MAX6955AAX+ - Maxim Integrated Function Overview

The MAX6955AAX+ is a 2-wire interfaced LED Display Driver with I/O expander and key scan. The MAX6955 is a compact display driver that interfaces microprocessors to a mix of 7-segment, 14-segment and 16-segment LED displays through an I²C-compatible 2-wire serial interface. The MAX6955 drives up to 16 digits 7-segment, 8 digits 14-segment, 8 digits 16-segment or 128 discrete LEDs, while functioning from a supply voltage as low as 2.7V. The driver includes five I/O expander or general-purpose I/O (GPIO) lines, some or all of which can be configured as a key-switch reader. The key-switch reader automatically scans and debounces a matrix of up to 32 switches. Included on chip are full 14- and 16-segment ASCII 104-character fonts, a hexadecimal font for 7-segment displays, multiplex scan circuitry, anode and cathode drivers and static RAM that stores each digit. The maximum segment current for the display digits is set using a single external resistor.
