EN25P10

Status Register. The Status Register contains a number of status and control bits that can be read or set

(as appropriate) by specific instructions.

BUSY bit. The BUSY bit indicates whether the memory is busy with a Write Status Register, Program or

Erase cycle.

WEL bit. The Write Enable Latch (WEL) bit indicates the status of the internal Write Enable Latch.

BP1, BP0 bits. The Block Protect (BP1, BP0) bits are non-volatile. They define the size of the area to be

software protected against Program and Erase instructions.

SRP bit. The Status Register Protect (SRP) bit is operated in conjunction with the Write Protect (WP#)

signal. The Status Register Protect (SRP) bit and Write Protect (WP#) signal allow the device to be put in

the Hardware Protected mode. In this mode, the non-volatile bits of the Status Register (SRP, BP1, BP0)

become read-only bits.

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 EN25P10

provides the following data protection mechanisms:

Power-On Reset and an internal timer (t

) can provide protection against inadvertent changes

PUW

while the power supply is outside the operating specification.

Program, Erase and Write Status Register instructions are checked that they consist of a number of

clock pulses that is a multiple of eight, 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:

–

Power-up

– Write Disable (WRDI) instruction completion or Write Status Register (WRSR) instruction

completion or Page Program (PP) instruction completion or Sector Erase (SE)instruction

completion or Bulk Erase (BE) instruction completion or

The Block Protect (BP1, BP0) bits allow part of the memory to be configured as read-only. This is

the Software Protected Mode (SPM).

The Write Protect (WP#) signal allows the Block Protect (BP1, BP0) bits and Status Register Protect

(SRP) bit to be protected. This is the Hardware Protected Mode (HPM).

In addition to the low power consumption feature, the Deep Power-down mode offers extra software

protection from inadvertent Write, Program and Erase instructions, as all instructions are ignored

except one particular instruction (the Release from Deep Power-down instruction).

Hold Function

The Hold (HOLD) signal is used to pause any serial communications with the device without resetting the

clocking sequence. However, taking this signal Low does not terminate any Write Status Register,

Program or Erase cycle that is currently in progress.

or modifications due to changes in technical specifications.
