PIC16C6X 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 PIC16C6X 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 PIC16C6X family of devices, there are four

device “types” as indicated in the device number:

C, as in PIC16C64. These devices have

EPROM type memory and operate over the

standard voltage range.

LC, as in PIC16LC64. These devices have

EPROM type memory and operate over an

extended voltage range.

CR, as in PIC16CR64. These devices have

ROM program memory and operate over the

standard voltage range.

LCR, as in PIC16LCR64. These devices have

ROM program memory and operate over an

extended voltage range.

2.1

UV Erasable Devices

The UV erasable version, offered in CERDIP package

optimal

for

prototype

development

and

pilot

programs.

This

version

can

erased

and

reprogrammed to any of the oscillator modes.

Microchip's PICSTART® Plus and PRO MATE® II

programmers

both

support

programming

the

PIC16C6X.

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 (SQTP

SM) 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.

ROM devices do not allow serialization information in

the program memory space. The user may have this

information programmed in the data memory space.

For information on submitting ROM code, please con-

tact your regional sales ofﬁce.

2.5

Read Only Memory (ROM) Devices

Microchip offers masked ROM versions of several of

the highest volume parts, thus giving customers a low

cost option for high volume, mature products.

For information on submitting ROM code, please con-

tact your regional sales ofﬁce.
