MA8621
USB 2.0 High Speed 3-Port Hub with SD Reader Controller
Description
The MA8621 is a high performance solution for USB 2.0 High Speed 3-port hub with SD card controller which is fully
compliant with Universal Serial Bus Specification 2.0. The controller inherits advanced serial interface technology to
consume the least power when 3 DS (downstream) ports function simultaneously.
The MA8621 is an innovation that integrates function to combine USB 2.0 Hub and SD card reader. The reader
complies with SD, SDHC, SDXC and MMC card specification. With single IC, MA8621 provides system solution targeting
the multi-media set top box for multiple USB ports and reader application.
MA8621 adapt Single Transaction Translator (STT) and Ganged power management to achieve cost effective purpose.
Users can also implement multiple Hub configuration options through external EEPROM.
MA8621 provides QFN-40 package.
