PIC16F628A Microcontroller

The PIC16F628A is 18-pin Flash-based members of the versatile PIC16F628A family of low-cost, high-performance, CMOS, fullystatic, 8-bit microcontrollers. All PIC® microcontrollers employ an advanced RISC architecture. The PIC16F628A 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 separate 8-bit wide data. The two-stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available, complemented by a large register set.

PIC16F628A microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers in their class. PIC16F628A devices have integrated features to reduce external components, thus reducing system cost, enhancing system reliability and reducing power consumption.
