Silan Semiconductors VFD CONTROLLER/DRIVER The SC16311 is a FIP (Fluorescent Indicator Panel or Vacuum Fluorescent Display) controller/driver that is driven on a 1/8- to 1/16 duty factor. It consists of 12 segment output lines, 8 grid output lines, 8 segment/grid output drive lines, a display memory, a control circuit, and a key scan circuit. Serial data is input to the SC16311 through a three-line serial interface. This FIP controller/driver is ideal as a peripheral device of a single-chip microcomputer. SC16311 FEATURES · Many display modes (12-segment & 16-digit to 20-segment & 8-digit) · Key scanning (12x4 matrices) · Dimming circuit (eight steps) · High-voltage output (VDD-35 V max). · LED ports (5 chs., 20 mA max). · General-purpose input port (4 bits) · No external resistor necessary for driver outputs (P-ch open-drain + pull-down resistor output) · Serial interface (CLK, STB, DIN, DOUT) QFP-52-14 x 14-1.0 PIN CONFIGURATION LED1 LED2 LED3 LED4 LED5 Grid1 Grid2 Grid3 OSC Grid4 41 52 SW1 1 SW2 2 SW3 3 SW4 4 D OUT 5 D IN 6 IC 7 CLK 8 STB 9 KEY1 10 KEY2 11 KEY3 12 KEY4 13 14 VDD 15 Seg1/KS 1 16 Seg2/KS 2 17 Seg3/KS 3 18 Seg4/KS 4 19 Seg5/KS 5 20 Seg6/KS 6 21 Seg7/KS 7 22 Seg8/KS 8 23 Seg9/KS 9 24 Seg10/KS10 25 Seg11/KS11 26 Seg12/KS12 51 50 49 48 47 46 45 44 43 42 40 39 Grid6 38 Grid7 37 Grid8 36 Seg20 /Grid9 35 Seg19 /Grid10 34 V EE Grid5 33 V DD 32 Seg18/Grid11 31 Seg17/Grid12 30 Seg16/Grid13 29 Seg15/Grid14 28 Seg14/Grid15 27 Seg13/Grid16 V DD V SS SC16311 HANGZHOU SILAN MICROELECTRONICS CO.,LTD.
