| The CPU is an ARM Cortex-M0+ (double core) running up to 133 MHz (scalable). It supports DMA. There is no FPU, however. A Nested Vector Interrupt Controller is also present, along with a 24-bit timer. CPU and NIC can be put into the very low power mode. | The CPU is an ARM Cortex-M0+ (double core) running up to 133 MHz (scalable). It supports DMA. There is no FPU, however.
