AT32UC3C164C-AUT

The AT32UC3C164C-AUT is a 32-bit AVR Flash Microcontroller featuring 64kB flash, 16kB SRAM. The device family features a floating point unit, flashVault code protection, single or dual CAN interfaces, dual LIN interfaces, USB with OTG, PWM with dead-time insertion, a 16-channel 12-bit ADC with dual sample-and-hold circuit for simultaneous sampling of 2 signals, a 2-channel 1.5Msps 12-bit analogue DAC. Designed with the multi-layered databus, 16KBs on-chip SRAM with dual interfaces, the AT32UC3C offers an outstanding data throughput. The AT32UC3C event system provides a connection between on-chip peripherals to off-load the CPU, saves power consumption and provides a 100% deterministic response to external and internal events. The processor implements a Memory Protection Unit (MPU) and a fast and flexible interrupt controller for supporting modern operating systems and real-time operating systems.
