The Microchip Technology AT32UC3A3256-ALUR is a 32-bit RISC microcontroller featuring an AVR RISC CPU operating at up to 66MHz. This CMOS device offers 262144 bytes of FLASH program memory and 65536 bytes of data RAM. It includes a rich set of peripherals such as dual TWI, dual SPI, four USARTs, I2S, IRDA, LIN, SDMMC, and USB connectivity. The microcontroller is equipped with 12 DMA channels, 6 timers, a Watchdog Timer (WDT), Brown-Out Detection (BOD), and Power-On Reset (POR). For analog interfacing, it provides 8 channels of 10-bit ADCs and 2 channels of 16-bit DACs. The AT32UC3A3256-ALUR supports boundary scan and operates within an industrial temperature range of -40°C to +85°C. It is supplied in a 144-lead LFQFP package with a 0.50mm terminal pitch. This component is suitable for applications in industrial automation, consumer electronics, and automotive systems.
