MOS Integrated Circuit

PD78P322

16/8-BIT SINGLE-CHIP MICROCONTROLLER

The

PD78P322 is a version provided by replacing the

PD75322's internal mask ROM with one-time PROM

or EPROM.

Because the one-time PROM version is programmable only once by users, it is ideally suited for small-scale

production of many different products, and rapid development and time-to-market of application sets.

The EPROM version is reprogrammable, and suited for the evaluation of systems.

The

PD78P322K, which is the EPROM version, does not maintain planned reliability when

used in mass-produced products. Please use only experimentally or for evaluating functions

during trial manufacture.

Functions are described in detail in the following user's manual. Be sure to read it for designing.

PD78322 User's Manual: IEU-1248

FEATURES

•

PD78322 compatible

• For mass-production, the

PD78P322 can be replaced with the

PD78322 which incorporates mask

ROM

•

Internal PROM: 16,384

8 bits

• Programmable once only (one-time PROM version without window)

• Erasable with ultraviolet rays and electrically programmable (EPROM version with window)

•

PROM programming characteristics:

PD27C256A compatible

The

PD78P328 is a QTOP

microcontroller

Remark

QTOP microcontroller is a general term for microcontrollers which incorporate one-time PROM, and

are totally supported by NEC's programming service (from programming to marking, screening, and

verification).
