Microcontrollers Procurement Notes

Verify the specific suffix 'SP' corresponds to the SPDIP package type as defined in the Microchip Product Identification System. Confirm that the '04E' designation aligns with the required operating temperature and frequency specifications for your application environment before finalizing procurement.

Microcontrollers Selection Notes

Select this component when UV-erasable EPROM memory is required for code development or prototyping. It is suitable for designs needing five analog input channels and robust serial communication capabilities. Ensure the 28-pin SPDIP form factor fits the mechanical constraints of the target PCB layout.

Microcontrollers Part Context

This device belongs to the PIC16C63A/65B/73B/74B series, which represents an enhanced version of the earlier PIC16C5X architecture. It shares core architectural features with the PIC16C74B but offers fewer I/O pins and A/D channels. The series is designed for cost-effective, high-performance embedded control applications.
