PD75P036
4-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
µ
PD75P036 is a 4-bit signgle-chip microcontroller that replaced the
µ
PD75028'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.
Detailed functions are described in the followig user's manual. Be sure to read it for designing.

Caution
Internal pull-up/pull-down resistors cannot be specified by mask option as for this device.
Please refer to "Quality grade on NEC Semiconductor Devices" (Document number IEI-1209) published by NEC Corporation
to know the specification of quality grade on e devices and its recommended applications.
The reliability of the EPROM version,
µ
PD75P036KG, is not guaranteed when used in mass-produced application
sets. Please use this device only experimentally or for evaluation during trial manufacture.
The function common to the one-time PROM and EPROM versions is referred to as PROM throughout this document.
