NJU3000 Series
- 1 -
■ GENERAL DESCRIPTION
The NJU3000 series is a C-MOS 4-bit Single Chip Tiny/Micro Controller consisting of Program ROM, Data
RAM, I/O ports, Timers (except the NJU3100 series), Serial Interface (except the NJU3100 series), Interrupt
Control Circuits (except the NJU3100 series), 8-bit A/D Converter (the NJU3503/04/05), and Oscillator Circuit
(CR, Ceramic or X’tal), etc. It is contained in 16-pin (the NJU3101), 22-pin (the NJU3102), 20-pin (the
NJU3501), 24-pin (the NJU3502), 28- or 30-pin (the NJU3503), 42- or 44-pin (the NJU3504/05) package.
The NJU3000 series realizes the home appliances or toys control by a few external components.
The CPU in the NJU3000 series is our original architecture. It contains Arithmetic Logic Unit (ALU)
perfor ming binary additional and logical operations, Ac cum ulator (AC), four 4-bit general purpose r egisters and
Stack (8 levels) that allows subroutine nesting or interrupt.
The NJU3000 series is s uitable for various applic ations becaus e of abundant ins truction s et (59 instruc tions:
the NJU3500 series, 58 instructions : the NJU3100 series), f ast operation (m inim um ins truction exec uting time
1.5µs/fOSC=4MHz), wide operating voltage range (2.4V to 5.5V), low operating current, and STANDBY function.
The NJU3151/52, NJU3551/52/53/54/55 (OTP version) are prepared for the final evaluation before making
mask, small-quantity production and pre-production. The function and package of the NJU3151/52,
NJU3551/52/53/54/55 (OTP version) are compatible with the NJU3101/02, NJU3501/02/03/04/05 (MASK
version).
