DESCRIPTION
The μPD78P083 is a member of the μPD78083 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
μ
PD78P083DU does not maintain planned reliability when used in your systems’ mass-produced
products. Please use only experimentally or for evaluation purposes during trial manufacture.
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
μPD78P083DU: Reprogrammable (ideally suited for system evaluation)
μPD78P083CU, μPD78P083GB: 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
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.
