DESCRIPTION

The µPD178P018ANote is a device in which the internal mask ROM of the µPD178018A 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 µPD178P018A is a PROM version corresponding to the µPD178004A, 178006A, and 178016A

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)
