ATXMEGA128D4-AU

The ATXMEGA128D4-AU is a 16-bit low-power AVR XMEGA Microcontroller Unit combines 128kB ISP flash memory (8kB boot code section) with read-while-write capabilities, 2kB EEPROM, 8kB SRAM, 4-channel event system, a programmable multi-level interrupt controller, 34 general purpose I/O lines, a 16-bit real time counter, 4 flexible 16-bit timer/counters with compare modes and PWM, two USARTs, two -Wire Interfaces (TWIs), two Serial Peripheral Interfaces (SPIs), one 12-channel/12-bit A/D converter with optional differential input with programmable gain, 2 analogue comparators with window mode, a programmable watchdog timer with separate internal oscillator, accurate internal oscillators with PLL and pre-scaler and programmable brown-out detection. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed.
