PRODUCTION DATA
The RF Core contains an Arm Cortex-M0 processor that interfaces the analog RF and base-band circuits, handles data to and from the system side, and assembles the information bits in a given packet structure. The RF core offers a high level, command-based API to the main CPU.
The RF core is capable of autonomously handling the time-critical aspects of the radio protocols (Bluetooth low energy) thus offloading the main CPU and leaving more resources for the user application.
The RF core has a dedicated 4-KB SRAM block and runs initially from separate ROM memory. The Arm Cortex-M0 processor is not programmable by customers.
