The PIC16F627A/PIC16F628A/648A are 18-Pin FLASHbased members of the versatile PIC16CXX family of low cost, high performance, CMOS, fully-static, 8-bit
microcontrollers. external clock source.
All PICmicro® microcontrollers employ an advanced RISC architecture. The PIC16F627A/PIC16F628A/648A have 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 singlecycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available, complemented by a large register set.
A highly reliable Watchdog Timer with its own on-chip RC oscillator provides protection against software lockup. Table 1-1 shows the features of the PIC16F627A/ 628A/648A mid-range microcontroller families. A simplified block diagram of the PIC16F627A/PIC16F628A/ 648A is shown in Figure 3-1. The PIC16F627A/628A/648A series fits in applications ranging from battery chargers to low power remote
