The '''MC14500B''' or '''Industrial Control Unit''' ('''ICU''') is a {{arch|1}} [[microprocessor]] designed by [[Motorola]] and released in 1976. Production continued well into the 1990s. The MC14500B was designed as an extremely low cost [[programmable logic controller]] suited for implementing various [[ladder logic]] circuits as replacement for older relay-based systems.

== Architecture ==
{{main|motorola/mc14500#Architecture|l1=MC14500 Architecture}}
The MC14500B had a single 1-bit register to hold the result and supported {{motorola|mc14500/isa|16 different operations}}.

== Packaging ==
The MC14500B came in a few different packages for different specifications.
