Description:
...The μPD75P036 is a 4-bit signgle-chip microcontroller that replaced the μPD75028s on-chip ROM withone-time PROM or EPROM. Because this device can operate at the same supply voltage as its maskversion, it is suited for preproduction in development stage or small-scale production.The one-time PROM version is programmable only once and is useful for small-scale production of many... ...and reprogrammable, and is suited for the evaluation of application systems.Detailed functions are described in the followig users manual. Be sure to read it for designing. μPD75028 Users Manual: IEU-1280FEATURES... ...MD0-MD3 (P30-P33) These pins select operation mode when program memory is written/verified.P40-P43 (Lower 4) These pins input/output 8-bit data when program memory is written/verified.P50-P53 (Upper 4)VDD Power supply voltage application pin....
