The OTP DATA PROTECT (A5h-10h) command is used to protect all the data in the OTP
area. After the data 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 OTP DATA PROTECT command, issue the A5h command. Next, issue the
following 5 ADDRESS cycles: 00h-00h-01h-00h-00h. Finally, issue the 10h command.
R/B# goes LOW while the OTP area is being protected. The protect command duration is
similar to a normal page programming operation,
command is the only command valid during the OTP DATA PROTECT operation. Bit 5 of
the status register will reflect the state of R/B#.
When the device is ready, read bit 0 of the status register to determine if the operation
passed or failed (see Table 9 on page 26).
1. OTP data is protected following “good” status confirmation.
The OTP DATA READ (AFh-30h) command is used to read data from a page within the
OTP area. An OTP page within the OTP area is available for reading data whether or not
the area is protected.
To use the OTP DATA READ command, issue the AFh command. Next, issue 5 ADDRESS
cycles: the first 2 ADDRESS cycles are the column address, and for the remaining 3
cycles select a page in the range of 02h-00h-00h through 0Bh-00h-00h. Finally, issue the
30h command.
