10.2 WRITE PROTECTION
Applications that use non-volatile memory must take into consideration the possibility of noise and other
adverse system conditions that may compromise data integrity. To address this concern the W25Q16BV
provides several means to protect data from inadvertent writes.
10.2.1 Write Protect Features
?

Device resets when VCC is below threshold
Time delay write disable after Power-up
Write enable/disable instructions and automatic write disable after program and erase
Software and Hardware (/WP pin) write protection using Status Register
Write Protection using Power-down instruction
Lock Down write protection until next power-up (1)
One Time Program (OTP) write protection (1)
Note 1: These features are available upon special order. Please refer to Ordering Information.
Upon power-up or at power-down, the W25Q16BV will maintain a reset condition while VCC is below the
threshold value of V WI , (See Power-up Timing and Voltage Levels and Figure 32). While reset, all
operations are disabled and no instructions are recognized. During power-up and after the VCC voltage
exceeds V WI , all program and erase related instructions are further disabled for a time delay of t PUW . This
includes the Write Enable, Page Program, Sector Erase, Block Erase, Chip Erase and the Write Status
Register instructions. Note that the chip select pin (/CS) must track the VCC supply level at power-up until
the VCC-min level and t VSL time delay is reached. If needed a pull-up resister on /CS can be used to
accomplish this.
After power-up the device is automatically placed in a write-disabled state with the Status Register Write
Enable Latch (WEL) set to a 0. A Write Enable instruction must be issued before a Page Program, Sector
Erase, Chip Erase or Write Status Register instruction will be accepted. After completing a program,
erase or write instruction the Write Enable Latch (WEL) is automatically cleared to a write-disabled state
of 0.
Software controlled write protection is facilitated using the Write Status Register instruction and setting
the Status Register Protect (SRP0, SRP1) and Block Protect (SEC,TB, BP2, BP1 and BP0) bits. These
settings allow a portion or all of the memory to be configured as read only. Used in conjunction with the
Write Protect (/WP) pin, changes to the Status Register can be enabled or disabled under hardware
control. See Status Register for further information. Additionally, the Power-down instruction offers an
extra level of write protection as all instructions are ignored except for the Release Power-down
instruction.
