LC75809PT中文资料LC75809PT: Microprocessor-controlled LCD Driver, 1/4 Duty and 1/3 Duty, General-purpose数据手册ONSEMI规格书

描述 Description

The LC75809PT is the 1/4 duty and 1/3 duty general-purpose microprocessor-controlled LCD driver that can be used in applications such as frequency display in products with electronic tuning. In addition to being able to drive up to 352 segments directly, the LC75809PT can also control up to 12 general-purpose output ports. Because it has the PWM output of a maximum of 6ch, the brightness control of the LED backlight of RGB x 2 can be done. Incorporation of an oscillation circuit helps to reduce the number of external resistors and capacitors required.

特性 Features

Support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under serial data control.When 1/4-duty : Capable of driving up to 352 segmentsWhen 1/3-duty : Capable of driving up to 267 segments
Serial data input supports 'computer control bus' format communication with the system controller. (Support 3.3 V and 5 V operation)
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 for the PWM output function of a maximum of 6ch. (It can output from the general-purpose output port).
Support for clock output function of 1ch. (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 switching between the internal oscillator operating mode and external clock operating mode.
High generality, since display data is displayed directly without the intervention of a decoder circuit.
Built-in display contrast adjustment 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)
