VFD/LED Front Panel Controllers

ST's panel controllers integrate VFD driving, key-scan matrix, LED driving, infrared (IR) remote control decoding and a real-time clock (RTC) into one device. All the functions are programmable using the I²C bus. Low power consumption is achieved during standby operation. The controller provides standby power management to the main chipset. The pin assignments and application diagrams are optimized for easy PCB layout and cost savings.
