M66252P/FP

1152 x 8-BIT LINE MEMORY (FIFO)

FUNCTION

When the status of write enable input WE is “L,” data on D0

thru D7 are written on the memory synchronously with write

clock input WCK rise edges. At this time, write address

counter executes counting.

The following write-related operations are also performed

synchronously with WCK rise edges.

When WE is “H,” writing on memory is inhibited, and write ad-

dress counter stops counting.

When write reset input WRES is “L,” write address counter is

initialized.

When read enable input RE is “L,” data on memory are out-

put to Q0 thru Q7 synchronously with read clock input RCK

rise edges. At this time, read address counter executes

counting.

The following read-related operations are also performed

synchronously with RCK rise edges.

When RE is “H,” reading from memory is inhibited, and read

address counter stops counting. The status of Q0 thru Q7 be-

comes high-impedance.

When read reset input RRES is “L,” read address counter is

initialized.
