Signal description

M95040, M95020, M95010

10/42

When VCC has passed the POR threshold voltage, the device is reset and in the following

state:

●

in Standby Power mode

●

deselected (at next Power-up, a falling edge is required on Chip Select (S) before any

instruction can be executed)

●

not in the Hold Condition Status register state:

–

the Write Enable Latch (WEL) is reset to 0

–

the Write In Progress (WIP) is reset to 0. The SRWD, BP1 and BP0 bits of the

Status Register are at the same logic level as when the device was last powered

down (they are non-volatile bits)

2.8.4

Power-down

At Power-down (continuous decrease of VCC), as soon as VCC drops from the normal

operating voltage to below the Power On Reset threshold voltage, the device stops

responding to any instruction sent to it.

At Power-down, the device must be deselected and in Standby Power mode (that is there

should be no internal Write cycle in progress). Chip Select (S) should be allowed to follow

the voltage applied on VCC.
