Description
The 71V3578 3.3V CMOS SRAM is organized as 256K x 18. The 71V3578 SRAM contains write, data, address and control registers. The burst mode feature offers the highest level of performance to the system designer, as it can provide four cycles of data for a single address presented to the SRAM.
