The two Arm Cortex-M33 processors allow minimal porting efforts by sharing the power, clock, and peripheral architecture with the nRF51, nRF52, and nRF91 series of PAN/LAN SoCs. A full-featured Arm Cortex-M33 processor is the application core that includes DSP instructions, FPU, and running at up to 128MHz with 1MB of flash and 512kB of RAM. The CPU enables the application processor to run at 64MHz, increasing energy efficiency. The network core is an Arm Cortex-M33 processor with a reduced feature set, designed for ultra-low power operation. The processor runs at a fixed 64MHz frequency and contains 256kB of flash and 64kB of RAM.
The peripheral set offers a variety of analog and digital functionality permitting single-chip implementation of a wide range of applications.
