1 / 4 page Data Brief For further information contact your local STMicroelectronics sales office. February 2007 Rev 1 1/4 4 Features ■ LED driver with 14 outputs (8 segments / 6 digits) ■ 40mA load current capability for each segment ■ Outputs connect directly to the LEDs or can be open-drain ■ Key-scanning (8x2 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 ■ 5.0V (± 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 Applications ■ Set Top Boxes ■ White goods ■ Home appliances ■ DVD players, VCRs Description The STLED316S is a compact LED controller and driver that interface microprocessors to LED displays through 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 5.0V. 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 re- writing the entire display. Additionally it includes key scanning for an 8x2 key matrix which automatically scans a matrix of up to 16 switches. STLED316S supports numeric- type displays and reduces the overall BOM costs through high integration. Also it provides ESD protection of greater than 2kV HBM. The LED controller/driver is ideal as a peripheral device to interface the display with a singlechip microcomputer.
