1 / 8 page MOTOROLA CMOS LOGIC DATA MC14500B 306 Industrial Control Unit 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. • 16 Instructions • DC to 1.0 MHz Operation at VDD = 5 V • On–Chip Clock (Oscillator) • Executes One Instruction per Clock Cycle • 3 to 18 V Operation • Low Quiescent Current Characteristic of CMOS Devices • Capable of Driving One Low–Power Schottky Load or Two Low–Power TTL Loads over Full Temperature Range BLOCK DIAGRAM DATA X1 X2 I0 I1 I2 I3 RST 3 14 13 7 6 5 4 1 INST REG OSC D C IEN LU D C RESULT REG.
