UV Erasable Devices
2.0
DEVICE VARIETIES
Each device has a variety of frequency ranges and
packaging options. Depending on application and pro-
duction requirements, the proper device option can be
selected using the information in the PIC17C75X Prod-
uct Selection System section at the end of this data
sheet. When placing orders, please use the
“PIC17C75X Product Identification System” at the back
of this data sheet to specify the correct part number.
When discussing the functionality of the device, mem-
ory technology and voltage range does not matter.
The UV erasable version, offered in CERQUAD pack-
age, is optimal for prototype development and pilot pro-
grams.
The UV erasable version can be erased and repro-
grammed to any of the configuration modes.

party programmers also are available; refer to the Third
Party Guide for a list of sources.
2.2
One-Time-Programmable (OTP)
Devices
There are three memory type options. These are spec-
ified in the middle characters of the part number.
The availability of OTP devices is especially useful for
customers expecting frequent code changes and
updates.
1. C, as in PIC17C756. These devices have
EPROM type memory.
2. CR, as in PIC17CR756. These devices have
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.
ROM type memory.
3. F, as in PIC17F756. These devices have Flash
type memory.
All these devices operate over the standard voltage
range. Devices are also offered which operate over an
extended voltage range (and reduced frequency
range). Table 2-1 shows all possible memory types and
voltage range designators for a particular device.
These designators are in bold typeface.
2.3
Quick-Turnaround-Production (QTP)
Devices
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 options
already programmed by the factory. Certain code and
prototype verification procedures apply before produc-
tion shipments are available. Please contact your local
Microchip Technology sales office for more details.

Serialized Quick-Turnaround
Production (SQTPSM) Devices
Note: Not all memory technologies are available
for a particular device.
Microchip offers a unique programming service where
a few user-defined locations in each device are pro-
grammed with different serial numbers.The serial num-
bers 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.
