PIC16F628A 8 Bit PIC Microcontroller IC from Microchip TechnologyThe PIC16F628 are 18 Pin FLASH based members of the versatile PIC16CXX family of low cost, high performance, CMOS, fully static, 8 bit microcontrollers. All PIC microcontrollers employ an advanced RISC architecture. The PIC16F628 have 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
