2.0 PIC16C55X(A) 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 PIC16C55X(A) Product

Identification System section at the end of this data

sheet. When placing orders, please use this page of the

data sheet to specify the correct part number.

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® and PROMATE®

programmers both support programming of the

PIC16C55X(A).

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. 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

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 pat-

terns have stabilized. The devices are identical to the

OTP devices but with all EPROM locations and config-

uration options already programmed by the factory.

Certain code and prototype verification procedures

apply before production shipments are available.

Please contact your 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

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.
