The AVR UC3 L Series is Atmel’s first picoPower® 32-bit microcontroller, and offers a wide range of innovative technical features. The series is ideal for battery-powered, portable consumer applications, board controller, game pads, remote controls, and human interface devices. |
The AVR UC3 L Series runs on 165 µA/MHz in active mode, 600 nA with RTC running, and down to 9 nA with all clocks stopped. The UC3L features a built-in capacitive touch module supporting 17 channels in hardware, and each channel can be configured as buttons, sliders and wheels. The glue logic controller contains programmable logic and lookup tables that can be connected to GPIO pins, which can reduce the amount of external components. To safeguard sensitive data, FlashVault™ code protection enables on-chip flash to be partially programmed and locked, for secure on-chip storage of software intellectual property. 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.
