2.0 rfPIC12C509AG/509AF DEVICE

VARIETIES

A variety of packaging options are available. Depend-

ing on application and production requirements, the

proper device option can be selected using the infor-

mation in this section. When placing orders, please use

the rfPIC12C509AG/509AF Product Identification Sys-

tem at the back of this data sheet to specify the correct

part number.

2.1 UV Erasable Devices

The UV erasable version, offered in a windowed

ceramic DIP package, is optimal for prototype devel-

opment 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 PICSTARTÂ® PLUS and PRO MATEÂ® pro-

grammers all support programming of the

rfPIC12C509AG/509AF. Third party programmers also

are available; refer to the Microchip Third Party Guide

(DS00104) 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 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 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.
