The PIC16C62X devices are 18 and 20-Pin ROM/
EPROM-based members of the versatile PICmicro
family of low cost, high performance, CMOS, fully-
static, 8-bit microcontrollers.
All PICmicro microcontrollers employ an advanced
RISC architecture. The PIC16C62X devices 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 single
cycle, except for program branches (which require two
cycles). A total of 35 instructions (reduced instruction
set) are available. Additionally, a large register set
gives some of the architectural innovations used to
achieve a very high performance.
PIC16C62X microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
The PIC16C620A, PIC16C621A and PIC16CR620A
have 96 bytes of RAM. The PIC16C622(A) has 128
bytes of RAM. Each device has 13 I/O pins and an 8-
bit timer/counter with an 8-bit programmable prescaler.
In addition, the PIC16C62X adds two analog compara-
tors with a programmable on-chip voltage reference
module. The comparator module is ideally suited for
applications requiring a low cost analog interface (e.g.,
battery chargers, threshold detectors, white goods
controllers, etc).
PIC16C62X devices have special features to reduce
external components, thus reducing system cost,
enhancing system reliability and reducing power con-
sumption. There are four oscillator options, of which the
single pin RC oscillator provides a low cost solution, the
LP oscillator minimizes power consumption, XT is a
standard crystal, and the HS is for High Speed crystals.
The SLEEP (Power-down) mode offers power savings.
The user can wake-up the chip from SLEEP through
several external and internal interrupts and RESET.
A highly reliable Watchdog Timer with its own on-chip
RC oscillator provides protection against software
lock- up.
A UV-erasable CERDIP-packaged version is ideal for
code development while the cost effective One-Time-
Programmable (OTP) version is suitable for production
in any volume.
Table 1-1 shows the features of the PIC16C62X mid-
range microcontroller families.
A simplified block diagram of the PIC16C62X is shown
in Figure 3-1.
The PIC16C62X series fits perfectly in applications
ranging from battery chargers to low power remote
sensors.

GENERAL DESCRIPTION
The
EPROM
technology
makes
®
customization of application programs (detection
levels, pulse generation, timers, etc.) extremely fast
and convenient. The small footprint packages make
this microcontroller series perfect for all applications
with space limitations. Low cost, low power, high
performance, ease of use and I/O flexibility make the
PIC16C62X very versatile.
1.1
Those users familiar with the PIC16C5X family of
microcontrollers will realize that this is an enhanced
version of the PIC16C5X architecture. Please refer to
Appendix A for a detailed list of enhancements. Code
written for the PIC16C5X can be easily ported to
PIC16C62X family of devices (Appendix B). The
PIC16C62X family fills the niche for users wanting to
migrate up from the PIC16C5X family and not needing
various peripheral features of other members of the
PIC16XX mid-range microcontroller family.
1.2
The PIC16C62X family is supported by a full-featured
macro assembler, a software simulator, an in-circuit
emulator, a low cost development programmer and a
full-featured programmer. Third Party “C” compilers are
also available.
