PIC16F628A-I/P

Product Summary

The PIC16F628A-I/P is a flash-based 8-bit CMOS microcontroller with nanowatt technology. It has enhanced core features, an eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The PIC16F628A-I/P has integrated features to reduce external components, thus reducing system cost, enhancing system reliability and reducing power consumption. The PIC16F628A-I/P has 8 oscillator configurations. The single-pin RC oscillator provides a low-cost solution.
