AVR32 UC3A Processor Family

Flash MCU with Extensive Communication Capabilities

The UC3A Series offers modern communication interfaces like the 10/100-Mbps IEEE 802.3-compliant Ethernet MAC and full-speed USB 2.0 with on-the-go capability.

Designing TCP/IP aware applications that integrate well in a PC environment becomes very easy. An additional SRAM/SDRAM external bus interface allows expansion by adding more memory or by interfacing with other peripherals such as LCD controllers, FPGA and any other memory mapped device. The high performance AVR32 UC core, the memory system and on-chip peripherals are all connected to a 6-layer high speed system bus operating at 66 MHz and allow concurrent DMA transfer to each bus up to 264 MByte/s.

The excellent performance over operating frequency ratio allows to deliver 80 DMIPS at 66 MHz.
This is achieved with only 40 mA at 3.3V.

The UC3A family could be divide into three sub-families

UC3A0 - Family with Ethernet , EBI and USB-OTG

UC3A1 - Family with Ethernet and USB-OTG

UC3A3 - Family with EBI and high-speed USB-OTG
