GP521 Overview
The GP521 is a general purpose controller/memory chip intended for use with audio signal path circuits in programmable hearing instruments. The GP521 uses a flexible munication standard which allows room for future growth in programmable functions for hearing instruments. The munication with the program unit is over a bi-directional serial data link.
