for any updates to electrical characteristics or pin configurations prior to finalizing procurement orders.

Selection Notes

Select this model when the application requires integrated CAN functionality alongside high-resolution analog conversion capabilities within an 8-bit architecture. The 64-pin TQFP package suits designs with moderate I/O density requirements. Consider the internal oscillator accuracy if external crystal components are undesirable. Evaluate the 24 available GPIO pins against system interface needs to ensure sufficient connectivity without additional multiplexing hardware.
