USB Applications
Industrial applications are increasingly requiring USB resources. Fujitsu aims to target this demand with the MB90330/335, MB96330 and MB91660 Microcontroller series.
The line-up offers high-performance 16-bit and 32-bit MCUs (F2MC-16LX, F2MC-16FX and FR family) with built-in USB macros, supporting USB-Function and USB-Host. This allows a USB device to act either as a USB-Host or as a USB-Function. Therefore, USB peripheral devices can exchange data without the mediation of a PC. In addition to standard LIN-USART/SPI and I2C interfaces, the MB96330U series offers three channels of CAN to cover all sorts of connectivity requirements.

USB drivers
Developed by Fujitsu and Thesycon, USB drivers are available free of charge from the download site.
The drivers support both USB-Function and USB-Host for MB90330/335, MB96330U and MB91660 series, fulfil standard API norms based on Full-Speed USB specification and can reach a data transfer rate of 1 MByte/s in bulk at full speed.
Furthermore Fujitsu provides software examples including a mass storage class and open source file systems.
