PIC16F628A 8 Bit PIC Microcontroller IC from Microchip Technology

The PIC16F628 are 18-Pin FLASH-based members ofthe versatile PIC16CXX family of low-cost,high-performance, CMOS, fully-static, 8-bitmicrocontrollers.All PIC microcontrollers employ an advanced RISC  architecture.The  PIC16F628 have enhancedcore 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 pipelineallows all instructions to execute in a single cycle,except for program branches (which require twocycles). A  total of 35  instructions  (reduced instructionset) are available. Additionally, a large register set givessome of the architectural innovations used to achieve avery high performance.
