Product details

QDR II SRAM for high-bandwidth data-path applications

It is designed for applications that demand sustained read and write bandwidth without bus-turnaround dead cycles — the QDR II architecture provides separate read and write ports, eliminating the need to alternate direction on a shared bus. It is supplied in a 165-ball FBGA (15x17 mm) package for surface-mount assembly.

A 375 MHz clock corresponds to a 2.67 ns cycle time. With QDR II's double-data-rate operation on both read and write ports, the effective data window per pin is under 1.34 ns. The PCB designer must budget for trace-length matching, controlled impedance, and adequate decoupling on the 1.7V–1.9V rail to maintain signal integrity. The 165-FBGA package with its fine ball pitch demands careful fan-out planning — the 15x17 mm footprint does not leave room for oversized vias under the body.

Any buyer adding this to a new BOM should qualify an alternate QDR II SRAM from the same or a compatible family.

Frequently asked questions

What is the replacement for CY7C1565V18-375BZC?

The QDR II SRAM family from Cypress/Infineon includes multiple density and speed grades, but a pin-compatible direct successor is not confirmed. A cross-reference search against other 2M x 36 QDR II devices in a 165-FBGA package is recommended for dual-sourcing or replacement qualification.

What voltage does CY7C1565V18-375BZC require?

The CY7C1565V18-375BZC operates from a 1.7V to 1.9V core supply. This is a low-voltage rail that must be clean and well-regulated — any ripple or droop at 375 MHz clock rates will directly impact timing margin on the QDR II bus.

What is the clock frequency of CY7C1565V18-375BZC?

The maximum clock frequency is 375 MHz. With QDR II's double-data-rate operation, this yields a 750 MHz effective data rate on each of the read and write ports.
