The Cypress CY7C1414AV18-200BZXC is a 36 Mbit synchronous SRAM built on the QDR II architecture, clocked at 200 MHz and organized as 1M x 36. QDR II (Quad Data Rate) means the memory delivers four data words per clock cycle — two on the read port and two on the write port — giving it the bandwidth to keep up with high-performance FPGAs and network processors in packet buffers, traffic managers, and line-card lookup tables.
If the design is still in development, the safer move is to evaluate a current-production QDR II+ or QDR IV SRAM from the same family with compatible footprint and timing, but that requires a board spin and revalidation.
Package and board-level fit — 165-ball FBGA
The 165-ball FBGA (supplier device package 165-FBGA, 15x17 mm) is a fine-pitch BGA — ball pitch is typically 1.0 mm or 0.8 mm depending on the specific footprint variant. Surface-mount only, so the board needs a multi-layer stack-up with via-in-pad or dogbone fanout under the package. The commercial temperature range means no extended-temperature qualification — if the ambient in the enclosure ever exceeds 70°C, the part is outside its rated operating range.
