The PIC16CE62X are 18 and 20-Pin EPROM-based
members of the versatile PICmicro
high-performance,
microcontrollers with EEPROM data memory.
All PICmicro
RISC architecture. The PIC16CE62X family has
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
separate 8-bit wide data. The two-stage instruction
pipeline allows all instructions to execute in a sin-
gle-cycle, except for program branches (which require
two cycles). A total of 35 instructions (reduced instruc-
tion set) are available. Additionally, a large register set
gives some of the architectural innovations used to
achieve a very high performance.
PIC16CE62X microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
The PIC16CE623 and PIC16CE624 have 96 bytes of
RAM. The PIC16CE625 has 128 bytes of RAM. Each
microcontroller contains a 128x8 EEPROM memory
array for storing non-volatile information, such as cali-
bration data or security codes. This memory has an
endurance of 1,000,000 erase/write cycles and a reten-
tion of 40 plus years.
Each device has 13 I/O pins and an 8-bit timer/counter
with an 8-bit programmable prescaler. In addition, the
PIC16CE62X adds two analog comparators 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,
controllers, etc).
PIC16CE62X 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 PIC16CE62X
mid-range microcontroller families.
A simplified block diagram of the PIC16CE62X is
shown in Figure 3-1.
The PIC16CE62X series fits perfectly in applications
ranging
low-power remote sensors. The EPROM technology
makes customization of application programs (detec-
tion levels, pulse generation, timers, etc.) extremely
fast and convenient. The small footprint packages
make this microcontroller series perfect for all applica-
tions with space limitations. Low-cost, low-power,
high-performance, ease of use and I/O flexibility make
the PIC16CE62X very versatile.

The PIC16CE62X 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. A “C” compiler is also
available.
