... Sector Protection The MBM29F400TC/BC features hardware sector protection. This feature will disable both program and erase operations in any number of sectors (0 through 10). The sector protection feature is enabled using programming equipment at the user’s site. The device is shipped with all sectors unprotected. /MBM29F400BC -55/-70/- ...

... The Sector Unprotection mode is activated by setting the RESET pin to high voltage (12 V). During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses. Once the taken away from the RESET pin, all the previously protected sectors will be protected again. Refer to Figures 17 and 24. 12 /MBM29F400BC -55/-70/-90 on address pin ...
