Frequently asked questions
Is CY7C185-25VC obsolete?
Yes, the CY7C185-25VC is obsolete. Cypress (now Infineon) no longer manufactures this part. It is available through surplus and independent distribution channels, sourced and quoted to order against an RFQ.
What is the replacement for CY7C185-25VC?
No official replacement part is listed by Cypress for the CY7C185-25VC. A functionally equivalent 64Kbit asynchronous SRAM in a 28-SOJ package with 25 ns access time would need to be validated by the design team for pin compatibility and timing.
What is the package type of CY7C185-25VC?
The CY7C185-25VC is packaged in a 28-SOJ (Small Outline J-lead) surface-mount package, 7.62 mm body width, 0.300-inch row spacing.
What is the access time of CY7C185-25VC?
The access time is 25 ns, with an equal 25 ns write cycle time for word and page operations.
