General Description

The UL319 is a compact LED controller and driver that interface microprocessors to LED displays through a serial 4-wire interface.

It drives LED connected in common anode configuration.

The UL319 drives up to 128 discrete LEDs in 16 segment/8 digit configuration while functioning from a supply voltage of 5.0V.

Overview

UNISONIC TECHNOLOGIES CO.,LTD.

UL319 Preliminary LINEAR INTEGRATED CIRCUIT SERIAL-INTERFACED 16-DIGIT LED CONTROLLER IC WITH KEYSCAN.

Key Features

  • LED driver with 24 outputs (16 segments/8 digits).
  • Output pins connected directly to the LEDs.
  • Key-scanning (8 x 4 matrix).
  • 3-wire serial bus interface (CLK, STB, DI/O).
  • 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,DOUT).
