UL316 Datasheet 6-DIGIT LED CONTROLLER

Manufacturer: Unisonic Technologies

Overview: UNISONIC TECHNOLOGIES CO.,LTD UL316 LINEAR INTEGRATED CIRCUIT SERIAL-INTERFACED 6-DIGIT LED CONTROLLER IC WITH KEYSCAN.

Datasheet Details

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.

S.
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.
