PIC16F8X 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 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.

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.

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.

2.3

Serialized Quick-Turnaround-

Production (SQTP

) 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

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

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.
