10. Absolute Maximum Ratings
November 27, 2007 S29AL008D_00_A10
After the sector erase command sequence is written, the system should read the status on DQ7 (Data#
Polling) or DQ6 (Toggle Bit I) to ensure the device accepted the command sequence, and then read DQ3. If
DQ3 is 1, the internally controlled erase cycle started; all further commands (other than Erase Suspend) are
ignored until the erase operation is complete. If DQ3 is 0, the device accepts additional sector erase
commands. To ensure the command is accepted, the system software should check the status of DQ3 prior
to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last
command might not be accepted.
Notes
1. DQ5 switches to 1 when an Embedded Program or Embedded Erase operation exceeds the maximum timing limits. See
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
Notes
1. Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions, input or I/O pins may undershoot V
2. Minimum DC input voltage on pins A9, OE#, and RESET# is –0.5 V. During voltage transitions, A9, OE#, and RESET# may undershoot
3. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second.
4. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only;
