1/4 duty and Static Drive General-Purpose LCD Display Driver

Ordering number : ENA1971B LC75890W CMOS LSI 1/4 duty and Static Drive General-Purpose LCD Display Driver http://onsemi.com Overview The LC75890W is the 1/4 duty and static drive general-purpose LCD display driver that can be used for displaying segments for household appliances, home audio visual products, portable devices and other such products under the control of a microcontroller.The LC75890W can drive up to 148 segments directly. In addition the LC75890W can control up to 12 general-purpose output ports. They can control the brightness of the LED backlight of RGB, because they have the PWM output of greatest 3CH built-in. Incorporation of the oscillation circuit helps to reduce the number of external resistors and capacitors required. Incorporation of the LCD drive bias voltage stabilization circuit helps to reduce the capacitors for the LCD drive bias voltage stabilization. Features  Support for 1/4-duty 1/3-bias or static drive techniques under serial data control. When 1/4-duty drive : Capable of driving up to 148 segments When Static drive : Capable of driving up to 37 segments  Support for display segment on, off, or blinking for each segment output pin under serial data control.  Serial data control of the power-saving mode based backup function and the all segments forced off function.  Serial data control of switching between the segment output port and general-purpose output port function.  Support for up to 12 general-purpose output ports  Support.
