UPD178P018GC数据手册Renesas中文资料规格书

描述 Description

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)
