The MB90330/335 series are a line up of high-performance 16-bit MCUs (F2MC-16LX family) with built-in USB macros, supporting USB-Function and simplified USB-Minihost. This allows a USB device to act either as a USB-Host or as a USB-Function. In this way, USB peripheral devices can exchange data without the mediation of a PC. Together with the newly available free USB drivers, Fujitsu aims to target various industrial applications, which are increasingly requiring USB resources.
