Abstract
The invention is a microcircuit configured as a compact, radiation hardened, low-power general purpose I/O expander. The expander may be controlled by an external microcontroller or central processing unit through a serial interface. The expander provides a simple solution to miniaturize static parallel I/O signals using a simplified serial interface such as IC or SPI.
