To protect all data in the OTP area, set the device to OTP operating mode, then issue the
PROTECT OTP AREA (80h-10h) command to page 1 in block 0 and write “00h” for the
first byte location.
After the OTP AREA is protected it cannot be programmed further. When the OTP area is
protected, the pages within the area are no longer programmable and cannot be unpro-
tected.
To use the PROTECT OTP AREA (80h-10h) command to protect the OTP area, issue the
80h command. Next, issue the following 5 address cycles: 00h-00h-01h-00h-00h. Finally,
issue the 10h command.
R/B# goes LOW for the duration of the array programming time,
STATUS (70h) command is the only valid command for reading status in OTP operating
mode. The RDY bit of the status register will reflect the state of R/B#. Use of the SELECT
LUN WITH STATUS (78h) command is prohibited.
If the PROTECT OTP AREA (80h-10h) command is issued after the OTP area has already
been protected, R/B# goes LOW for
When the device is ready, read the FAIL bit of the status register to determine if the oper-
ation passed or failed (see Table 14 on page 56).
