The MC 14500 Industrial Control Unit (ICU) is a CMOS one-bit microprocessor designed by Motorola for simple control applications in 1977. It was packaged in a 16-pin DIP and normally ran at 1 MHz with 5 V and only 5 μA. If higher performance was needed, it could run as fast as 4 MHz by increasing the voltage to 15 V. It was inexpensive for the era, available at launch for $7.58 in 100-unit lots.
