Atmel's family of 8-bit microcontrollers with integrated USB controller support a wide range of USB applications: high-end keyboards, mice, phone accessories, toys, serial adapters and industrial equipment.
Atmel’s 8‑bit flash microcontrollers integrate a USB controller for a wide range of applications such as keyboards, mice, industrial equipment, and mass‑storage devices. The devices include on‑chip bootloaders for fast firmware download and support both device and host roles via USB On‑The‑Go.
The document also lists software libraries, development kits, and programming tools (FLIP, AVRISP, JTAGICE) that help developers implement HID, mass‑storage, and communication device classes without writing custom drivers.
