The AVR UC3 C Series is designed for industrial and automotive
control applications, including high-speed communication and
motor control. The devices feature single or dual CAN interfaces,
a full speed USB with OTG, NAND flash and SDRAM interface,
PWM with dead-time insertion, two 1.5 MSPS 12-bit ADC with
16 channels and dual sample-and-hold circuitry for synchronized
sampling of 2 signals, two 1.5 12-bit analog DAC with dual
outputs. Designed with the multi-layered AVR32 databus, 68
KB on-chip SRAM with triple high-speed interfaces, and multi-
channel Peripheral and memory to memory DMA controller, the
AT32UC3C offers outstanding data throughput.
The AT32UC3C Peripheral Event System provides a connection

most cost-sensitive embedded applications that require USB
device connectivity. Designed to be 100% pin and functionally
compatible with the UC3B series, the UC3D offers a reduced
maximum speed, a USB device interface without OTG function,
and I/O pads limited to 3.6V maximum voltage.

The AVR UC3 L Series is Atmel’s first picoPower 32-bit microcon-
troller. It delivers down to 0.48 mW/MHz in active operation and
sleep mode consumption of 1.5uA with RTC running, or 100nA with
all clocks stopped. The L series delivers a wide range of techno-
logical innovations to the 32-bit microcontroller market. It is the
industry’s first 32-bit microcontroller with a built-in Capacitive Touch
Peripheral. The new FlashVault? code protection allows the on-chip
flash to be partially programmed and locked, creating secure on-
chip storage for software intellectual property. Code stored in the
FlashVault will execute as normal, but it cannot be read, copied or

debugged. The FlashVault code protection can carry software such as a math library or an encryption
algorithm to potentially untrustworthy environments where the rest of the source code can be developed
and debugged.
Other innovations first introduced in the UC3L Series include SleepWalking? intelligent peripherals, a
Peripheral Event System, Clock Failure Protection, Spread Spectrum Clocks with fast startup times, a
Frequency Meter, an RTC with Crystal Precision Tuner and calendar mode, and a PWM output on all 36
I/O pins.
The L series is targeted at portable consumer applications, board controller, game pads, remote con-
trols, and human interface devices.
