2.0
A variety of frequency ranges and 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 PIC16C5X Product Identifica-
tion System at the back of this data sheet to specify the
correct part number.
For the PIC16C5X family of devices, there are four
device types, as indicated in the device number:

2.1
The UV erasable versions offered in CERDIP pack-
ages, are optimal for prototype development and pilot
programs.
UV erasable devices can be programmed for any of the
four oscillator configurations. Microchip’s
PICSTART
both support programming of the PIC16C5X. Third
party programmers also are available. Refer to the
Third Party Guide (DS00104) for a list of sources.
2.2
The availability of OTP devices is especially useful for
customers expecting frequent code changes and
updates, or small volume applications.
The OTP devices, packaged in plastic packages, per-
mit the user to program them once. In addition to the
program memory, the configuration bits must be pro-
grammed.

C, as in PIC16C54C. These devices have
EPROM program memory and operate over the
standard voltage range.
LC, as in PIC16LC54A. These devices have
EPROM program memory and operate over an
extended voltage range.
CR, as in PIC16CR54A. These devices have
ROM program memory and operate over the
standard voltage range.

2.3
Microchip offers a QTP Programming Service for fac-
tory 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 stabi-
lized. The devices are identical to the OTP devices but
with all EPROM locations and configuration bit options
already programmed by the factory. Certain code and
prototype verification procedures apply before produc-
tion shipments are available. Please contact your
Microchip Technology sales office for more details.
2.4
Microchip offers the 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 sequen-
tial. The devices are identical to the OTP devices but
with all EPROM locations and configuration bit options
already programmed by the factory.
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 versions of several of
the highest volume parts, giving the customer a low
cost option for high volume, mature products.
