11. Power-On Supply Requirements
7750A–AERO–07/07
Atmel FPGAs require a minimum rated power supply current capacity to ensure proper initializa-
tion. The power supply ramp-up time affects the current required. A fast ramp-up time requires
more current than a slow ramp-up time.
Moreover, the supply voltage must respect a sequence as described below:
The peripheral power up must be done before the core power up. No ramp up is required on
VCC power supply.
Table 11-1.

Maximum Current Supply
1. Devices are guaranteed to initialize properly at 50% of the minimum current listed above. A
2. 2. Ramp-up time is measured from 0V DC to 1.8V DC. Peak current required lasts less than 2
larger capacity power supply may result in a larger initialization current.
