Integrated USB 2.0 on-the-go (OTG) functionality has been added to the 32-bit microcontroller family. Integrated USB OTG helps design engineers easily and cost-effectively address the growing demand for advanced USB connectivity in their end products. The maximum operating frequency for the entire family has been increased to 80 MHz, which further extends the performance reach of this new 32-Bit microcontroller. All family products are supported by development tools, and company provides free source code for USB software stacks and class drivers to enable designers to get a head start on the development of their applications.
