Microcontrollers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range and '/P' denotes the PDIP package. Confirm the 'A' revision matches design requirements. Check datasheet DS30453E for electrical characteristics and pinout details before finalizing procurement specifications.

Microcontrollers Selection Notes

Select this component for applications requiring low-cost EPROM-based development or small-volume production. Ensure the 20 MHz speed rating meets timing constraints. Verify that the 12 available I/O lines are sufficient for the interface requirements. Consider the 18-pin DIP package for through-hole mounting needs.

Microcontrollers Part Context

This part belongs to the PIC16C5X series of 8-bit CMOS microcontrollers. It shares architectural similarities with the PIC16C54 and PIC16C57 but offers intermediate memory capacity. The device utilizes UV-erasable EPROM technology, distinguishing it from OTP or ROM variants within the same family.

Microcontrollers FAQ

What oscillator modes are supported by the PIC16C56A?

The device supports Low Power (LP), Crystal/Resonator (XT), High Speed (HS), and Resistor/Capacitor (RC) oscillator configurations.

How does the instruction pipeline operate?

Instructions execute in a single cycle except for program branches, which take two cycles due to pipeline flushing during fetch operations.
