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

âPIC17C75X Product Identiï¬cation Systemâ 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.

There are three memory type options. These are spec-

iï¬ed in the middle characters of the part number.

1. C, as in PIC17C756. These devices have

EPROM type memory.

2. CR, as in PIC17CR756. These devices have

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.

2.1 UV Erasable Devices

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 conï¬guration modes.

Microchip's programming of the PIC17C75X. 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, per-

mit the user to program them once. In addition to the

program memory, the conï¬guration bits must be pro-

grammed.

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 conï¬guration options

already programmed by the factory. Certain code and

prototype veriï¬cation procedures apply before produc-

tion shipments are available. Please contact your local

Microchip Technology sales ofï¬ce for more details.

2.4 Serialized Quick-Turnaround

Production (SQTPSM) Devices

Microchip offers a unique programming service where

a few user-deï¬ned 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.
