ATXMEGA256A3U-AU

The ATXMEGA256A3U-AU is a high performance, low power 8/16bit AVR XMEGA A3U microcontroller in 64 pin TQFP package. This device achieves throughputs approaching 1MIPS per MHz by executing powerful instructions in a single clock cycle. This allows system designer to optimize power consumption versus processing speed. The device has seven 16bit timer/counters, 16bit real time counter (RTC) with separate oscillator, two sixteen channel, 12bit ADC, one two channel, 12bit DAC, four analogue comparators and programmable watchdog timer with separate on-chip ultra low power oscillator.

• Maximum operating frequency of 32MHz
• 256KB of in-system self programmable flash
• 4KB EEPROM and 16KB internal SRAM memory
• Operating voltage range from 1.6V to 3.6V
• 50 programmable I/O pins
• JTAG (IEEE 1149.1 compliant) and PDI (program and debug) interfaces
• QTouch library support
• 16bit real time counter (RTC) with separate oscillator
• USB 2.0, seven USART, two I2C and SMBus interfaces
• Operating temperature range from -40°C to 85°C
