The ATXMEGA32A4-AU from Microchip is an AVR XMEGA MCU with 32KB Flash, 4KB SRAM, 1KB EEPROM, 12-bit ADC/DAC, and event system in TQFP-44 for mixed-signal applications.

The ATXMEGA32A4-AU is an 8/16-bit AVR XMEGA microcontroller from Microchip in TQFP-44, running at 32MHz with 32KB Flash and 2KB SRAM. The XMEGA architecture extends the classic AVR with a more modular peripheral system and DMA controller. The Event System is a key XMEGA feature: 8 event channels allow peripherals to trigger actions in other peripherals without CPU intervention. For example, a timer overflow can trigger an ADC conversion, which triggers a DMA transfer to SRAM, all autonomously. The 12-bit ADC (ADC0/ADC1) supports up to 1Msps with hardware oversampling (up to 16x for effective 13-bit resolution). Four DAC channels (2 x 12-bit on DAC0/DAC1) provide analog output capability rare in 8-bit MCUs. Four USARTs support UART, SPI (master mode), and LIN protocols. Two TWI (I2C) interfaces operate as master or slave at up to 400kHz. The Crypto module provides AES-128/256 and DES encryption/decryption in hardware (8 clock cycles for AES-128). The PDI (Program and Debug Interface) replaces the classic ISP interface, providing faster programming (up to 2MHz clock). The 32kHz crystal oscillator on TOSC1/TOSC2 (PR0/PR1 pins) provides accurate RTC timing. The device includes a calibration row with oscillator calibration values for 2MHz and 32MHz internal RC oscillators. The -AU suffix specifies TQFP-44, industrial temperature (-40C to +85C).
