ATXMEGA32D4-AU Datasheet PDF - ATMEL

The ATXMEGA32D4-AU is a 8-bit high-performance low-power AVR XMEGA Microcontroller combines 32kB ISP flash memory (4kB boot code section) with read-while-write capabilities, 1kB EEPROM, 4kB SRAM, four-channel event system, a programmable multi-level interrupt controller, 34 general purpose I/O lines, a 16-bit real time counter, four flexible 16-bit timer/counters with compare modes and PWM, two USARTs, 2 Two-Wire Interfaces (TWIs), two Serial Peripheral Interfaces (SPIs), one 12-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 programmable brown-out detection. The Program and Debug Interface (PDI), a fast 2-pin interface for programming and debugging, is available.
