Product details

Synchronous dual-port SRAM — 6 ns access, 83 MHz clock

The Cypress CY7C09579V-83AC is a synchronous dual-port SRAM organized as 32K x 36 bits, delivering 1.152 Mbit of volatile storage. 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.

Frequently asked questions

Is CY7C09579V-83AC obsolete?

Yes, the CY7C09579V-83AC is officially obsolete. No last-time-buy window remains from Cypress/Infineon. Sourcing is through independent or surplus channels only.

What is the replacement for CY7C09579V-83AC?

No official replacement order code is listed in the lifecycle record. A pin-compatible Cypress dual-port SRAM with the same 144-LQFP footprint may exist, but no validated cross-reference is on file here. Verify pinout and timing against your existing design before substituting.

What are the specifications of CY7C09579V-83AC?

The CY7C09579V-83AC is a synchronous dual-port SRAM with 1.152 Mbit organized as 32K x 36, 6 ns access time, 83 MHz clock, parallel interface, 3V to 3.6V supply, 144-LQFP package, and 0°C to 70°C operating temperature.

Where can I buy CY7C09579V-83AC?

This obsolete part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock or price figures are listed here.

What is the access time of CY7C09579V-83AC?

The access time is 6 ns, which at an 83 MHz clock leaves roughly 6 ns of bus margin for address and data propagation.
