1.3 Limiting VDD Surge Current

(Ask a Question)

After device power-up, certain user-initiated functions can result in a surge current on VDD. This section describes how to minimize this surge current in SmartFusion2/IGLOO2 devices. Minimizing this surge current ensures that VDD voltage is maintained within the recommended operating range. This additional surge current does not occur during device power-up and has no effect on device reliability. If VDD voltage drops below the minimum recommended operating voltage, the FPGA may experience brownout. For more information about brownout and brownout prevention, see 1.12 Brownout Detection (BOD).
