1/3, 1/4-Duty General-Purpose Display Driver
LC75835W 1/3, duty general-purpose display driver that used displaying segments mobile devices other such products under control microcontroller. addition being able directly drive segments, LC75835W also control general-purpose output ports. incorporates oscillation circuit that reduces external resistors capacitors used oscillation.
Features
Either duty selected with serial control data. duty drive: segments driven duty drive: segments driven Either bias selected with serial control data. off, blinking each segment with serial control data. Serial data control display switching 40-bit units. general rule, display switched segment-units.) Serial data control current on/off drive bias voltage generation divider resistors. Serial data control power-saving mode based backup function segments forced function. Serial data control switching between segment output port general-purpose output port functions. Buzzer control signals channel) output from general-purpose output port. Serial data control frame frequency common segment output waveforms. Serial data control segment blinking frequency. Serial data control switching between internal oscillator operating mode external clock operating mode. Serial data input supports CCB* format communication with system controller. Independent VLCD driver block (VLCD voltage range volts without regard logic block power supply VDD). allows display forced state. Incorporation oscillator circuit
