B-Series AT32UC3 AVR 32-Bit MCUs

Microchip Technology B-Series AT32UC3 AVR 32-Bit MCUs are designed for high data throughput and outstanding computing performance in space-constrained applications. It is especially well-suited for applications like USB Human Interface devices, USB stick gateway, biometrics, bridging, industrial control, and low-power portable applications. The series features high connectivity with a USB device and host. This feature, combined with a fast flash and large internal SRAM, makes it a perfect fit for data-intensive applications.
