AC ELECTRICAL CHARACTERISTICS OVER THE
OPERATING TEMPERATURE AND SUPPLY VOLTAGE RANGE
NOTES:
1. Com'l Only, 0 C to +70 C temperature range. PLCC and TQFP packages only.
2. Port-to-port delay through RAM cells from the writing port to the reading port, refer to “Timing Waveform of Write with Port-to-Port Read and
3. To ensure that the earlier of the two ports wins.
4. t
5. To ensure that a write cycle is inhibited on port 'B' during contention on port 'A'.
6. To ensure that a write cycle is completed on port 'B' after contention on port 'A'.
7. “X” in part numbers indicates power rating (SA or LA).
8. Not available in DIP packages.
TIMING WAVEFORM OF WRITE WITH PORT-TO-PORT READ AND
NOTES:
1. To ensure that the earlier of the two ports wins. t
2.
3. OE = V
4. All timing is the same for the left and right ports. Port 'A' may be either the left or right port. Port "B" is opposite from port "A".
