Overview
FEDL9475-01 Issue Date: Mar.
1, 2010 ML9475 1/3 or 1/4 Duty, 40-Output LCD Driver GENERAL DESCRIPTION The ML9475 is an LCD driver for dynamic display.
It has a function to switch between 1/3 and 1/4 duty.
When 1/4 duty is selected, an LCD of up to 160 segments can be driven directly; when 1/3 duty is selected, an LCD of up to 120 segments can be driven directly.
FEATURES  Logic power supply voltage : 2.
7 to 3.
6 V, 4.
5 to 5.
5 V  Driver power supply voltage : 3.
5 to 5.
5 V  Operatin g temperature : 40 to +105°C  40 segment outputs 1/4 duty : Up to 160 segments can be displayed.
1/3 duty : Up to 120 segments can be displayed.
 Serially interfaces with the CPU using the three signal lines of LOAD, DATA_IN, and CLOCK  Built-in RC oscillator circuit for LCD AC drive (the CLKSEL pin allows selecting an external clock input)  Built-in voltage-dividing resistor for bias voltage generation  Package : 56-pin plastic QFP (QFP56-P-910-0.
