SERIAL-INTERFACED 10-DIGIT LED CONTROLLER IC WITH KEYSCAN

The UL318 is a compact LED controller and driver thatinterface microprocessors to LED displays through a serial3-wire interface. It drives LED connected in common anodeconfiguration. The UL318 drives up to LEDs in 10segment/7 digit~13 segment/4 digit configuration whilefunctioning from a supply volt LED driver with 17 outputs (14 segments/8 digits~13 segments/4 digits) Output pins connected directly to the LEDs Key-scanning (10 x 2 matrix) 3-wire serial bus interface (CLK, STB, DIO) 8-step dimming circuit to control the overall display brightness Inputs with Schmitt trigger give superior noise ;
