2.0 PIC12C5XX DEVICE VARIETIES

A variety of packaging options are available.

Depending on application and production

requirements, the proper device option can be

selected using the information in this section. When

placing orders, please use the PIC12C5XX Product

Identification 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 ceramic side

brazed package, is optimal for prototype development

and pilot programs.

The UV erasable version can be erased and

reprogrammed to any of the configuration modes.

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.

Microchip’s PICSTART® PLUS and PRO MATE® pro-

grammers all support programming of the PIC12C5XX.

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 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.

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 con-

tact 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 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.

2.5 Read Only Memory (ROM) Device

Microchip offers masked ROM to give the customer a

low cost option for high volume, mature products.
