AT40KAL Series FPGA
Atmel FPGAs require a minimum rated power supply current capacity to insure proper
initialization, and the power supply ramp-up time does affect the current required. A fast
ramp-up time requires more current than a slow ramp-up time.

1. This specification applies to Commercial and Industrial grade products only.
2. Devices are guaranteed to initialize properly at 50% of the minimum current listed
3. Ramp-up time is measured from 0 V DC to 3.6 V DC. Peak current required lasts less
above. A larger capacity power supply may result in a larger initialization current.
