PT16576 Overview
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.
PT16576 Key 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 mon 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
