STLED316S Serial-interfaced 6-digit LED controller with keyscan
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 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.
Additionally it includes key scanning for an 8x2 key matrix which automatically scans a matrix of up to 16 switches. STLED316S supports numerictype displays and reduces the overall BOM costs through high integration. Also it provides ESD protection of greater than 4 kV HBM.
The LED controller/driver is ideal as a peripheral device to interface the display with a singlechip microcomputer.
技术特性
- LED driver with 14 outputs (8 segments/6 digits)
- 40 mA load current capability for each segment
