2.0 PIC16C7X DEVICE VARIETIES
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 the PIC16C7X Product Identifi-
cation System section at the end of this data sheet.
When placing orders, please use that page of the data
sheet to specify the correct part number.
For the PIC16C7X family, there are two device “types”
as indicated in the device number:
1. C, as in PIC16C74. These devices have
EPROM type memory and operate over the
standard voltage range.
2. LC, as in PIC16LC74. These devices have
EPROM type memory and operate over an
extended voltage range.
2.1 UV Erasable Devices
The UV erasable version, offered in CERDIP package
is optimal for prototype development and pilot
programs. This version can be erased and
reprogrammed to any of the oscillator modes.
Microchip's PICSTART® Plus and PRO MATE® II
programmers both support programming of the
PIC16C7X.
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 and 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 also 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 (SQTPSM) 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.
