ATMEGA16U4-AU

The ATMEGA16U4-AU is a 8-bit low power high performance AVR RISC-based Microcontroller features16kB ISP flash memory, 8kB boot code section, 2.5kB SRAM, 1024B EEPROM, USB 2.0 full-speed/low speed device, high-speed PWMs, 12-channel 10-bit A/D-converter and JTAG interface for on-chip-debug. The device achieves up to 16 MIPS throughput at 16MHz, 2.7 to 5.5V operation. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, allowing you to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
