QDR II SRAM for high-throughput line cards
The CY7C1315BV18-167BZCT is a 18Mbit QDR II synchronous SRAM organized as 512K x 36, clocked at 167 MHz over a parallel interface.
At 167 MHz, the memory interface demands careful signal-integrity design on the PCB — trace-length matching and controlled impedance on the data and address lines are necessary to meet setup/hold times. The supply voltage range of 1.7V to 1.9V is tight; a clean 1.8V rail with low ripple (under 50 mV peak-to-peak) is recommended, and the 165-FBGA package (13x15 mm) requires a multi-layer board with microvia fan-out for the BGA balls.
Infineon lists the CY7C1315BV18-167BZCT as Obsolete. For BOM lines that still require this exact order code, the only sourcing path is through independent distribution or broker inventory — we can source and quote against your quantity on request.
