Spartan-6 Configuration - Can 1.8V be used on VCCO_2 (VCCO for I/O bank 2) during configuration for Spartan-6 devices?

Description

Can 1.8V be used on VCCO_2 (VCCO for I/O bank 2) during configuration for Spartan-6 devices?

Solution

For Spartan-6 devices, VCCO_2 can be powered by 1.8V supply during (and after) configuration. However, Note 4 for Table 2 in the Spartan-6 FPGA Data Sheet: DC and Switching Characteristics states: "4. During configuration, if VCCO_2 is 1.8V, then VCCAUX must be 2.5V." It is very important that this data sheet requirement is adhered to, otherwise there is a possibility that the configuration process could be prone to failure.
