If a limit exists, this specification is based on characterization.
The mask revision code appears on the device top marking. See
The ramp time is measured from 10% to 90% of the full nominal voltage swing for all I/O standards.
For information on power-on current needs, see
Mask revision, fabrication, and process codes appear
screened. Devices ordered with SCD0974 or with ‘GQ’ fabrication/process code are also described in XCN05009.
To specifically order mask revision ’E’ devices, append “0974” to the standard part number. For example, “XC3S50-4VQ100C”
becomes “XC3S50-4VQ100C0974”. Mask revision ‘E’ devices are
