Organized 2M x 36, it clocks at 366 MHz, giving a peak bandwidth of about 14.7 Gbps on a 36-bit bus. The 1.7V to 1.9V core supply keeps I/O levels in the 1.8V range, matching low-voltage FPGA and ASIC interfaces. This part is built for high-throughput, low-latency lookup tables, packet buffers, and cache memory in networking switches, baseband processors, and test equipment — applications where every nanosecond of read-to-write turnaround matters. At 366 MHz, the QDR II+ interface delivers back-to-back transactions without idle cycles between read and write. For a system moving 36-bit words, that translates to roughly 1.46 GWords/s peak. The timing closure challenge is real — the 165-ball FBGA footprint (13x15 mm) needs careful signal-integrity layout, with matched trace lengths and adequate decoupling right at the BGA balls. This means Cypress (now Infineon) has stopped production; there is no active last-time-buy window. For new designs, a current-generation QDR II+ or QDR IV SRAM from the same vendor would be the natural migration path, but that requires a board respin and timing revalidation. The 165-LBGA (supplier device package 165-FBGA, 13x15 mm) is a fine-pitch BGA.","metaTitle":"Cypress CY7C1564XV18-366BZXC 72Mbit QDR II+ SRAM, 366 MHz","metaDescription":"Cypress CY7C1564XV18-366BZXC 72Mbit QDR II+ synchronous SRAM, 366 MHz clock, 2M x 36 organization, 1.7V-1.9V supply, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"366 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1564","Memory Organization":"2M x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$214.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0f73eaba5e1601b90d29330c91a69070.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1564XV18-366BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1564XV18-366BZXC obsolete?
