SD/SDIO/MMC Controller

SD UHS-Ⅰ / eMMC (DDR-mode)―ATA/CF BRIDGE LSI

TE4302

The TE4302 is a controller LSI that supports UHS-I of the latest SD card standard and eMMC DDR mode of eMMC standard and has a function for bridging between these media interfaces and other interfaces such as ATA and CF. Supporting SDR104 ,which is the highest bus speed mode of the UHS-I, the LSI maximizes data transfer performance with the new generation of UHS-I SD memory cards. To suit diversified applications, the host side interface can be configured by a mode change to connect to a 32-bit or 16-bit synchronous CPU interface instead of ATA or CF. Also, the media interface supports two channels.
