MSM63V89C

Fast Access Mode Select (FAM)

Pin for fast read/write operations. Fast read/write is possible by keeping the FAM pin at "L" level.

The fast access mode is set or released by inputting "L" level or "H" level to the FAM pin when the

RWCK pin is at "L" level, and when tFS and tSS are satisfied.

When 1024-word data access is complete, be sure to insert a normal cycle in order to increment the

X address.

Chip Select (CS)

Input pin for disabling all input and output pins. This pin enables parallel use of multiple

MSM63V89Cs by connecting the data input and output pins.

Test (TEST)

The TEST pin is fixed to "H" level.

Turning the power ON

To stabilize the device, it is required to pause for over 100ms after the VCC reaches the specified

voltage. Then it is needed to add eight or more RWCK cycles (read cycles or pseudo data write cycles).
