Features & Applications

The STLED316SMTR 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 STLED316S drives up to 48 discrete LEDs in 8 segment/6 digit Configuration while functioning from a supply voltage of 5.0 V.

Additionally it can be used to drive 8 discrete LEDs which form a part of LED digit. The individual LEDs are wired as segments of a digit and brightness of these individual LEDs can be controlled digitally. The maximum segment current for the display digits is set through a single external resistor. Individual digits may be addressed and updated without rewriting the entire display.


  • 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)
  • Low power consumption in standby mode
  • 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
  • 5.0 V (± 10%) for VCC
  • Drives common-anode LED digits
  • Built-in power on reset and soft-start circuits
  • Available in SO24 package
  • -40 °C to 85 °C operating temperature range


  • Set-top-boxes
  • White goods
  • Home appliances
  • DVD players and VCRs
