PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µ PD178P018A
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD178P018ANote is a device in which the internal mask ROM of the µPD178018A is replaced with a onetime 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 µPD178P018A is a PROM version corresponding to the µPD178004A, 178006A, and 178016A.
N ote
Caution
Under development
The µPD178P018AKK-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. µ PD178018A Subseries User's Manual: To be prepared 78K/0 Series User's Manual Instruction: U12326E
FEATURES
· Pin-compatible with mask ROM version (except for VPP pin) · Internal PROM: 60 Kbytes · µPD178P018AGC : One-time programmable (ideally suited for small-lot production) · µPD178P018AKK-T : Reprogrammable (ideally suited for system evaluation) · Internal high-speed RAM: 1 024 bytes · Internal expansion RAM: 2 048 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 µPD178P018A 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.
