MN12511中文资料松下数据手册PDF规格书

■ Overview

The MN12511 is a fluorescent display tube driver LSI. It accepts data for display transferred over a serial interface, generates the digit and/or segment drive signals, and outputs those signals from 16 high-voltage ports.

This LSI allows the number of digits displayed to be increased easily by the cascade connection of additional MN12511 LSIs. Also, the MN12511 does not preassign the outputs to digits or segments, so it can be used with a wide range of display types.

■ Features

• Sixteen high-voltage handling output ports

Number of digit outputs (DGT): 1 to 15 outputs can be arbitrarily assigned

Number of segment outputs (SEG): 1 to 15 outputs can be arbitrarily assigned

• FLP display

• The display mode can be set to any combination of from 1 DGT × 15 SEG to 15 DGT × 1 SEG

• The display on/off state can be controlled from the OE pin.

• Four-wire serial interface (Includes a chip select signal)

• Built-in shift register

• The MN12511 can be connected in cascade.

• Supply voltage

Digital block (VDD): + 4.5 to 5.5 V

High-voltage (Vpp): VDD − 35 V

■ Applications

• Video, audio, and other equipment that uses fluorescent display tubes
