Part Details:

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 SO-24 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 Description display brightness The STLED316S is a compact LED controller and Single external resistor for output current driver that interface microprocessors to LED setting displays through a serial 3-wire interface. It drives Inputs with Schmitt trigger give superior noise LED connected in common anode configuration. immunity The STLED316S drives up to 48 discrete LEDs in A single LED digit output (DIG1_LED) can be 8 segment/6 digit configuration while functioning used to drive up to 8 discrete LEDs from a supply voltage of 5.0V. Additionally it can be used to drive 8 discrete LEDs which form a 8-step dimming circuit to control brightness of part of LED digit. The individual LEDs are wired individual LEDs for LED digit as segments of a digit and brightness of these 5.0 V (± 10%) for VCC individual LEDs can be controlled digitally. The Drives common-anode LED digits maximum segment current for the display digits is set through a single external resistor. Individual Built-in power on reset and soft-start circuits digits may be addressed and updated without re- Available in SO24 package writing the entire display. -40 °C to 85 °C operating temperature range Additionally it includes key scanning for an 8x2 key matrix which automatically scans a matrix of Applications up to 16 switches. STLED316S supports numeric-type displays and reduces the overall BOM costs Set-top-boxes through high integration. Also it provides ESD White goods protection of greater than 4 kV HBM. Home appliances The LED controller/driver is ideal as a peripheral DVD players and VCRs device to interface the display with a singlechip microcomputer. Table 1. Device summary
