Microcontrollers Procurement Notes

Verify the specific suffix '/SP' against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding the 28-pin DIP configuration. Confirm that the EPROM technology meets long-term availability requirements for the intended production volume.

Microcontrollers Selection Notes

Select this component when a 20 MHz operating speed is required alongside high-resolution analog capabilities. The EPROM memory allows for field reprogramming during development. Consider the wide operating voltage range of 2.7V to 6.0V for systems requiring flexible power supply options without additional regulation circuitry.

Microcontrollers Part Context

This part belongs to the PIC14000 family of 28-pin programmable mixed-signal controllers. It utilizes CMOS EPROM technology for non-volatile storage. The architecture is based on a Harvard structure with separate 14-bit instruction and 8-bit data buses, enabling efficient code execution and compact programming.

Microcontrollers Replacement Considerations

Check for direct pin-compatible alternatives within the PIC14000 series with different frequency ratings or packaging options. Verify if newer generations from Microchip offer upward compatibility while maintaining the same peripheral set and memory size.
