Description

The MA8601 is a high performance solution for USB 2.0 High Speed 4-port hub controller with

fully compliant with Universal Serial Bus Specification 2.0. The controller inherits advanced serial

interface technology to consume the least power when 4 DS (downstream) ports function

simultaneously.

MA8601 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.

MA8601 supports SSOP28 package targets at mainstream stand along 4 ports Hub market.
