MOS INTEGRATED CIRCUIT
碌
PD78P083
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌PD78P083
is a member of the
碌PD78083
subseries of the 78K/0 series products. It includes an on-chip, 24-Kbyte,
one-time PROM or EPROM.
Because this device can be programmed by users, it is ideally suited for applications involving the evaluation of systems
in development stages, small-scale production of many different products, and rapid development and time-to-market of
a new product.
Caution
The
碌PD78P083DU
does not maintain planned reliability when used in your systems鈥?mass-produced
products. Please use only experimentally or for evaluation purposes during trial manufacture.
The details of functions are described in the user鈥檚 manuals. Be sure to read the following manuals before
designing.

Corresponding to QTOP
TM
Microcontrollers
Note
The internal PROM and internal high-speed RAM capacities can be changed by setting the internal memory size
switching register (IMS).
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).
*
Differs from the mask ROM version in the following points
The same memory mapping as the mask ROM version is enabled by setting the internal memory size switching
register (IMS).
In this document, the term PROM is used in parts common to one-time PROM versions and EPROM versions.
The information in this document is subject to change without notice.
