PIC16CE62X

1.0

GENERAL DESCRIPTION

The PIC16CE62X are 18 and 20-Pin EPROM-based

members of the versatile PIC

family of low-cost,

high-performance,

CMOS,

fully-static,

8-bit

microcontrollers with EEPROM data memory.

All PIC

microcontrollers employ an advanced RISC

architecture. The PIC16CE62X family has enhanced

core features, eight-level deep stack, and multiple inter-

nal 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 single-cycle, except for pro-

gram 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.

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,

threshold

detectors,

white

goods

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 from multi-pocket battery chargers to

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.

1.1

Development Support

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.

Quick-Turn-Programming (QTP)

Devices

A variety of frequency ranges and packaging options are

available. Depending on application and production

requirements the proper device option can be selected

using the information in the PIC16CE62X Product

Identification System section at the end of this data

sheet. When placing orders, please use this page of the

data sheet to specify the correct part number.

2.1

UV Erasable Devices

The UV erasable version, offered in the CERDIP pack-

age is optimal for prototype development and pilot

programs. This version can be erased and

reprogrammed to any of the oscillator modes.

programmers both support programming of the

PIC16CE62X.

Microchip offers a QTP Programming Service for

factory production orders. This service is made

available for users who chose not to program a medium

to high quantity of units and whose code patterns have

stabilized. The devices are identical to the OTP devices

but with all EPROM locations and configuration options

already programmed by the factory. Certain code and

prototype verification procedures apply before

production shipments are available. Please contact

your Microchip Technology sales office for more details.

2.4

Serialized Quick-Turn-Programming

(SQTP

) Devices

2.2

One-Time-Programmable (OTP)

Devices

Microchip offers a unique programming service where

a few user-defined locations in each device are

programmed with different serial numbers. The serial

numbers may be random, pseudo-random or

sequential.

Serial programming allows each device to have a

unique number which can serve as an entry-code,

password or ID number.

The availability of OTP devices is especially useful for

customers who need the flexibility for frequent code

updates and small volume applications. In addition to

the program memory, the configuration bits must also

be programmed.
