MOTOROLA CMOS LOGIC DATA
MC14500B
306
The MC14500B Industrial Control Unit (ICU) is a single–bit CMOS
processor. The ICU is designed for use in systems requiring decisions based
on successive single–bit information. An external ROM stores the control
program. With a program counter (and output latches and input multiplexers,
if required) the ICU in a system forms a stored–program controller that
replaces combinatorial logic. Applications include relay logic processing,
serial data manipulation and control. The ICU also may control an MPU or be
controlled by an MPU.
