Description

General part information

LM8323 Series

The LM8323 key-scan controller is a dedicated device to unburden a host from scanning a matrix-addressed 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 through an I2C-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 LM8323 supports a predefined set of commands. These commands enable a host device to keep control over all functions.
