Microchip PIC16F648A Microcontroller DIP 18 pin
Description
The PIC16F648A is an 18-pin Flash-based member of the versatile PIC16F627A/628A/648A family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers.
All PIC® microcontrollers employ an advanced RISC architecture. The PIC16F648A has 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.
