PD78P018F
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD78P018F is a member of the
碌
PD78018F Subseries within the 78K/0 Series. The internal mask ROM of
the
碌
PD78018F is replaced with one-time PROM or EPROM.
Because the
碌
PD78P018F can be programmed by users, it is 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 new products.
Caution
The

PD78P018FDW and 78P018FKK-S are not guaranteed to maintain the reliability level required
for mass production of the customer鈥檚 devices.
purposes during trial manufacture.
Detailed function descriptions are provided in the following user鈥檚 manuals. Be sure to read them before
designing.
Use only experimentally or for evaluation

Notes 1.
The capacities of internal PROM and internal high-speed RAM can be changed by means of the internal
memory size switching register (IMS).
2.
The capacity of the internal expansion RAM can be changed by means of the internal expansion RAM size
switching register (IXS).
Remarks 1.
QTOP Microcontroller is a general term for microcontrollers that incorporate one-time PROM and are totally
supported by NEC's programming service (from programming to marking, screening and verification).
2.
For differences between the PROM version and mask ROM versions, refer to
1. DIFFERENCES
BETWEEN
碌
PD78P018F AND MASK ROM VERSIONS.
In this document, the term PROM is used in parts common to one-time PROM versions and EPROM versions.
