Enabling Standalone Operation

A key feature of our biomedical acquisition and processing platform is standalone operation: The system must be able to provide all required supply voltages and clock frequencies without external components. Furthermore, the three involved uControllers must load their program code from non-volatile storage. The commercial radio SoC has integrated flash memory for this purpose; our two own ASICs share the discrete multi-Gigabit NAND flash that is also used for data storage.
