This document is about a high-performance, low-power AVR® 8-bit microcontroller. It features an advanced RISC architecture with powerful instructions, single clock cycle execution, general-purpose working registers, and fully static operation. It has non-volatile program and data memories, with options for in-system self-programmable flash and independent lock bits for boot code section. It supports true read-while-write operation, EEPROM and SRAM memories, JTAG interface, and USB 2.0 full-speed/low-speed device and On-The-Go module with high data transfer rates.
