1. Valid for ambient operating temperature: TA = 0 to 70 °C or –40 to 85 °C; VCC = 4.75 to 5.5 V or 4.5 to 5.5 V (except where
noted).
2.2
WRITE mode
The M48Z02/12 is in the WRITE mode whenever W and E are active. The start of a WRITE
is referenced from the latter occurring falling edge of W or E. A WRITE is terminated by the
earlier rising edge of W or E. The addresses must be held valid throughout the cycle. E or W
must return high for a minimum of tEHAX from chip enable or tWHAX from WRITE enable prior
to the initiation of another READ or WRITE cycle. Data-in must be valid tDVWH prior to the
end of WRITE and remain valid for tWHDX afterward. G should be kept high during WRITE
cycles to avoid bus contention; although, if the output bus has been activated by a low on E
and G, a low on W will disable the outputs tWLQZ after W falls.
