Read mode AC characteristics
Write mode
The M48T35/Y is in the WRITE mode whenever W and E are low. 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 t
to the initiation of another READ or WRITE cycle. Data-in must be valid t
