SC16315

SC16315 VFD CONTROLLER/DRIVER DESCRIPTION The SC16315 is a FIP (Fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is driven on a 1/4 or 1/12 duty factor. It has 16 segment outputs, 4 grid outputs, 8 segment/grid outputs, a display memory, a control circuit, and a key scan circuit. Serial data comes from a three-line serial interface. This FIP controller/driver is ideal as a peripheral device for a single-chip microcomputer. QFP44-10 x10-0.8(S) FEATURES * Multiple display modes (16-segment & 12-dight 4-digit). * Key scanning (16x2 matrix). * Dimming circuit (eight steps). * High-voltage output (VDD – 35V max). * LED ports (4 chs., 20 mA max). * No external resistors necessary for driver outputs (P-ch open-drain + pull-down resistor output) * Serial interface (CLK, STB, DIN, DOUT) to 24-segment & ORDERING INFORMATIONS Device SC16315 Package QFP-44-10 X 10-0.8(S) APPLICATIONS * Microcomputer peripheral device BLOCK DIAGRAM www.DataSheet4U.com Seg1/ KS1 Segment Driver 7 6 8 9 DIN DOUT Serial Data Interface Command Decoder Dimming Circuit 14 Seg16/ KS16 Seg17/ Grid12 29 31 CLK STB Display Memory 24 bits Output Latch Data Selector Multiplexed Driver Timing Generator Seg24/ Grid5 38 42 39 5 OSC OSC Key Data Memory 4-Bits Latch Grid4 12 Bits Shift Register Grid Driver Grid1 LED1 LED4 K1 K2 VDD VSS VEE 1 4 10 11 43 44 30 HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.0 2008.12.16 Page 1 of 11 S...
