UPD178P018GC中文资料瑞萨数据手册PDF规格书

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 multiple device production, and early development and time-to-market.

The µPD178P018 is a PROM version corresponding to the µPD178004, 178006, and 178016.

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)
