AU6433 is Alcor’s USB 2.0 SD/MMC/MS/XD integrated card reader for laptops. It makes use of 48 MHz clock signal and 3.3V/1.8V rails, which are already available on the motherboard. When used standalone, a XO and 2 LDOs must be provided. When there is no card detection signal, it will not connect to USB and will have very little power consumption.
Some footprints on this PCB are slightly misaligned, but should still be solderable. U2 = 3.3V LDO, U3 = 1.8V LDO, U4 = SiT2001B 48 MHz MEMS oscillator. C1 = C6 = 1uF, C7 = C8 = 10uF, rest are 4.7uF. R1 = 4.7k (reset pull-up), R2 = 330ohm. Fuse should be 500mA but anything above 200mA should work. X2 = 3M SD-RSMT-2-MQ-WF.
