NJU3101
PRELIMINARY
4-BIT SINGLE CHIP TINY CONTROLLER
s GENERAL DESCRIPTION
The NJU3101 is the C-MOS 4-bit Single Chip Tiny
Controller consisting of the 4-bit CPU Core, Input / Output
Selectable I/O ports, Program ROM, Data RAM, and
Oscillator Circuit (CR or Ceramic or X'tal). It is packaged
in 16-pin package (DIP or DMP form). Therefore it
provides a cost and space effective replacement with only
few external components for control-logic circuit using
standard logic ICs (i.e. 74HC) or other small controllers.
The NJU3101 is suitable for battery operated
appliances because of low operating current, wide
operating voltage range, and STANDBY function (HALT
mode).
