PIC12C67X DEVICE VARIETIES

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 PIC12C67X Product Iden-

tification System section at the end of this data sheet.

When placing orders, please use that page of the data

sheet to specify the correct part number.

For example, the PIC12C67X device “type” is indicated

in the device number:

C, as in PIC12C671. These devices have

EPROM type memory and operate over the

standard voltage range.

LC, as in PIC12LC671. These devices have

EPROM type memory and operate over an

extended voltage range.

CE, as in PIC12CE674. These devices have

EPROM type memory, EEPROM data memory

and operate over the standard voltage range.

LCE, as in PIC12LCE674. These devices have

EPROM type memory, EEPROM data memory

and operate over an extended voltage range.

2.1

UV Erasable Devices

The UV erasable version, offered in windowed pack-

age, is optimal for prototype development and pilot pro-

grams.

The UV erasable version can be erased and repro-

grammed

any

the

configuration

modes.

Microchip's PICSTART® Plus and PRO MATE® pro-

grammers both support the PIC12C67X. Third party

programmers also are available; refer to the Microchip

Third Party Guide for a list of sources.

2.2

One-Time-Programmable (OTP)

Devices

The availability of OTP devices is especially useful for

customers who need the flexibility for frequent code

updates and small volume applications.

The OTP devices, packaged in plastic packages, per-

mit the user to program them once. In addition to the

program memory, the configuration bits must also be

programmed.

Note:

Please note that erasing the device will

also erase the pre-programmed internal

calibration value for the internal oscillator.

The calibration value must be saved prior

to erasing the part.

2.3

Quick-Turn-Programming (QTP)

Devices

Microchip offers a QTP Programming Service for fac-

tory production orders. This service is made available

for users who choose not to program a medium to high

quantity of units and whose code patterns have stabi-

lized. 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 produc-

tion shipments are available. Please contact your local

Microchip Technology sales office for more details.

2.4

Serialized Quick-Turn Programming

(SQTPSM) Devices

Microchip offers a unique programming service where

a few user-defined locations in each device are pro-

grammed with different serial numbers. The serial num-

bers 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.
