32-bit AVR UC3
A0/A1 Series
Designed for high data throughput, low power consumption and outstanding computing performance, the A0 and A1 Series features high connectivity with USB On-The-Go, Ethernet MAC and SDRAM interfaces. These features, combined with a fast flash and large internal SRAM, make ideally suited for data-intensive applications.
The A0 and A1 Series are particularly well suited for applications requiring Ethernet or USB connectivity and high computing performance. These devices are used in a wide range of applications including audio, biometric, communication, industrial control and web servers.
A3/A4 Series
The AVR UC3 A3 Series is designed for exceptionally high data throughput with Hi-Speed USB On-The-Go, SD/SDIO card, Multi-Level-Cell (MLC) NAND flash with ECC and SDRAM interfaces. With its multi-layered AVR databus, 128 KB on-chip SRAM with triple high-speed interfaces, and multi-channel peripheral and memory-to-memory DMA controller, the AT32UC3A3 offers outstanding data throughput. The device also features a Hi-Fi stereo Audio DAC and a full duplex multi-channel I2S audio interface.
The AT32UC3A3 series is available with an optional AES crypto module capable of 128 to 256-bit AES encryption at speeds of up to 22.8 MBytes/s. Note that export restrictions apply to this device variant.
The A3 Series is particularly well suited for applications requiring Hi-speed USB connectivity, high computing performance and fast memory interfaces. These devices are used in a wide range of applications including audio, biometric, communication, USB to SDcard bridges and USB dongles.
B Series
The AVR UC3 B Series is designed for high data throughput, low power consumption and outstanding computing performance. The series features high connectivity with USB On-The-Go. This feature, combined with a fast flash and large internal SRAM, make it ideally suited for data-intensive applications.
The B series is particularly well suited for applications requiring high computing performance and low power consumption in combination with USB connectivity. These devices are used in a range of applications, including USB Human Interface devices, USB stick gateway, biometric, bridging, industrial control, and low-power portable applications.
L Series
The AVR UC3 L Series is Atmel’s first picoPower 32-bit microcontroller. 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 technological 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 UC3L series is targeted at portable consumer applications, board controller, game pads, remote controls, and human interface devices.
