Microchip (AT32UC3L0256-AUT) 32 Bit Microcontroller, High performance

32 Bit Microcontroller, High performance, Low Power, AT32 Family AT32UC3L Series Microcontrollers Product Overview The AT32UC3L0256-AUT is a 32-bit high-performance 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.
