FUMAN ELECTRONICS SC6961
SC6961 is an LED Controller driven on a 1/7to 1/8 duty factor. Command 1: Display Mode Setting Commands SC6961 provides 2 display mode settings as shown in the diagram below: As stated earlier a command is the first one byte ( b0 to b7 ) transmitted to SC6961 via the DIN Pin when STB is LOW.DESCRIPTION
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 SC6961 via a four-line serial interface. Housed in a 32-pin SO Package, SC6961 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.FEATURES
