The 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 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. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance.
