WRITE OPERATIONS

The CAT25010/20/40 device powers up into a write

disable state. The device contains a Write Enable Latch

(WEL) which must be set before attempting to write to the

memory array or to the status register. In addition, the

address of the memory location(s) to be written must be

outside the protected area, as defined by BP0 and BP1 bits

from the status register.

Write Enable and Write Disable

The internal Write Enable Latch and the corresponding

Status Register WEL bit are set by sending the WREN

instruction to the CAT25010/20/40. Care must be taken to

take the CS input high after the WREN instruction, as

otherwise the Write Enable Latch will not be properly set.

WREN timing is illustrated in Figure 3. The WREN

instruction must be sent prior to any WRITE or WRSR

instruction.

The internal write enable latch is reset by sending the

WRDI instruction as shown in Figure 4. Disabling write

operations by resetting the WEL bit, will protect the device

against inadvertent writes.
