LM8323 General Description

The LM8323 key-scan controller is a dedicated device to unburden a host from scanning a matrixaddressed keypad. In addition, the LM8323 provides general-purpose I/O expansion, a rotary encoder interface and PWM outputs useful for dynamic LED brightness modulation. It communicates with the host throu.
