Product details

QDR II synchronous SRAM at 250 MHz

The CY7C1911KV18-250BZCT is a QDR II (Quad Data Rate) synchronous SRAM from Infineon, offering 18 Mbit density in a 2M x 9 organization. The 250 MHz clock rate delivers back-to-back read/write transactions without dead cycles — critical for high-throughput networking or telecom line cards where bus turnaround latency directly impacts packet processing throughput.

Supply and temperature envelope

Packaged in a 165-ball FBGA (13x15 mm) with a parallel memory interface. The 0.80 mm ball pitch requires careful PCB fan-out; a four-layer board with a dedicated VDDQ plane is typical to keep supply noise within the 1.7 V – 1.9 V window.

Infineon lists the CY7C1911KV18-250BZCT as Obsolete. No official successor or pin-compatible drop-in replacement is cited in the lifecycle record. For existing BOM lines, the only sourcing path is through independent or franchise-distributor inventory — last-time buy windows have closed.

Frequently asked questions

What is the replacement for CY7C1911KV18-250BZCT?

No official pin-compatible replacement is cited in the lifecycle record. For a functionally equivalent QDR II SRAM, consider other 18 Mbit parts in the CY7C1911KV18 base number family (e.g., CY7C1911KV18-250BZXI) — but confirm package, temperature grade, and timing compatibility against your BOM.
