Read mode AC characteristics
Note:
Valid for ambient operating temperature: TA = 0 to 70°C; VCC = 4.75 to 5.5 V or 4.5 to 5.5 V
(except where noted).
2.2
Write mode
The M48T08/18/08Y is in the WRITE mode whenever W, E1, and E2 are active. The start of
a WRITE is referenced from the latter occurring falling edge of W or E1, or the rising edge of
E2. A WRITE is terminated by the earlier rising edge of W or E1, or the falling edge of E2.
The addresses must be held valid throughout the cycle. E1 or W must return high or E2 low
for a minimum of tE1HAX or tE2LAX 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; however, if the output bus has been activated by a low on E1 and G
and a high on E2, a low on W will disable the outputs tWLQZ after W falls.
