Notes to Table 2–3:
(1) PLL digital voltage is regulated from VCCA_FPLL
.
(2) If you do not use the design security feature in Cyclone V devices, connect VCCBAT to a 1.5-V, 2.5-V, or 3.0-V power supply. The power-on reset
(POR) circuitry monitors VCCBAT. Cyclone V devices do not exit POR if VCCBAT stays low.
Table 2–4 lists the transceiver power supply recommended operating conditions for
Cyclone V GX devices.

Table 2–5 lists the steady-state voltage values expected from Cyclone V
system-on-a-chip (SoC) FPGA with ARM®-based hard processor system (HPS). Power
supply ramps must all be strictly monotonic, without plateaus.
