Product details

Dual-port synchronous SRAM — 576Kbit at 83 MHz

The Cypress CY7C09569V-83AXCT is a 576Kbit synchronous dual-port SRAM organized as 16K x 36, with a 6 ns access time and 83 MHz clock frequency. This dual-port architecture allows simultaneous independent access from two ports, making it suitable for shared-memory applications like multiprocessor buffering, network switch packet buffers, and video frame stores where contention-free read/write from two buses is required.

The 6 ns access time and 83 MHz clock define the synchronous timing window.

Cypress (now part of Infineon) no longer manufactures this device; there is no official last-time-buy window remaining. Stock available today is date-code-limited and non-returnable — verify date codes and test samples before committing a production run. The 144-TQFP package and 3.3V supply rail are common across the Cypress dual-port SRAM family, so a pin-compatible replacement should be validated against the original timing and footprint.

Package and footprint — 144-TQFP (20x20)

The 144-LQFP package is specified.

Frequently asked questions

Is the CY7C09569V-83AXCT obsolete?

Yes, the CY7C09569V-83AXCT is officially obsolete per the lifecycle record. Cypress/Infineon no longer produces it, and no last-time-buy window remains. Sourcing is limited to the independent surplus and broker channel.

What is the replacement for CY7C09569V-83AXCT?

A pin-compatible alternative may exist within the same Cypress dual-port SRAM family (e.g., a currently active CY7C09569V variant at the same speed grade), but this must be validated against the original timing, footprint, and supply voltage. For a confirmed cross-reference, request a quote and we can research the closest active equivalent against your BOM.

What is the access time and clock frequency of CY7C09569V-83AXCT?

The access time is 6 ns, and the clock frequency is 83 MHz. The 6 ns access time defines the address-to-data valid delay; the 83 MHz clock sets the maximum synchronous operating rate.
