72 Mbit QDR II SRAM at 200 MHz — what it is and where it fits
The Infineon CY7C1512AV18-200BZC is a 72 Mbit synchronous SRAM organized as 4M x 18, using the QDR II architecture. It runs at a 200 MHz clock frequency, delivering back-to-back read and write operations on separate data ports without bus-turnaround dead cycles. The 1.7 V to 1.9 V core supply and 165-ball FBGA package (15x17 mm) target high-throughput networking, telecom line cards, and test equipment where a narrow, deep memory buffer is needed. The commercial temperature range (0°C to 70°C) limits it to indoor, controlled-environment racks.
Obsolete — sourcing reality for the BOM line
The CY7C1512AV18-200BZC is officially obsolete per the manufacturer's lifecycle status. There is no listed direct successor from Infineon for this exact density and speed grade. For a BOM line that requires this part, procurement must go through the surplus and broker channel. We source and quote this part to order against an RFQ; availability and current pricing are confirmed at quote time. If a production program needs a long-term supply, a QDR II+ or QDR IV part with a compatible interface and density should be evaluated for a board respin.
Package and footprint — 165-FBGA (15x17 mm)
The part comes in a 165-ball FBGA, 15x17 mm body. The shipping medium is tray, not tape-and-reel.
