Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the TSSOP-14 configuration. Cross-reference the device revision ID during production to maintain consistency with silicon errata and application notes.

Microcontrollers Selection Notes

Select this model when 32 KB of program memory is sufficient for the application logic. The TSSOP-14 package is suitable for space-constrained designs requiring through-hole or surface-mount assembly. Consider the 12-bit ADCC resolution if higher precision analog input processing is required compared to standard 10-bit ADCs.
