Depending
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
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.
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
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.

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 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
Microchip offers a unique programming service where
a few user-defined locations in each device are
programmed with different serial numbers. The serial
numbers
sequential.
Serial programming allows each device to have a
unique number which can serve as an entry-code,
password or ID number.
2.5
Microchip offers masked ROM to give the customer a
low cost option for high volume, mature products.
