UL319C Overview
The UL319C is a pact LED controller and driver that interface microprocessors to LED displays through a serial 3-wire interface. It drives LED connected in mon anode configuration. The UL319C drives up to 80 discrete LEDs in 10 segment/8 digit configuration while functioning from a supply voltage of 5.0V.
UL319C Key Features
- LED driver with 18 outputs (10 segments/8 digits)
- Output pins connected directly to the LEDs
- 3-wire serial bus interface (CLK, STB, DI/O)
- 8-step dimming circuit to control the overall display
- ORDERING INFORMATION
- Inputs with Schmitt trigger give superior noise immunity
- 5.0 V (± 10%) for VDD
- Drives mon-anode LED digits
- Built-in power on reset circuits
- Built-in pull-up resistor (CLK,STB,DI/O)
