Simple Programmable Logic Devices - SPLDs

A Simple Programmable Logic Device (SPLD) is an IC that can be configured to perform arbitrary logic functions.  An SPLD is very similar to a Complex PLD (CPLD), but an SPLD will have less IO pins and programmable elements, consume less power, and will often require a special programming device to configure, but programming methods are proprietary and may vary by manufacturer.  SPLDs are non-volatile and retain their state after power is removed.
