AVR® 32-Bit UC3 Microcontrollers

Microchip 32-bit AVR® UC3 RISC Microcontrollers (MCUs)are designed for cost-sensitive embedded applications that require low power consumption, high code density, and high performance. The AVR UC3 MCUs feature a memory protection unit (MPU) and fast, flexible interrupt controller, supporting 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.
