Microcontrollers Procurement Notes

Verify the specific suffix 'RDTIM' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the required package variant. Confirm RoHS compliance status via the manufacturer's current datasheet revision. Validate that the ordering code matches the exact pinout and electrical specifications required for the design.

Microcontrollers Selection Notes

Select this component when a dedicated 8-bit MCU with integrated CAN functionality is required. It is suitable for designs needing substantial non-volatile memory for bootloaders and data storage. Consider the package availability for VQFP44, PLCC44, VQFP64, or PLCC52 depending on board space constraints. Evaluate the need for SPI interface, which is limited to specific packages like PLCC52 and VPFP64.
