Atmel AT32UC3 AVR 32-Bit MCUs
Atmel's AT32UC3 AVR® 32-Bit UC3 Microcontrollers
take 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 of the AT32UC3 AVR® 32-Bit UC3 Microcontrollers move performance and power consumption to the next step. Atmel's AT32UC3 AVR® 32-Bit UC3 Microcontrollers
peripheral DMA controller and multi-layer high-speed bus architecture
make them ideal for high throughput applications. Intelligent
peripherals and dynamic power control make the AT32UC3 AVR® 32-Bit UC3 Microcontrollers the obvious choice for portable and battery-powered applications.
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.
