N25Q128 Datasheet, PDF (77/185 Pages) Numonyx B.V – 128-Mbit, 1.8 V, multiple I/O, 4-Kbyte subsector erase on boot sectors, XiP enabled, serial flash memory with 108 MHz SPI bus interface

N25Q128 - 1.8 V
Instructions
Note:
In the case of a Page Program (PP), Program OTP (POTP), Dual Input Fast Program
(DIFP), Dual Input Extended Fast Program (DIEFP), Quad Input Fast Program (QIFP),
Quad Input Extended Fast Program (QIEFP), Subsector Erase (SSE), Sector Erase (SE),
Bulk Erase (BE), Write Status Register (WRSR), Clear Flag Status Register (CLFSR), Write
to Lock Register (WRLR), Write Configuration Register (WRVCR), Write Enhanced
Configuration Register (WRVECR), Write NV Configuration Register (WRNVCR), Write
Enable (WREN) or Write Disable (WRDI) instruction, Chip Select (S) must be driven High
exactly at a byte boundary, otherwise the instruction is rejected, and is not executed. That
is, Chip Select (S) must driven High when the number of clock pulses after Chip Select (S)
being driven Low is an exact multiple of eight.
All attempts to access the memory array are ignored during:
– Write Status Register cycle
– Write Non Volatile Configuration Register
– Program cycle
– Erase cycle
The following continue unaffected, with one exception:
– Internal Write Status Register cycle,
– Write Non Volatile Configuration Register,
– Program cycle,
– Erase cycle
The only exception is the Program/Erase Suspend instruction (PES), that can be used to
pause all the program and the erase cycles except for:
– Program OTP (POTP),
– Bulk Erase,
– Write Non Volatile Configuration Register.
The suspended program or erase cycle can be resumed by the Program/Erase Resume
instruction (PER). During the program/erase cycles, the polling instructions (both on the
Status register and on the Flag Status register) are also accepted to allow the application to
check the end of the internal modify cycles.
These polling instructions don't affect the internal cycles performing.
