DESCRIPTION
The
m
PD78P083(A) is a member of the
m
PD78083 Subseries of the 78K/0 Series products. Comparing with the
m
PD78P083 (standard), more strict quality assurance programs are applied to this product (called Special of the quality
grade in NEC). The
m
PD78P083(A) uses one-time PROM instead of internal ROMs of the
m
PD78081(A) and
m
PD78082(A).
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.
The details of functions are described in the user’s manuals. Be sure to read the following manuals before
designing.

FEATURES
Y
Pin-compatible with mask ROM version (except V
PP
pin)
Y
Internal PROM: 24 Kbytes
Note
m
PD78P083CU(A),
m
PD78P083GB(A): One-time programmable (ideally suited for small-scale production)
Y
Internal high-speed RAM: 512 bytes
Note
Y
Can be operated in the same supply voltage as the mask ROM version (V
DD
= 1.8 to 5.5 V)
Y
Corresponding to QTOP
TM
Microcontrollers (under planning)
Note
The internal PROM and internal high-speed RAM capacities can be changed by setting the internal memory
size switching register (IMS).
Remarks
1.
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).
For the differences between PROM and Mask ROM versions, refer to
Chapter 1. DIFFERENCES
BETWEEN THE

PD78P083(A) AND MASK ROM VERSIONS
