2.7

Write Protect (W) or Top Sector Lock (TSL)

●

The Write Protect function is available in the T9HX process only (see Important

note on page 6).

The Write Protect (W) input is used to freeze the size of the area of memory that is

protected against write, program and erase instructions (as specified by the values in

theBP1 and BP0 bits of the Status Register. See Section 6.4: Read Status Register

(RDSR) for a description of these bits).

●

The Top Sector Lock function is available in the T7X process only (see Important

note on page 6).

The input signal sets the device in the Hardware Protected mode, when Top Sector

Lock (TSL) is connected to VSS, causing the top 256 pages (upper addresses) of the

memory to become read-only (protected from write, program and erase operations).

When Top Sector Lock (TSL) is connected to VCC, the top 256 pages of memory

behave like the other pages of memory.

2.8

VCC supply voltage

VCC is the supply voltage.

2.9

VSS ground

VSS is the reference for the VCC supply voltage.
