Microcontrollers Procurement Notes

Verify the specific suffix 'E' against official Microchip documentation to confirm environmental or reliability specifications. Ensure the SOIC-18 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component when a cost-effective 8-bit solution with moderate I/O count is required. The 4 MHz speed suits applications not demanding high-frequency processing. Consider the OTPROM limitation for production volumes where reprogramming is unnecessary. Verify that the 13 available I/O pins meet the interface requirements of the target system design.

Microcontrollers Part Context

This part belongs to the PIC16C55X series of EPROM/OTP-based 8-bit microcontrollers. It shares architectural similarities with other members like the PIC16C554 and PIC16C557 but differs in memory size and pin configuration. The series is designed for simple, low-cost control applications using standard CMOS technology.

Microcontrollers Replacement Considerations

Direct substitutes within the same family include PIC16C558-04I/SO and PIC16C558-04JW. Cross-family replacements require careful evaluation of pin compatibility and memory resources.
