AVR32 UC3 32-BIT FLASH MICROCONTROLLER
High computational throughput
The AVR32 UC core single cycle operation and
its tightly coupled SRAM allow high speed data
transfers and fast computation without latencies
from pipeline stalls or system bus arbitrations.
Deterministic & real-time control
Specific instructions for atomic read-modify-write
(bit banging) and fast interrupt response give
precise control of outgoing and incoming external
events and allow for fast operating system context
switching.
Low power
The AVR32 UC core works smarter. It requires
lower bus activity and lower operating frequency
than other architectures hence providing the best
power to performance ratio.
Key Benefits
AVR32 UC Core
The AVR32 UC core is the first 32-bit core in the industry to integrate single-cycle read/
write SRAM with a direct interface to the pipeline that bypasses the system bus to achieve
faster execution, better deterministic behaviour and lower power consumption. The core
can deliver up to 1.3 Dhrystone MIPS/MHz, running from on-chip Flash memory.
The AVR32 UC core is based on a 3-stage pipeline Harvard architecture and includes
advanced features such as DSP arithmetics, single-cycle multiply and accumulate
instructions and atomic bit or word read-modify-write instructions.
Low system cost
The AVR32 instruction set architecture is optimized
for C/C++ languages and gives high code density
using less memory.
High reliability
The AVR32 UC3 safely boots from the RC-
oscillator. The brown-out detector and the
hardware watchdog protect the system from
environment defects. The Non-Maskable Interrupt
ensures critical event processing.
The MPU and privilege & unprivileged operating
modes keep kernel and application levels separate.
Easy to use
High performance and code density allows
software designers to use high level programming
methodologies without execution speed or cost
penalty. The high featured on-chip emulation
system gives better code insights, and shortens
debugging time.

AVR32 UC3A SeriesFlash MCU with Extensive Communication Capabilities
www.atmel.com
The UC3A Series offers communication interfaces such as 10/100-Mbps IEEE 802.3
compliant Ethernet MAC (optional) and USB 2.0 full-speed with On-The-Go capability.
Designing TCP/IP 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 devices.
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 allows
concurrent DMA transfers on each bus up to 264 MByte/s.
The excellent ratio of performance versus operating frequency ratio delivers 80 DMIPS
at 66 MHz. This is achieved with only 40 mA at 3.3V.
AVR32 UC3B SeriesLow-Power Flash MCU with USB On-The-Go
The AVR32 UC3B is idealy suited for applications requiring a high performance Flash MCU
where space and/or power consumption is of concern. The AVR32 UC3B Series delivers
72 DMIPS at 60 MHz and only consumes 23 mA at 3.3V.
The integrated full-speed USB 2.0 interface with On-The-Go capabilities provides an easy
way to interface with off-the-shelf USB devices or with other embedded applications
already designed to offer USB.
The advanced DSP capabilities and the USB interfaces also makes the UC3B series ideal
as an MCU host companion to extend existing systems, with an interface to real-time
sensors/actuators and to open up applications to USB device and host capabilities.
