The AVR XMEGA E5 devices provide the following features: in-system programmable flash with read-while-write capabilities; internal EEPROM and SRAM; four-channel enhanced DMA (EDMA) controller; eight-channel event system with asynchronous event support; programmable multilevel interrupt controller; 26 general purpose I/O lines; CRC-16 (CRC-CCITT) and CRC-32 (IEEE 802.3) generators; one XMEGA Custom Logic module with timer, counter and logic functions (XCL); 16-bit real-time counter (RTC) with digital correction; three flexible, 16-bit timer/counters with compare and PWM channels; two USARTs; one two-wire serial interface (TWI) allowing simultaneous master and slave; one serial peripheral interface (SPI); one sixteen-channel, 12-bit ADC with programmable gain, offset and gain correction, averaging, over-sampling and decimation; one 2-channel 12-bit DAC; two analog comparators (ACs) with window mode and current sources; programmable watchdog timer with separate internal oscillator; accurate internal oscillators with PLL and prescaler; and programmable brown-out detection.

The AVR XMEGA E5 devices have five software selectable power saving modes. The idle mode stops the CPU while allowing the SRAM, EDMA controller, event system, interrupt controller, and all peripherals to continue functioning. The power-down mode saves the SRAM and register contents, but stops the oscillators, disabling all other functions until the next TWI, or pin-change interrupt, or reset. In power-save mode, the asynchronous real-time counter continues to run, allowing the application to maintain a timer base while the rest of the device is sleeping. In standby mode, the external crystal oscillator keeps running while the rest of the device is sleeping. This allows very fast startup from the external crystal, combined with low power consumption. In extended standby mode, both the main oscillator and the asynchronous timer continue to run. In each power save, standby or extended standby mode, the low power mode of the internal 8MHz oscillator allows very fast startup time combined with very low power consumption.

All Atmel AVR XMEGA devices are supported with a full suite of program and system development tools, including C compilers, macro assemblers, program debugger/simulators, programmers, and evaluation kits.
