1. Description
32099AS–AVR32–06/09
The AT32UC3L is a complete System-On-Chip microcontroller based on the AVR32 UC RISC
processor running at frequencies up to 50MHz. 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 AT32UC3L embeds state-of-the-art picoPower technology for ultra-low power consumption.
Combined power control techniques are used to bring active power as low as 0.5mW/MHz, and
leakage down to 100nA while still retaining a bank of backup registers. The device allows a wide
range of trade-offs between functionality and power consumption, giving the user the ability to
reach the lowest possible power consumption with the feature set required for the application.
The Peripheral Direct Memory Access (DMA) controller enables data transfers between periph-
erals and memories without processor involvement. The Peripheral DMA controller drastically
reduces processing overhead when transferring continuous and large data streams.
The AT32UC3L incorporates on-chip Flash and SRAM memories for secure and fast access.
The FlashVault technology allows secure libraries to be programmed into the device. The secure
libraries can be executed while the CPU is in Secure State, but not read by non-secure software
in the device. The device can thus be shipped to end costumers, who will be able to program
their own code into the device, accessing the secure libraries, but without risk of compromising
the proprietary secure code.
The Peripheral Event System allows peripherals to receive, react to, and send peripheral events
without CPU intervention. Asynchronous interrupts allow advanced peripheral operation in low
power sleep modes.
The Power Manager improves design flexibility and security. The Power Manager supports
SleepWalking functionality, by which a module can be selectively activated based on peripheral
events, even in sleep modes where the module clock is stopped. Power monitoring is supported
by on-chip Power-On Reset (POR), Brown-Out Detector (BOD), and Supply Monitor (SM). The
device features several oscillators, such as Digital Frequency Locked Loop (DFLL), Oscillator 0
(OSC0), and system RC oscillator (RCSYS). Either of these oscillators can be used as source
for the system clock. The DFLL is a programmable internal oscillator from 20 to 150MHz. It can
be tuned to a high accuracy if an accurate oscillator is running, e.g. the 32KHz crystal oscillator.
The Watchdog Timer (WDT) will reset the device unless it is periodically serviced by the soft-
ware. This allows the device to recover from a condition that has caused the system to be
unstable.
The Asynchronous Timer (AST) combined with the 32KHz crystal oscillator supports powerful
real-time clock capabilities, with a maximum timeout of up to 136 years. The AST can operate in
counter mode or calendar mode.
The Frequency Meter (FREQM) allows accurate measuring of a clock frequency by comparing it
to a known reference clock.
The device includes six identical 16-bit Timer/Counter (TC) channels. Each channel can be inde-
pendently programmed to perform frequency measurement, event counting, interval
measurement, pulse generation, delay timing, and pulse width modulation.
