All PICmicro® microcontrollers employ an advanced RISC architecture. The PIC16F627A/628A/648A 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/628A/648A microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers in their class. PIC16F627A/628A/648A devices have integrated features to reduce external components, thus reducing system cost, enhancing system reliability and reducing power consumption. The PIC16F627A/628A/648A 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. The HS mode is for High-Speed crystals. The EC mode is for an external clock source. The Sleep (Power-down) mode offers power savings. Users can wake-up the chip from Sleep through several external interrupts, internal interrupts and Resets. A highly reliable Watchdog Timer with its own on-chip RC oscillator provides protection against software lock- up. Table 1-1 shows the features of the PIC16F627A/628A/ 648A mid-range microcontroller family. A simplified block diagram of the PIC16F627A/628A/ 648A is shown in Figure 3-1. The PIC16F627A/628A/648A series fits in applications ranging from battery chargers to low power remote sensors. The Flash technology makes customizing application programs (detection levels, pulse genera- tion, timers, etc.) extremely fast and convenient. The small footprint packages makes this microcontroller series ideal for all applications with space limitations. Low cost, low power, high performance, ease of use and I/O flexibility make the PIC16F627A/628A/648A very versatile. 1.1 Development Support The PIC16F627A/628A/648A family is supported by a full-featured macro assembler, a software simulator, an in-circuit emulator, a low cost in-circuit debugger, a low cost development programmer and a full-featured programmer. A Third Party “C” compiler support tool is also available.
