ATXMEGA32A4U-MHR Description

Short technical summary and product information.

The ATXMEGA32A4U-MHR is a low-power, high-performance 8/16-bit microcontroller from Microchip Technology's AVR XMEGA family. It features a 32KB self-programmable flash memory, 4KB SRAM, and 1KB EEPROM, providing ample storage for code and data.

 

Operating at up to 32 MHz with a supply voltage range of 1.6V to 3.6V, this MCU offers a rich set of peripherals including a 12-bit ADC with 12 channels (2 Msps), a 12-bit DAC (2 channels, 1 Msps), five 16-bit timer/counters, and a four-channel DMA controller for efficient data transfers. It also integrates a USB 2.0 Full Speed device interface, along with I²C, SPI, UART/USART, and IrDA connectivity.

 

Designed for demanding embedded applications, the device includes an eight-channel event system, AES and DES crypto engine, and CRC generator for data integrity. It is housed in a compact 44-VFQFN exposed pad package (7x7 mm) suitable for surface-mount assembly and operates over an industrial temperature range of -40°C to 85°C.
