DEVICE VARIETIES

A variety of frequency ranges and packaging options

are available. The PIC14000 Product Selection System

section at the end of this data sheet provides the

devices options to be selected for your speciﬁc applica-

tion and production requirements. When placing

orders, please use the “PIC14000 Product Identiﬁca-

tion System” at the back of this data sheet to specify the

correct part number.

2.1

UV Erasable Devices

The UV erasable version, offered in CERDIP package,

is optimal for prototype development and pilot

programs.

The UV erasable version can be erased and

reprogrammed to any of the conﬁguration modes.

Microchip's

PICSTART®

, PICSTART-PLUS

and

PRO MATE™ programmers all support programming of

the PIC14000. Third party programmers also are avail-

able; 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 or small volume applications.

The OTP devices, packaged in plastic packages permit

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 calibration

factors. Please refer to AN621 for more

information.

2.3

Quick-Turnaround-Production (QTP)

Devices

Microchip offers a QTP Programming Service for

factory 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 stabilized. The devices are identical to

the OTP devices but with all EPROM locations and

fuse options already programmed by the factory.

Certain code and prototype veriﬁcation procedures do

apply before production shipments are available.

Please contact your local Microchip Technology sales

ofﬁce for more details.

2.4

Serialized Quick-Turnaround

Production (SQTPSM) 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

random,

pseudo-random

sequential.

Serial programming allows each device to have a

unique number which can serve as an entry-code,

password or ID number.
