Nor Flash

After power up, I need to wait 25mS in order to read data from the Flash correctly.   Anything less then 25mS and I get data errors.

Is the datasheet correct is specifying 35uS for rising edge of Vcc/Vccio to rising edge of RESET#?

Thanks,

Tim

Hello,

Thank you for contacting Cypress Technical Support, an Infineon Technologies. 

 It should be as in the datasheet. You maybe having your Vcc ramp very slow, but when it gets to 2.7V it should be 35uS.

Thank you
