Mobile I/O Companion Supporting Key-Scan, I/O Expansion, PWM, And ACCESS.bus Host Interface

The LM8322 Mobile I/O Companion 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 communicates with the host through an I 2C-compatible ACCESS.bus Interface An interrupt output is available for signaling key-press and key-release events. Communication frequencies up to 400 kHz (Fast-mode) bus speed are supported. The LM8322 supports a predefined set of commands. These commands enable a host device to keep control over all functions.
