PD178P018A
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD178P018A
Note
is a device in which the internal mask ROM of the
碌
PD178018A 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-lot and multiple-
device production, and early development and time-to-market.
The
碌
PD178P018A is a PROM version corresponding to the
碌
PD178004A, 178006A, and 178016A.
Note
Caution
Under development
The
碌
PD178P018AKK-T does not maintain planned reliability when used in your system鈥檚 mass-
produced products. Please use only experimentally or for evaluation purposes during trial manufacture.
For more information on functions, refer to the following User鈥檚 Manuals. Be sure to read them when
designing.

PD178018A Subseries User鈥檚 Manual: To be prepared
78K/0 Series User鈥檚 Manual Instruction: U12326E
FEATURES
鈥?Pin-compatible with mask ROM version (except for V
PP
pin)
鈥?Internal PROM: 60 Kbytes

碌
PD178P018AKK-T : Reprogrammable (ideally suited for system evaluation)
鈥?Internal high-speed RAM: 1 024 bytes
鈥?Internal expansion RAM: 2 048 bytes
鈥?Buffer RAM: 32 bytes
鈥?Can be operated in the same power supply voltage as the mask ROM version
(During PLL operation: V
DD
= 4.5 to 5.5 V)
The electrical specifications (power supply current, etc.) and PLL analog specifications of the
碌
PD178P018A differ
from that of mask ROM versions. So, these differences should be considered and verified before application sets
are mass-produced.
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.
