PD78P018FY
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD78P018FY is a member of the
碌
PD78018FY Subseries of 78K/0 Series products. The internal mask ROM
of the
碌
PD78018FY is replaced with one-time PROM or EPROM.
Because the
碌
PD78P018FY 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 new products.
Caution
The
碌
PD78P018FYDW and 78P018FYKK-S are not guaranteed to maintain the reliability level
required for mass production of the customer's devices. Please use only experimentally or for
evaluation purposes during trial manufacture.
Detailed function descriptions are provided in the following user's manuals. Be sure to read them before designing.

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 which incorporate one-time PROM and are totally
supported by NEC's programming service (from programming to marking, screening, and verification).
2.
For the differences between the PROM version and mask ROM versions, refer to
1. DIFFERENCES BETWEEN
THE
碌
PD78P018FY AND MASK ROM VERSIONS.
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.
