1.13 Brownout Detection
(Ask a Question)The PolarFire SoC FPGA functionality is guaranteed only if VDD is above the recommended level specified in the Datasheet. Brownout occurs when VDD drops below the minimum recommended operating voltage. When this occurs, the device operation may not be reliable. The design might continue to malfunction even after the supply is brought back to the recommended values because parts of the device might have lost functionality during brownout.
Important: For brownout detection on any PolarFire supply
(including VDD, VDD18, and VDD25), use external brownout detection circuits.
