QDR II SRAM at 167 MHz — what it delivers
The CY7C1292DV18-167BZC is a 9 Mbit synchronous QDR II SRAM from Infineon (formerly Cypress), organized as 512K x 18. The 167 MHz clock rate and QDR II architecture — separate read and write ports, each clocking on both edges — deliver back-to-back read-write throughput without dead cycles, a key advantage for high-bandwidth buffers in networking, telecom, and test equipment where every bus turnaround matters.
Package and supply — design-in checklist
Housed in a 165-ball FBGA (13x15 mm body), the part uses a standard QDR II footprint common across density options.
Marked Obsolete by the manufacturer. For production BOMs still specifying this exact order code, the only channel is surplus inventory or broker-sourced material — date-code and authenticity verification become critical.
