ATXMEGA128D3-AU Datasheet PDF - ATMEL

The ATXMEGA128D3-AU is a 8-bit high-performance low-power AVR XMEGA Microcontroller combines 128kB ISP flash memory (8kB boot code section) with read-while-write capabilities, 2kB EEPROM, 8kB SRAM, a four-channel event system, a programmable multi-level interrupt controller, 50 general purpose I/O lines, a 16-bit real time counter, five flexible 16-bit timer/counters with compare modes and PWM, three USARTs, two 2-wire interfaces, two serial peripheral interfaces, one 16-channel/12-bit A/D converter with optional differential input with programmable gain, two analogue comparators with window mode, a programmable watchdog timer with separate internal oscillator, accurate internal oscillators with PLL and prescaler and a programmable brown-out detection. The Program and Debug Interface (PDI), a fast 2-pin interface for programming and debugging, is available.
