ATXMEGA128A4U-MH

The ATXMEGA128A4U-MH is a 16-bit low power AVR Microcontroller Unit featuring 128kB self-programming flash program memory, 4kB boot code section, 8kB SRAM, 2048-byte EEPROM, external bus interface, 4-channel DMA controller, 8-channel event system and up to 32MIPS throughput at 32MHz. The AVR CPU combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs many times faster than conventional single-accumulator or CISC based microcontrollers.
