The Microchip Technology ATXMEGA256A3B-AU is an 8/16-bit AVR XMEGA microcontroller designed for low-power and high-performance embedded applications. It features 256KB of in-system self-programmable Flash, 16KB internal SRAM, and 4KB EEPROM. The core operates at up to 12 MHz from 1.6V to 3.6V and up to 32 MHz from 2.7V to 3.6V.
Peripheral features include four DMA channels, an eight-channel event system, seven 16-bit timer/counters, six USARTs, two I2C interfaces, two SPI peripherals, an AES and DES crypto engine, a 32-bit real-time counter with battery backup, 16-channel 12-bit ADC, 2-channel 12-bit DAC, and four analog comparators. The device is housed in a 64-lead TQFP (14x14 mm) package and supports surface mount mounting. Operating temperature range is -40°C to 85°C. Typical applications include industrial control, climate control, hand-held battery devices, and factory automation.
