IDT 79RC32355
Note:
The RC32355 provides bus turnaround cycles to prevent bus contention when going from a read to write, write to read, and during
external bus ownership. For example, there are no cycles where an external device and the RC32355 are both driving. See the chapters
“Device Controller,” “Synchronous DRAM Controller,” and “Bus Arbitration” in the RC32355 User Reference Manual.
