Description
General part information
LM8330 Series
The LM8330 I/O - Expander and Keypad Controller is a dedicated device designed to unburden a host processor from scanning a matrix-addressed keypad and to provide flexible and general purpose, host programmable input/output functions. Three independent Pulse Width Modulation (PWM) timer outputs are provided for dynamic LED brightness modulation.
It communicates with a host processor through an I2C-compatible ACCESS.bus serial interface. It can communicate in Standard (100 kHz) and Fast-Mode (400 kHz) in slave Mode only.
All available input/output pins can alternately be used as an input or an output in a keypad matrix or as a host-programmable general-purpose input or output.
