Data Sheet: Advance Information
Power Up and Power Down Sequencing
MRAM is protected from write operations whenever V
exceeds V
This time allows memory power supplies to stabilize. The /E and /W control signals should
track V
startup time. In most systems, this means that these signals should be pulled up with a
resistor so that signal remains high if the driving signal is Hi-Z during power up. Any logic
that drives /E and /W should hold the signals high with a power-on reset signal for longer
than the startup time. During power loss or brownout where V
protected and a startup time must be observed when power returns above V
