NOTES:
1. PLCC, TQFP and STQFP 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 BUSY ."
3. To ensure that the earlier of the two ports wins.
4. t BDD is a calculated parameter and is the greater of 0, t WDD – t WP (actual) or t DDD – t DW (actual).
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 (S or L).
