71V3556SA133BQG - Renesas Electronics

Description: The 71V3556 3.3V CMOS Synchronous SRAM is organized as 128K x 36. 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 71V3556 contains data I/O, address and control signal registers.
