The PT16576 is 1/3 duty and 1/4 duty generalpurpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The PT16576 can drive an LCD with up to 340 segments directly. The PT16576 can also control up to 8 general-purpose output ports.

FEATURES


● Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.

●· Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.

● Up to 258 segments for 1/3 duty drive and 340 segments for 1/4 duty drive can be displayed.

● Serial interface for clock, Data Input, Data Output, Strobe pins.

● Serial data control of the power-saving mode based backup function and all the segments forced off function.

● Serial data control of switching between the segment output port and the general-purpose output port functions.

● Serial data control of frame frequency for common and segment output waveforms.

● High generality, since display data is displayed directly without decoder intervention.

● Built-in display contrast adjustment circuit

● Independent VLCD for the LCD driver block

● The /INH pin can force the display to the off state.

● RC oscillator circuit

● AEC-Q100 Grade2 Compliant for Automotive Applications

● Package - LQFP100
