STFPC311 is a low-cost, integrated front panel controller/driver from STMicroelectronics. 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.
The STFPC311 is a complete, low-cost integrated solution for controlling and driving a front panel Vacuum Fluorescent Display (VFD). It is designed to decrease power consumption in standby mode by reducing application standby current to a minimum. The device integrates a VFD controller with a driver that operates on a 1/8 to 1/16-duty factor, along with a built-in remote control decoder module.
