ATXMEGA32C4-AU Description

Short technical summary and product information.

The ATXMEGA32C4-AU 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 with a separate 4KB boot section, 4KB internal SRAM, and 1KB EEPROM. The device operates at up to 32 MHz and supports a supply voltage range of 1.6V to 3.6V.

 

Peripheral features include a four-channel event system, four 16-bit timer/counters, a 16-channel 12-bit ADC with 300 ksps sampling rate, two analog comparators, and a USB 2.0 full-speed device interface. Connectivity options include three USARTs (one with IrDA), two SPI interfaces, and two I2C-compatible two-wire interfaces. The microcontroller also includes a programmable watchdog timer, brown-out detection, and five sleep modes for power optimization.

 

The ATXMEGA32C4-AU is housed in a 44-lead TQFP package (10x10 mm) with 34 programmable I/O pins, suitable for surface-mount assembly. It is rated for an operating temperature range of -40°C to 85°C and is RoHS3 compliant. This microcontroller is ideal for applications requiring a balance of processing power, analog integration, and USB connectivity.
