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

tem at the back of this data sheet to specify the correct
part number.
2.1
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.

are available; refer to the Microchip Third Party Guide
(DS00104) 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.

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
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.
