PIC16C8X 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

“PIC16C8X

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.

C, as in PIC16C84. These devices have

EEPROM program memory and operate over

the standard voltage range.

LC, as in PIC16LC84. These devices have

EEPROM 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 C (CR) also implies the LC (LCR)

versions.

2.1

Electrically Erasable 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 version

is that they can be erased and reprogrammed in-circuit,

or by device programmers, such as Microchip's

PICSTART

™ or PRO MATE™ 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

EEPROM locations and conﬁguration options already

programmed

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.
