描述 Description

The high-performance 32-bit AVR? UC3 RISC microcontroller is designed for cost-sensitive embedded 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.
