The is a FIP (Fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is driven or 1/11 duty factor. It consists of 11 segment output lines, 6 grid output lines, 5 segment/grid output drive lines, a display memory, a control circuit, and a key scan circuit. Serial data is input to the SC16312 through a three-line serial interface. This FIP controller/driver is ideal as a peripheral device for a single-chip microcomputer.
* Multiple display modes 4-digit). * Key scanning (6x4 matrix). * Dimming circuit (eight steps). * High-voltage output (VDD 35V max). * LED ports (4 chs., 20 mA max). * General-purpose input port (4 bits) * No external resistors necessary for driver outputs (P-ch open-drain + pull-down resistor output) * Serial interface (CLK, STB, DIN, DOUT)

Maximum power consumption PMAX. = FIP driver dissipation + RL dissipation + LED driver dissipation + dynamic power consumption Where segment current = 3mA, grid current = 15mA, and LED current = 20mA, FIP driver dissipation = number of segments 6 + number of grids/(number of grids 30(mW) RL dissipation = (VDD-VEE) /50 x (number of segments + 1)(mW) LED driver dissipation = number of LEDs x 20(mW) Dynamic power consumption = VDD x 5(mW)
Example Where VEE = -25V, VDD = 5V, and in 16-segment and 6-digit modes, FIP driver dissipation 122 RL dissipation = 306 LED driver dissipation = 80 Dynamic power consumption 25 Total 553 Mw
