ATXMEGA32D3-AUR

The ATXMEGA32D3-AUR is a high-performance, low-power 8/16-bit AVR XMEGA microcontroller from Microchip Technology. It features 32KB of in-system self-programmable flash memory, 4KB SRAM, and 1KB EEPROM, with a maximum operating frequency of 32MHz (requires 2.7V minimum supply). The device includes a rich set of peripherals: a four-channel event system, five 16-bit timer/counters with PWM and advanced waveform extension, three USARTs (one with IrDA support), two two-wire interfaces (I2C/SMBus), two SPI modules, and a 16-channel 12-bit ADC (300ksps). It also features a CRC generator, 16-bit real-time counter, two analog comparators, and support for capacitive touch sensing via Atmel QTouch library.

Communication interfaces include I²C, IrDA, SPI, and UART/USART, while peripheral support includes brown-out detection, power-on reset, PWM, and watchdog timer. The microcontroller operates over a supply voltage range of 1.6V to 3.6V and an industrial temperature range of -40°C to 85°C. It is available in a 64-lead TQFP package (14x14mm) with 50 general-purpose I/O pins, suited for surface-mount assembly.

This microcontroller is ideal for embedded applications requiring a balance of processing power, low power consumption, and peripheral integration. It supports five sleep modes and a programmable multilevel interrupt controller, making it suitable for battery-powered and real-time control systems.
