DESCRIPTION

The µPort Saver memories need no serial ports or special hardware and connect to the processor memory bus. Replacing bytewide data memory, the µPort Saver uses bytewide memory control functions, takes a fraction of the board space and consumes much less power. Replacing serial memories, the µPort Saver provides all the serial benefits, such as low cost, low power, low voltage, and small package size while releasing I/Os for more important uses.
