MOS Integrated Circuit
µPD75P036
4-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD75P036 is a 4-bit signgle-chip microcontroller that replaced the µPD75028's on-chip ROM with
one-time PROM or EPROM. Because this device can operate at the same supply voltage as its mask
version, 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
different products and time-to-market of a new product. The EPROM version is programmable, erasable,
and reprogrammable, and is suited for the evaluation of application systems.
