Intel StrataFlash Wireless Memory (L18)
Notes:
1.
"Illegal commands" include commands outside of the allowed command set (allowed commands: 40H
[pgm], 20H [erase], etc.)
2.
If a "Read Array" is attempted from a busy partition, the result will be invalid data. The ID and Query
data are located at different locations in the address map.
3.
1st and 2nd cycles of "2 cycles write commands" must be given to the same partition address, or
unexpected results will occur.
4.
To protect memory contents against erroneous command sequences, there are specific instances in a
multi-cycle command sequence in which the second cycle will be ignored. For example, when the device
is program suspended and an erase setup command (0x20) is given followed by a confirm/resume
command (0xD0), the second command will be ignored because it is unclear whether the user intends
to erase the block or resume the program operation.
