产品概述
描述
The STFPC311 is a complete, low-cost, integrated solution for controlling and driving a front panel Vacuum Fluorescent Display (VFD). It is ideal for decreasing power consumption in standby mode by reducing the application standby current to a minimum. It also contains a built-in remote control decoder module.
While in standby mode of operation, a valid key press or signal from the infrared decoder will start a proper power-up.
The STFPC311 integrates a VFD controller with a driver that is run on a 1/8 to 1/16-duty factor. It consists of 12 segment output lines, 8 grid output lines, 8 shared segments/grid output drive lines, a display memory, a control circuit, and a key scan circuit. Serial data is input to the STFPC311 through the SPI interface of a microcontroller (STB, DIN, DOUT, and CLK).
Additionally, this IC can support two general-purpose input switches (SW1 and SW2).
