Product details

For new designs or replacement needs, the only sourcing path is the independent market — surplus inventory, broker channels, or last-time-buy stockpiles. If you have an existing BOM line using this DDR II SRAM, now is the time to qualify a replacement or secure remaining inventory before it dries up entirely.

It clocks at 375 MHz, with data transfers on both clock edges. This DDR II SRAM is used in networking and telecom equipment needing fast, predictable access to packet buffers.

Package and supply — design-in checklist

The interface is parallel, so expect 36 data lines plus address and control signals; layout needs careful length matching at 375 MHz.

Sourcing reality — how to get this part now

Because the CY7C1550V18-375BZC is obsolete, we source it through our independent supply network — surplus stock, broker inventories, and verified last-time-buy leftovers. Availability and pricing change weekly; submit an RFQ for a firm quote against your quantity and target price.

Frequently asked questions

What is the replacement or equivalent for CY7C1550V18-375BZC?

There is no direct pin-compatible replacement announced by Cypress/Infineon for this specific DDR II SRAM. The CY7C1550 family includes other speed and temperature variants (e.g., the CY7C1550V18-375BZI with industrial temperature range), but those are also obsolete or NRND. A functional replacement would require a different DDR II SRAM with the same 2M x 36 organization, 375 MHz clock, and 1.8 V supply in a 165-ball FBGA — a narrow search that typically means a board redesign or a verified surplus buy of this exact part.
