NJU3504
PRELIMINARY
4-BIT SINGLE CHIP MICRO CONTROLLER
s GENERAL DESCRIPTION
The NJU3504 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 NJU3504 is suitable for battery operated appliances
because of low operating current, wide operating voltage
range, and STANDBY function(HALT mode).
