7.3.3.1. Power Up

Power up all the power supplies that are monitored by the POR circuitry. All power supplies, including VCCPGM , must ramp up from 0 V to the recommended operating voltage level within the ramp-up time specification. Otherwise, hold the nCONFIG pin low until all the power supplies reach the recommended voltage level.

VCCPGM Pin

The configuration input buffers do not have to share power lines with the regular I/O buffers in Intel® Cyclone® 10 GX devices. Connect VCCPGM to 1.8 V.

The operating voltage for the configuration input pin is independent of the I/O banks power supply, VCCIO , during configuration. Therefore, Intel® Cyclone® 10 GX devices do not require configuration voltage constraints on VCCIO .

Intel recommends connecting the I/O banks power supply, VCCIO , of the dual-purpose configuration pins for FPP x8, x16, and x32 to VCCPGM .
