The 6 ns access time and 83 MHz clock rate support back-to-back read/write cycles without dead cycles on either port, which matters for shared-memory arbitration in packet buffers, FIFO emulation, or multiprocessor mailboxes where bus-turnaround latency directly impacts throughput. The parallel interface runs on a 3V to 3.6V supply, and the part is housed in a 144-LQFP (20x20 mm) package for surface-mount assembly.","metaTitle":"Cypress CY7C09579V-83AC SRAM, 1.152Mbit Dual-Port, 6 ns","metaDescription":"Cypress CY7C09579V-83AC synchronous dual-port SRAM, 1.152Mbit (32K x 36), 6 ns access time, 83 MHz clock.
