PT16514 - LCD Driver

Datasheet Summary

Description

The PT16514 is 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller.

The PT16514 can drive an LCD with up to 216 segments directly.

The PT16514 can also control up to 8 generalpurpose output ports.

Features

  • Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.
  • Up to 216 segments for 1/4 duty drive can be displayed.
  • 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 OSC circuit.
  • The INHB pin can.
