STLED316S

STLED316S Serial-interfaced 6-digit LED controller with keyscan Features ■ 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 Applications ■ Set-top-boxes ■ White goods ■ Home appliances ■ DVD players and VCRs Table 1. Device summary SO-24 Description The STLED316S 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 5.0V. 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 individu...
