The 36-bit data bus at double data rate delivers a theoretical peak bandwidth of 14.4 Gbit/s — the limiting factor in a high-throughput FIFO or packet buffer application is the controller's ability to sustain back-to-back reads and writes without bus turnaround penalties. The parallel memory interface uses separate read and write ports, eliminating the dead cycle between read-to-write transitions that single-port SRAMs incur. This matters for network switch buffers and radar signal processors where every clock cycle carries payload data. ## Temperature grade and supply rail The 1.7V–1.9V supply rail aligns with the 1.8V core voltage common in high-performance FPGAs and ASICs, so the SRAM can share the same power rail without an extra regulator. The 165-FBGA package (13x15 mm) uses a 1.0 mm ball pitch — hand-soldering is impractical; a reflow profile with a peak temperature of 245°C and a pre-bake at 125°C for 8 hours if the moisture sensitivity level exceeds MSL 3 is the standard assembly practice. The footprint requires a 4-layer PCB minimum for signal fan-out. ## Obsolete lifecycle — sourcing route A board spin is required to migrate to a different package or memory family.","metaTitle":"CY7C1315BV18-200BZI QDR II SRAM, 18Mbit, 200 MHz, Obsolete","metaDescription":"Infineon CY7C1315BV18-200BZI QDR II synchronous SRAM, 18Mbit (512K x 36), 200 MHz, 1.7-1.9V, 165-FBGA, -40°C to 85°C.
