LM8322 Description

The LM8322 Mobile I/O panion is a dedicated device to unburden a host processor from scanning a matrix-addressed keypad. In addition, the LM8322 provides general-purpose I/O expansion, and PWM outputs useful for dynamic LED brightness modulation. It municates with the host through an I2C-patible ACCESS.bus interface.
