71V547 Block Diagram - 128K x 36
Description
The 71V547 3.3V CMOS SRAM is organized as 128K x 36 bits. 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 Turn-around. The 71V547 contains 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.
