18-pin Flash-Based, 8-Bit CMOS Microcontrollers With NanoWatt Technology

The PIC16F627A PIC16F628A PIC16F648A are 18-pin Flash-based members of the versatile PIC16F627A PIC16F628A PIC16F648A family of low-cost, high-performance, CMOS, fully- static, 8-bit Microcontrollers ? All PIC Microcontrollers employ an advanced RISC architecture. The PIC16F627A PIC16F628A PIC16F648A 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. PIC16F627A PIC16F628A PIC16F648A Microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit Microcontrollers in their class. PIC16F627A PIC16F628A PIC16F648A devices have integrated features to reduce external components, thus reducing system cost, enhancing system reliability and reducing power consumption. The PIC16F627A PIC16F628A PIC16F648A has 8 Oscillator configurations. The single-pin RC Oscillator provides a low-cost solution. The LP Oscillator minimizes power consumption, XT is a standard crystal, and INTOSC is a self-contained precision two-speed internal Oscillator By Microchip Technology Inc.
