NJU3505

PRELIMINARY

4-BIT SINGLE CHIP MICRO CONTROLLER

GENERAL DESCRIPTION

The

NJU3505

is the C-MOS 4-bit Single Chip Micro

Controller consisting of the 4-bit CPU Core, Input / Output

Selectable I/O ports, Program ROM, Data RAM, Dual

Timer/Counter, 8-bit Serial Interface, 8-bit A/D Converter,

and Oscillator Circuit (CR or Ceramic or X'tal). It realizes

the control for home appliances or toys by only few

external components.

The

NJU3505

is suitable for battery operated appliances

because of low operating current, wide operating voltage

range, and STANDBY function (HALT mode).
