Description

General part information

LM8328 Series

The LM8328 GenI/O - Expander and Keypad Controller is a dedicated device 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 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.
