SERIAL-INTERFACED

6-DIGIT LED CONTROLLER

IC WITH KEYSCAN



DESCRIPTION

The UL316 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 UL316 drives up to 48 discrete LEDs in

8 segment/6 digit configuration while functioning from a

supply voltage of 5.0V.

SOP-24



FEATURES

* LED driver with 14 outputs (8 segments/6 digits)×40 mA

load current capability for each segment

* Output pins connected directly to the LEDs or can be

open-drain

* Key-scanning (8 x 2 matrix)

* 3-wire serial bus interface (CLK, STB, DIN/DOUT)

* 8-step dimming circuit to control the overall display

brightness

* Single external resistor for output current setting

* Inputs with Schmitt trigger give superior noise

immunity

* A single LED digit output (DIG1_LED) can be used to

drive up to 8 discrete LEDs

* 8-step dimming circuit to control brightness of

individual LEDs for LED digit

* Drives common-anode LED digits

* Built-in power on reset and soft-start circuits
