產(chǎn)品信息

The LC75890W is 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, and the LC75890E can drive up to 132 segments directly. In addition the LC75890W can control up to 12 general-purpose output ports. It 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.

Support for 1/4-duty 1/3-bias or static drive techniques under serial data control.
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 the PWM output function of a maximum of 3ch. (It can output from the general-purpose output port ).
Serial data control of the frame frequency of the common and segment output waveforms.
Serial data control of the segment blinking frequency.
Serial data control of switching between the internal oscillator operating mode and external clock operating mode.
Serial data input supports 'computer control bus' format communication with the system controller.
Independent VLCD for the LCD driver block.
Built-in LCD drive bias voltage stabilization circuit.
The INH pin allows the display to be forced to the off state.
Incorporation of an oscillator circuit. (Incorporation of resistor and capacitor for an oscillation)
