LC75809PT Overview
ENA1976 LC75809PT CMOS IC 1/4 and 1/3-Duty General-Purpose LCD Display Driver http://onsemi. Overview 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...
LC75809PT Key Features
- Serial data input supports CCB format munication with the system controller. (Support 3.3V and 5V 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 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 mon 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
