2.3
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.
Quick-Turnaround-Production (QTP)
Devices
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.
Note:
Please note that erasing the device will
also erase the pre-programmed calibration
factors. Please refer to AN621 for more
information.
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.

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.
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.
2.2
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.
