PD78P0308Y
8-BIT SINGLE-CHIP MICROCONTROLLER
Document No. U11832EJ1V0DS00 (1st edition)
Date Published December 1997 N
Printed in Japan
DESCRIPTION
The
μ
PD78P0308Y is a member of the
μ
PD780308Y Subseries of the 78K/0 Series, in which the on-chip mask
ROM of the
μ
PD780308Y is replaced with a one-time PROM or EPROM.
Because this device can be programmed by users, it is ideally suited for system evaluation, small-scale and
multiple-device production, and early development and time-to-market.
Caution
The
μ
PD78P0308YKL-T 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.

TM
Microcontrollers (under planning)
: Reprogrammable (ideally suited for system evaluation)
Note
The internal PROM capacity can be changed by setting the memory size switching register (IMS).
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.
Refer to
1. DIFFERENCES BETWEEN THE
μ
PD78P0308Y AND MASK ROM VERSIONS
for the
difference between the PROM 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.
