Item Description
Erase Suspend allows interruption of sector erase operations to read data from or program data to a
sector not being erased. Erase suspend applies only during sector erase operations, including the
time-out period. Writing an Erase Suspend command during sector erase time-out results in
immediate termination of the time-out period and suspension of erase operation.
AS29LV160 ignores any commands during erase suspend other than Read/Reset, Program or Erase
Resume commands. Writing the Erase Resume Command continues erase operations. Addresses are
Don’t Care when writing Erase Suspend or Erase Resume commands.
Erase Suspend
AS29LV160 takes 0.2–15 µs to suspend erase operations after receiving Erase Suspend command.
To determine completion of erase suspend, either check DQ6 after selecting an address of a sector
not being erased, or poll RY/BY. Check DQ2 in conjunction with DQ6 to determine if a sector is
being erased. AS29LV160 ignores redundant writes of Erase Suspend.
While in erase-suspend mode, AS29LV160 allows reading data (erase-suspend-read mode) from or
programming data (erase-suspend-program mode) to any sector not undergoing sector erase;
these operations are treated as standard read or standard programming mode. AS29LV160 defaults
to erase-suspend-read mode while an erase operation has been suspended.
Write the Resume command 30h to continue operation of sector erase. AS29LV160 ignores
redundant writes of the Resume command. AS29LV160 permits multiple suspend/resume
operations during sector erase.
Sector Protect
When attempting to write to a protected sector, DATA polling and Toggle Bit 1 (DQ6) are activated
for about <1 µs. When attempting to erase a protected sector, DATA polling and
Toggle Bit 1 (DQ6) are activated for about <5 µs. In both cases, the device returns to read mode
without altering the specified sectors.
