PT6311是萤光显示幕(Vavuum Fluorescent Display)的控制/驱动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.
