The ATXMEGA256A3B-MH is a high-performance, low-power 8/16-bit AVR XMEGA microcontroller from Microchip Technology. It features 256KB of in-system self-programmable flash memory, 16KB internal SRAM, and 4KB EEPROM. The device operates at up to 32 MHz at 2.7V-3.6V and 12 MHz at 1.6V-3.6V, with a supply voltage range of 1.6V to 3.6V.
Peripheral features include a four-channel DMA controller, an eight-channel event system, seven 16-bit timer/counters with output compare and input capture, six USARTs (one with IrDA), two I2C interfaces, two SPI peripherals, and a crypto engine supporting AES and DES. The microcontroller also integrates two 12-bit, 2 Msps ADCs with 16 channels, one 12-bit, 1 Msps DAC with 2 channels, and four analog comparators.
The device is housed in a 64-VFQFN exposed pad package (9x9mm) and supports surface-mount mounting. It is suitable for applications such as industrial control, climate control, hand-held battery-powered devices, and factory automation. The operating temperature range is -40°C to 85°C.
