The AT32UC3L016-AUT is a high-performance 32-bit AVR UC3 RISC Microcontroller is designed for applications that require low power consumption, high code density and high performance. The microcontroller's memory protection unit (MPU) and fast, flexible interrupt controller support the latest real-time operating systems. The secure access unit (SAU) with MPU provide enhanced security and integrity. A rich set of DSP instructions delivers higher computational capability. The microcontroller embeds state-of-the-art picoPower? technology for ultra-low power consumption. A combination of power control techniques brings active current consumption down to 165μA/MHz and leakage down to 9nA while still retaining a bank of backup registers. The device offers a wide range of trade-offs between functionality and power consumption to reach the lowest possible power usage for the application's required feature set.
