SC6928

SC6928(：S&CIC0311) DESCRIPTION LED Driver IC SC6928 is an LED Controller driven on a 1/7to 1/8 duty factor. Eleven segment output lines, six grid output lines, 1 segment/grid output lines, one display memory, control circuit , key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to SC6928 via a four-line serial interface. Housed in a 28-pin SO Package, SC6928 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages. www.DataSheet4U.com FEATURES CMOS Technology Low Power Consumption Multiple Display Modes Key Scanning 8-Step Dimming Circuitry Serial Interface for Clock, Data Input, Data Output, Strobe Pins Available in 28-Pin, SOP Package APPLICATION Micro-computer Peripheral Device VCR set Combi set BLOCK DIAGRAM Control Serial DI/O CLK STB Data Interface Dispaly Memory SEGMENT DRIVER/ KEY SCAN OUTPUT/ OSC OSC Timing Generator GRID DRIVER R Key Matrix Memory GND SG1/KS1 SG2/KS2 SG3/KS3 SG4/KS4 SG5/KS5 SG6/KS6 SG7/KS7 SG8/KS8 SG9/KS9 SG10/KS10 SG12/GR7 SG13/GR6 SG14/GR5 GR4 GR3 GR2 GR1 Dimming Circuit K1 K2 VDD GND 1 1 SC6928(：S&CIC0311) INPUT/OUTPUT CONFIGURATIONS LED Driver IC The schematic diagrams of the input and output circuits of the logic section are shown below.
