Notes:
1. Values specified for power on current parameters are Commercial Grade. For Industrial Grade values, multiply Commercial Grade
values by 1.25.
2. ICCOMIN values listed here apply to the entire device (all banks).
General Power Supply Requirements
Proper decoupling of all FPGA power supplies is sessential.
