71V65703中文资料3.3V 256K x 36 ZBT Synchronous 3.3V I/O Flowthrough SRAM数据手册Renesas规格书

描述 Description

The 71V65703 3.3V CMOS SRAM is organized as 256K 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 71V65703 contain address, data-in and control signal registers. The outputs are flow-through (no output data register).In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.
