The ATXMEGA256A3U-AN is a member of the Atmel AVR XMEGA A3U family of low-power, high-performance 8/16-bit microcontrollers. It combines 256KB of in-system self-programmable flash memory, 16KB SRAM, and 4KB EEPROM, providing ample storage for complex applications.
Key features include operation from 1.6V to 3.6V, with a maximum clock frequency of 32MHz at 2.7V to 3.6V and 12MHz at lower voltages. The device integrates a USB 2.0 full-speed device interface, four DMA channels, an eight-channel event system, seven 16-bit timer/counters, a 16-channel 12-bit ADC with 2 MSPS sampling rate, a two-channel 12-bit DAC at 1 MSPS, and a hardware AES/DES crypto engine.
Peripheral interfaces include I2C, SPI, UART/USART, and IrDA support. It also features brown-out detection, power-on reset, PWM outputs, and a watchdog timer. With 50 general-purpose I/O pins, the microcontroller offers flexibility for a wide range of embedded designs.
The ATXMEGA256A3U-AN is available in a surface-mount 64-TQFP package (14x14mm) and is rated for an operating temperature range of -40°C to 105°C (TA). It is RoHS3 compliant and halogen-free, suitable for environmentally conscious designs.
