64-Kbyte self-programming Flash Program Memory, 8-Kbyte SRAM, 4-Kbyte EEPROM, 8 Channel 10-bit A/D-converter. JTAG interface for on-chip-debug. Up to 16 MIPS throughput at 16 MHz. 2.7 - 5.5 Volt operation.
The ATmega32U6/AT90USB64/128 is a low-power CMOS 8-bit microcontroller based on the
AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, theATmega32U6/AT90USB64/128 achieves throughputs approaching 1 MIPS per MHz allowing
the system designer to optimize power consumption versus processing speed.
