The MC2701 is a compact LED controller and driver that interface microprocessors to LED display throuth a serial 3-wire interface. It drives LED connected in common anode configuration. The MC2701 drives up to 48 discreete LEDs in 8 segment / 6 digit configuration while functioning from a supply voltage 4.5V~5.5V. Additionally it can be used to drive 8 discrete LEDs which form a part of LED digit. The individual LEDs are wired as segment of a digit and brightness of individual LEDs can be controlled digitally. The maximum segment current for the display digits is set through a single external resisteor. Individual digits may be addressed and updated without re-writing the entire display. Additionally it includes key scanning for an 8 x 2 key matrix which automatically scans a matrix of up to 16 switches. MC2701 supports numeric-type displays and reduces the overall BOM costs through high integration. Also it provides ESD protection of greater than 4KV HBM. The LED controller / driver is ideal as a peripheral device to interface the display with a singlechip microcomputer.
