POWER SUPPLY

Power Down

The memory provides Reset/Power Down control

input RP. The Power Down function can be acti-

vated only if the relevant Configuration Register bit

is set to ’1’. In this case, when the RP signal is

the outputs are in high impedance.If RP is pulled

content is no longer valid (see Reset/Power Down

input description).

Power Up

The memory Command Interface is reset on Pow-

er Up to Read Array. Either E or W must be tied to

and the possibility to write a command on the first

rising edge of W.

Supply Rails

Normal precautions must be taken for supply volt-

age decoupling; each device in a system should

trace widths should be sufficient to carry the re-

Table 21. Program, Erase Times and Program, Erase Endurance Cycles

Note: 1. Max values refer to the maximum time allowed by the internal algorithm before error bit is set. Worst case conditions program or

erase should perform significantly better.

2. Excludes the time needed to execute the sequence for program instruction.
