PD178P018
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD178P018 is a device in which the on-chip mask ROM of the
碌
PD178018 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
PD178P018 is a PROM version corresponding to the
碌
PD178004, 178006, and 178016.
Caution The
碌
PD178P018KK-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 manu-
facture.
For more information on functions, refer to the following User鈥檚 Manuals. Be sure to read them when
designing.

PD178P018KK-T : Reprogrammable (ideally suited for system evaluation)
鈥?Internal high-speed RAM: 1024 bytes
鈥?Internal expansion RAM: 2048 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
PD178P018
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.
