operating voltage specs

Question asked by vsk on Feb 24, 2012

hello, I am planning to use ADSP-BF548 chip for the new design. As per the data sheet specs, the VDDEXT limits are 2.5/3.3V. But, 5V is applied to the ADSP-BF548BCCZ-5A chip on the adsp bf548 ezkit board. same is the case with VDDINT, VDDDDR supplies also. voltages actually applied to the chip are different from the datasheet specifications. why is it so? pl clarify.
