MC14500B中文资料摩托罗拉数据手册PDF规格书

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.
