ATMEL 32-bit AVR UC3 Microcontrollers

The World's Most-Efficient 32-Bit Microcontroller

The 32-bit AVR® UC3 microcontroller takes efficiency to a new level, going beyond high performance and low power consumption. Native fixed point DSP support, dual port SRAM, multi layer data bus, peripheral DMA controller, peripheral event system and intelligent peripherals move performance and power consumption to the next step.

The peripheral DMA controller and multi-layer high-speed bus architecture make the UC3 microcontrollers ideal for high-throughput applications. Intelligent peripherals and dynamic power control make UC3 devices the obvious choice for portable and battery-powered applications. Selected UC3 devices include an integrated floating-point unit (FPU) which improves arithmetic performance on decimal numbers, with better precision and wider dynamic range. For sensor fusion processing applications, UC3L devices can work with your own sensor fusion code and sensors provided by our extensive range of partners. Combine your UC3 designs with our CryptoAuthentication™ devices for an added level of security against hackers and cloners.

Key Features

• Connectivity — USB device and host, Ethernet MAC, SDRAM, NAND flash, and fast serial interfaces are ideal for complex applications.
• Arithmetic performance — Integrated FPU increases precision and dynamic range in digital signal processing.
• High data throughput — Peripheral DMA, multi-layered databus and large on-chip SRAM remove bottlenecks in high-speed communication.
• Low power consumption — picoPower® technology delivers the industry's lowest power consumption in active and sleep modes.
• Software Library — All UC3 devices are supported by AVR Software Framework, a complete library of device drivers and middleware.
