Hi,

 

     I am using +2.5V for powering VDDIO pins of ADSP-TS201S. I have selected to use a +3.3V Flash as boot FLASH for this. I understand that the pins of DSP will withstand +3.3V but the VOH(min) of the DSP is where +2.18V as the VIH(min) of most of the FLASH ICs available is +2.31V. Kindly advise regarding the selection of FLASH memory for this application.

 

Thanks in advance.
