71V65803S150BQG8 - Renesas Electronics

Description: The 71V65803 3.3V CMOS SRAM organized as 512K X 18. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus, it has been given the name ZBTTM, or Zero Bus Turnaround. The 71V65803 contains data I/O, address and control signal registers. In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.
