PIC16F8X DEVICE VARIETIES
2.3
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 “PIC16F8X Product
Identification System” at the back of this data sheet to
specify the correct part number.
There are four device “types” as indicated in the device
number.
1.
F,
as in PIC16F84. These devices have Flash
program memory and operate over the standard
voltage range.
LF,
as in PIC16LF84. These devices have Flash
program memory and operate over an extended
voltage range.
CR,
as in PIC16CR83. These devices have
ROM program memory and operate over the
standard voltage range.
LCR,
as in PIC16LCR84. These devices have
ROM program memory and operate over an
extended voltage range.
Serialized Quick-Turnaround-
Production (SQTP
SM
) Devices
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 sequential.
Serial programming allows each device to have a
unique number which can serve as an entry-code,
password or ID number.
For information on submitting a SQTP code, please
contact your Microchip Regional Sales Office.

2.4
ROM Devices
3.
Some of Microchip’s devices have a corresponding
device where the program memory is a ROM. These
devices give a cost savings over Microchip’s traditional
user programmed devices (EPROM, EEPROM).
ROM devices (PIC16CR8X) do not allow serialization
information in the program memory space. The user
may program this information into the Data EEPROM.
For information on submitting a ROM code, please
contact your Microchip Regional Sales Office.
4.
When discussing memory maps and other architectural
features, the use of
F
and
CR
also implies the
LF
and
LCR
versions.
2.1
Flash Devices
These devices are offered in the lower cost plastic
package, even though the device can be erased and
reprogrammed. This allows the same device to be used
for prototype development and pilot programs as well
as production.
A further advantage of the electrically-erasable Flash
version is that it can be erased and reprogrammed in-
circuit, or by device programmers, such as Microchip's
PICSTART
®
Plus or PRO MATE
®
II programmers.
2.2
Quick-Turnaround-Production (QTP)
Devices
Microchip offers a QTP Programming Service for
factory 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 stabilized. The devices have all Flash
locations and configuration options already pro-
grammed by the factory. Certain code and prototype
verification procedures do apply before production
shipments are available.
For information on submitting a QTP code, please
contact your Microchip Regional Sales Office.
