The PIC16F627A/628A/648A are 18-pin Flash-based
members of the versatile PIC16F627A/628A/648A
family of low-cost, high-performance, CMOS, fully-
static, 8-bit microcontrollers.

architecture.
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.

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.

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
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.
