PIC17C7XX_13 Datasheet, PDF (9/306 Pages) Microchip Technology – High-Performance 8-bit CMOS EPROM Microcontrollers with 10-bit A/D

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 PIC17C7XX Prod-
uct Selection System section at the end of this data
sheet. When placing orders, please use the
“PIC17C7XX Product Identification System” at the
back of this data sheet to specify the correct part num-
ber. When discussing the functionality of the device,
memory technology and voltage range does not matter.
There are two memory type options. These are speci-
fied in the middle characters of the part number.
1. C, as in PIC17C756A. These devices have
EPROM type memory.
2. CR, as in PIC17CR756A. These devices have
ROM 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.

2.1 UV Erasable Devices
The UV erasable version, offered in CERQUAD pack-
age, is optimal for prototype development and pilot
programs.
The UV erasable version can be erased and repro-
grammed to any of the configuration modes. Third
party programmers also are available; refer to the Third
Party Guide for a list of sources.
2.2 One-Time-Programmable (OTP)
Devices
The availability of OTP devices is especially useful for
customers expecting frequent code changes and
updates.
The OTP devices, packaged in plastic packages, permit
the user to program them once. In addition to the program
memory, the configuration bits must be programmed.

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.
2.4 Serialized Quick-Turnaround
Production (SQTP^sm) Devices
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.
2.5 Read Only Memory (ROM) Devices
Microchip offers masked ROM versions of several of
the highest volume parts, thus giving customers a low
cost option for high volume, mature products.
ROM devices do not allow serialization information in
the program memory space.
For information on submitting ROM code, please con-
tact your regional sales office.
Note: Presently, NO ROM versions of the
PIC17C7XX devices are available.
