TF/SD/MMC读卡控制芯片MA8121
USB 2.0 SD/MMC Card Reader Controller
Description
The MA8121 is a USB 2.0 Card Reader controller by a highly integrated single chip solution designed to
deliver high-speed data transmission between USB2.0 and SD, SDHC, miniSD, Micro SD(T-Flash),
interfaces specification. The MA8121 is offered with SOP16 package.
MA8121 complies with USB specification Rev. 2.0 and USB Mass Storage Class specification Rev. 1.0.
MA8121 integrates an on-chip clock source which provides stable clock source which can be used to
replace the external 12MHz crystal oscillator. Manufacturers can effectively reduce the BOM and labor
cost on PCBA. MA8121 is the SD card reader with the best C/P value.
