DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD178P018
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD178P018 is a device in which the on-chip mask ROM of the µPD178018 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 multipledevice production, and early development and time-to-market. The µPD178P018 is a PROM version corresponding to the µPD178004, 178006, and 178016. Caution The µPD178P018KK-T does not maintain planned reliability when used in your system's massproduced products. Please use only experimentally or for evaluation purposes during trial manufacture. For more information on functions, refer to the following User's Manuals. Be sure to read them when designing.

FEATURES
· Pin-compatible with mask ROM version (except for VPP pin) · Internal PROM: 60 Kbytes · µPD178P018GC : One-time programmable (ideally suited for small-lot production) · µPD178P018KK-T : Reprogrammable (ideally suited for system evaluation) · Internal high-speed RAM: 1024 bytes · Internal expansion RAM: 2048 bytes · Buffer RAM: 32 bytes · Can be operated in the same power supply voltage as the mask ROM version (During PLL operation: VDD = 4.5 to 5.5 V)
The electrical specifications (power supply current, etc.) and PLL analog specifications of the µPD178P018 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.
