    Microcontroller IC 8-Bit 20MHz 3.5KB (2K x 14) FLASH 18-SOIC PIC16F628A-I/SO

    Microcontroller IC 8-Bit 20MHz 3.5KB (2K x 14) FLASH 18-SOIC PIC16F628A-I/SO


    The PIC16F627A/628A/648A are 18-pin Flash-based

    members of the versatile PIC16F627A/628A/648A

    family of low-cost, high-performance, CMOS, fullystatic,

    8-bit microcontrollers.

    All PIC® 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 singlecycle,

    except for program branches (which require two

    cycles). A total of 35 instructions (reduced instruction

    set) are available, complemented by a large register


    PIC16F627A/628A/648A microcontrollers typically

    achieve a 2:1 code compression and a 4:1 speed

    improvement over other 8-bit microcontrollers in their


    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 lockup.

    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 generation,

    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.
