MSM6684B

NOTES ON POWER-UP

MSM6684B has built-in board bias generation and inner power supply circuits. Thus, energization

must be followed by a pause period of 1 ms or more for internal circuit stabilization. Furthermore,

the TEST pin must be brought "L" concurrently with or prior to VCC, and all clock input pins and TEST

pins must be brought "H" concurrently with or prior to VCC.

To achieve proper operation of internal circuits, the initial pause above must be followed by

minimum ten dummy read cycles with RWCK.

NOTES ON SUPPLY VOLTAGE VARIATION

When using MSM6684B, take precautions so that the supply voltage does not vary over one volt

within a period of 1,000ms or less in the active state.
