求PT6311B-LQ LQFP52 显示屏驱动芯片参数

PT6311是萤光显示幕（Vavuum Fluorescent Display)的控制/驱野碰动IC，与NEC的UPD16311脚对脚兼容，，能够以1/8~1/16的工作周期驱动萤空锋光显示幕。它内含12个区段输出脚位、8个栅(Grid)输出脚8段栅极输出脚位，足供一般应用之所需。此外PT6311采用三线输入式串列控制介面，相容性高上一且易设计，适合选为单晶片微处理器周边的面板控制、显示器驱动等用途。

特性：

1、多种显示模式（12段/16位~20段/8)

2、控制键扫描（12*4）

3、8级亮度调节电路

4、高电压输出

5、备用5个LED显示LED（20mA Max)

6、通用输入串行接口

7、无需外接驱斗脊晌动电阻

DESCRIPTION 文档资料

PT6311 is a Vacuum Fluorescent Display (VFD) CONTROLLER driven on a 1/8 to 1/16 duty factor housed in

52-pin plastic QFP Package. Twelve segment output lines, 8 grid output lines, 8 segment/grid output

drive lines, one display memory, control circuit, key scan circuit are all incorporated into a single chip to

build a highly reliable peripheral device for a single chip micro computer. Serial data is fed to PT6311

via a three-line serial interface.
