UPD178P018A Description
The µ PD178P018ANote is a device in which the internal mask ROM of the µ PD178018A 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 µ PD178P018A is a PROM version corresponding to the µPD178004A, 178006A, and 178016A.
UPD178P018A Key Features
- Pin-patible 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)
