NEC MOS DIGITAL INTEGRATED CIRCUIT
4-BIT SINGLE CHIP MICROCOMPUTER
INTRODUCTION
The NEC uCOM - 43 is a 4- bit parallel central processing unit
that forms a single chip microcomputer especially suited for a
broad range of low cost and sophisticated controller
applications.
The uCOM-43 contains all the necessary system functional
blocks for a single chip microcomputer, including a 4- bit
parallel ALU, 2 , 000 by 8 - bit program ROM, 96 by 4-bit data RAM,
35 input/output channels, a programmable interval timer ,
interrupt handling circuits, a clock generator and control
circuits.
The instruction set of the uCOM -43 includes 80 powerful
instructions. The instruction set features controller- oriented
functions and efficient use of program memory , via a variety of
multi-function instructions, powerful I/O instructions, and a
number of bit manipulation and test-and-skip instructions .
The extensive flexibility and processing capabilities
provided by the uCOM -43 will enable advanced microcomputerization
of both industrial and non- industrial controller applications.
