SERIAL-INTERFACED

10-DIGIT LED CONTROLLER

IC WITH KEYSCAN



DESCRIPTION

The UL318 is a compact LED controller and driver that

interface microprocessors to LED displays through a serial

3-wire interface. It drives LED connected in common anode

configuration. The UL318 drives up to LEDs in 10

segment/7 digit~13 segment/4 digit configuration while

functioning from a supply voltage of 5.0V.



FEATURES

* 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

immunity

* 5.0 V (± 10%) for VDD

* Drives common-anode LED digits

* Built-in power on reset circuits

* Built-in pull-up resistor (CLK,STB,DIO)
