A3/A4-Series AT32UC3 AVR 32-Bit MCUs

Microchip Technology A3/A4-Series AT32UC3 AVR 32-Bit MCUs are designed for exceptionally high data throughput with Hi-Speed USB device and host, SD/SDIO card, Multi-Level-Cell (MLC) NAND flash with ECC and SDRAM interfaces. It is particularly well suited for applications like audio, biometrics, communication, USB to SD card bridges, and USB dongles. With its multi-layered AVR® databus, 128 KB on-chip SRAM split into three banks for higher throughput and multi-channel peripheral and memory-to-memory DMA controller, the A3/A4 offers outstanding data transfer rates. The device also features a 16-bit stereo Audio DAC and an entire duplex multi-channel I2S audio interface. The A3/A4 series has an optional AES crypto module capable of 128- to 256-bit AES encryption at speeds of up to 22.8MB/s.
