Real-time Performance, High Integration and Ultra-low Power
Atmel® AVR® XMEGA® microcontrollers deliver the best possible combination of real-time performance, high integration and low power consumption for 8/16-bit MCU applications.
For an extra robust level of security against hackers for your intellectual properties (IPs), consider implementing our CryptoAuthentication™ device into your designs.
Key Features
-
High-precision analog — 12-bit analog-to-digital converters (ADCs) with gain stage and combined throughput of 4MSPS. Fast 12-bit digital-to-analog converters (DACs) with high drive strength, as well as other functions that reduce the need for external components.
-
Real-time performance — The Event System facilitates inter-peripheral signaling with 100% predictable response time. To offload the CPU, all peripherals can use direct memory access (DMA) for data transfer.
-
Atmel picoPower® technology — True 1.6V operation, and down to 100nA RTC operation with full SRAM retention for fastest possible wake-up time.
-
High integration — AVR XMEGA devices integrate Advanced Encryption Standard (AES) and Data Encryption Standard (DES) crypto modules, up to 32 pulse-width modulation (PWM) outputs, 8 UARTs, 4 TWI (I2C) and 4 serial peripheral interface (SPI) channels, a cyclic redundancy check (CRC) generator module and more.
-
AVR Software Library — A complete library of device drivers and communication stacks save time and development effort so you can focus on more important design tasks.
-
Atmel QTouch® Sensing — QTouch Library support enables you to easily realize robust capacitive touch sensing interfaces for buttons, sliders and wheels.
-
USB connectivity — Delivers full-speed operation without the need for external crystals, 31 endpoints, and a special multi-packet function that maximizes data transfer rates while minimizing CPU load.
-
XMEGA Custom Logic (XCL) — The AVR XMEGA E devices feature an innovative XMEGA Custom Logic module (XCL) consisting of two independent 8-bit timers/counters and two lookup tables used for defining glue logic. It is designed to reduce bill of material (BOM) and PCB size as the XCL can replace external circuitry such as delay elements, RS-latches, D-latches, D-flip-flops chip-select logic, AND, NAND, OR, NOR, XOR, XNOR, NOT, MUX AND/OR/XOR logic gates. In addition, it can, together with the USART, enable customized communication protocols.
