For More Information
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
There is no change to this data sheet as a result of offering the device as an Eon product. Any
changes that have been made are the result of normal data sheet improvement and are noted in
the document revision summary, where supported. Future routine revisions will occur when
appropriate, and changes will be noted in a revision summary.
Eon continues to support existing part numbers beginning with “Eon” and “cFeon” top marking. To
order these products, during the transition please specify “Eon top marking” or “cFeon top marking”
on your purchasing orders.
Please contact your local sales office for additional information about Eon memory solutions.
Eon Silicon Solution Inc. (hereinafter called “Eon”) is going to provide its products’ top marking on
ICs with < cFeon > from January 1st, 2009, and without any change of the part number and the
compositions of the ICs. Eon is still keeping the promise of quality for all the products with the
same as that of Eon delivered before. Please be advised with the change and appreciate your
kindly cooperation and fully support Eon’s product family.

WRITE OPERATION STATUS DQ7: DATA# Polling The EN29LV400A provides DATA# polling on DQ7 to indicate the status of the embedded operations. The DATA# polling feature is active during the embedded Programming, Sector Erase, Chip Erase, and Erase Suspend. (See Table ...

Page 17

In embedded Programming, if the sector being written to is protected, DQ6 will toggles for about 2 μs, then stop toggling without the data in the sector having changed. In Sector Erase or Chip Erase, if all selected sectors are ...

However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see the section on DQ5 is, the system ...
