1. Description
32059K–03/2011
The AT32UC3B is a complete System-On-Chip microcontroller based on the AVR32 UC RISC
processor running at frequencies up to 60 MHz. AVR32 UC is a high-performance 32-bit RISC
microprocessor core, designed for cost-sensitive embedded applications, with particular empha-
sis on low power consumption, high code density and high performance.
The processor implements a Memory Protection Unit (MPU) and a fast and flexible interrupt con-
troller for supporting modern operating systems and real-time operating systems.
Higher computation capability is achieved using a rich set of DSP instructions.
The AT32UC3B incorporates on-chip Flash and SRAM memories for secure and fast access.
The Peripheral Direct Memory Access controller enables data transfers between peripherals and
memories without processor involvement. PDCA drastically reduces processing overhead when
transferring continuous and large data streams between modules within the MCU.
The Power Manager improves design flexibility and security: the on-chip Brown-Out Detector
monitors the power supply, the CPU runs from the on-chip RC oscillator or from one of external
oscillator sources, a Real-Time Clock and its associated timer keeps track of the time.
The Timer/Counter includes three identical 16-bit timer/counter channels. Each channel can be
independently programmed to perform frequency measurement, event counting, interval mea-
surement, pulse generation, delay timing and pulse width modulation.
The PWM modules provides seven independent channels with many configuration options
including polarity, edge alignment and waveform non overlap control. One PWM channel can
trigger ADC conversions for more accurate close loop control implementations.
The AT32UC3B also features many communication interfaces for communication intensive
applications. In addition to standard serial interfaces like USART, SPI or TWI, other interfaces
like flexible Synchronous Serial Controller and USB are available. The USART supports different
communication modes, like SPI mode.
The Synchronous Serial Controller provides easy access to serial communication protocols and
audio standards like I
The Full-Speed USB 2.0 Device interface supports several USB Classes at the same time
thanks to the rich End-Point configuration. The Embedded Host interface allows device like a
USB Flash disk or a USB printer to be directly connected to the processor.
Atmel offers the QTouch library for embedding capacitive touch buttons, sliders, and wheels
functionality into AVR microcontrollers. The patented charge-transfer signal acquisition offers
robust sensing and included fully debounced reporting of touch keys and includes Adjacent Key
Suppression
QTouch Suite toolchain allows you to explore, develop, and debug your own touch applications.
AT32UC3B integrates a class 2+ Nexus 2.0 On-Chip Debug (OCD) System, with non-intrusive
real-time trace, full-speed read/write memory access in addition to basic runtime control. The
Nanotrace interface enables trace feature for JTAG-based debuggers.
