Technical coantmesntAsGtill valid 64 LED Driver for Mobile Applications with Error Detection 1 General Description The AS1117 is a pact LED driver for 64 single LEDs or 8 digits of 7-segments. The devices can be programmed via an I²C patible 2-wire interface. Every segment can be individually addressed and updated separately. Only one external resistor (RSET) is required to set the current. LED brightness can be controlled by analog or digital means. The devices include an integrated BCD code-B/HEX decoder, multiplex scan circuitry, segment and display drivers, and a 64-bit memory.
