6.2.1. Power-On Reset (POR) Circuit
The POR circuit keeps the device in reset state until the power supply voltage levels have stabilized during device power up.
- VCCINT and VCCA are monitored for brown-out conditions after device power up.
- VCCA is the analog power to the phase-locked loop (PLL).
In some applications, it is necessary for a device to wake up very quickly to begin operation. Intel® Cyclone® 10 LP devices offer the fast POR time option to support fast wake-up time applications. The fast POR time option has stricter power-up requirements compared to the standard POR time option. You can select either the fast or standard POR option with the MSEL pin settings.
