Protection modes
There are protocol-related and specific hardware and software protection modes. They are
described below.
SPI Protocol-related protections
This applies to all three protocols. The environments where non-volatile memory devices
are used can be very noisy. No SPI device can operate correctly in the presence of
excessive noise. To help combat this, the N25Q128 features the following data protection
mechanisms:
This bit is also returned to its reset state after all the analogous events in DIO-SPI and QIO-
SPI protocol modes.
Specific hardware and software protection
There are two software protected modes, SPM1 and SPM2, that can be combined to protect
the memory array as required. The SPM2 can be locked by hardware with the help of the W
input pin.
Power On Reset and an internal timer (tVTW) can provide protection against
inadvertent changes while the power supply is outside the operating specification.
Program, Erase, WRSR, WRLR, WRNVCR, WRVCR, WRVECR instructions
instructions are checked to ensure the instruction includes a number of clock pulses
that is a multiple of a byte before they are accepted for execution.
All instructions that modify data must be preceded by a Write Enable (WREN)
instruction to set the Write Enable Latch (WEL) bit. This bit is returned to its reset state
by the following events (in Extended SPI protocol mode):
