PIC16C64X & PIC16C66X devices are 28-pin and 40-pin EPROM-based members of the versatile PIC16CXXX family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers. All PIC16/17 microcontrollers employ an advanced RISC architecture. The PIC16CXXX family has enhanced core features, 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.
