The CY7C1412AV18-200BZI is a 36Mbit QDR II synchronous SRAM from Infineon (formerly Cypress), organized as 2M x 18. The 200 MHz clock rate delivers back-to-back read and write transactions on separate data ports without dead cycles — the defining advantage of the QDR II architecture over conventional synchronous SRAM. For a design that needs sustained throughput in a networking buffer or high-speed cache, this part eliminates the bus-turnaround penalty that standard NoBL or pipelined SRAM incurs.
Supply and temperature — industrial-grade fit
The 165-FBGA (15x17 mm) package uses a 1 mm ball pitch — fan-out is manageable on a standard 4-layer PCB with microvias, but the inner balls need at least one via-in-pad or a blind-via stack if you are routing all 18 data bits per port.
Infineon has discontinued the CY7C1412AV18-200BZI, and no direct replacement has been listed as a successor. There is no factory lead time to rely on; the procurement decision hinges on finding verified inventory in the open market.
