DriverCore: Atmel Optimized

DriverCore: Atmel Optimized
Specific USB controllers support details
» A part of DriverCore: USB CDC/Modem/DFU/Serial Drivers solution
The DriverCore product line implements various class specifications set by the USB-IF. These classes include Communication Device Class (CDC) with the ACM, ECM, EEM specifications, USB-to-Serial implementation, Device Firmware Upgrade (DFU) protocol, and others.

  DriverCore is optimized and tested across Atmel's USB controllers.

The table below shows Atmel's USB device controllers, detailing their support capabilities for various USB specifications. The controller's available resources (specifically the number of endpoints) is the restricting factor for supporting various USB classes.
