That clock rate means the part can sustain back-to-back read and write transactions on every rising and falling edge — effectively doubling the data rate per pin pair compared to a conventional single-data-rate SRAM. The 2M x 36 organization gives you a 36-bit wide data bus, which maps cleanly to a 32-bit processor with parity or ECC overhead, or to a 36-bit wide datapath in a networking ASIC. The 1.7V to 1.9V supply rail aligns with 1.8V-core logic families, so no extra level translation is needed when interfacing to a 1.8V FPGA or controller. The surface-mount package is intended for reflow soldering; the tray shipping medium means the parts arrive in anti-static trays, not tape-and-reel, so plan for pick-and-place handling with a tray feeder. For a high-speed SRAM used in telecom line cards, test equipment, or high-end networking, this active status gives confidence for both new-design qualification and ongoing production replenishment.","metaTitle":"Cypress CY7C1564XV18-450BZC 72Mbit QDR II+ SRAM, 450 MHz","metaDescription":"Cypress CY7C1564XV18-450BZC 72Mbit synchronous SRAM, QDR II+, 450 MHz clock, 2M x 36 organization, 165-FBGA, 1.7V-1.9V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","Clock Frequency":"450 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":"$201.8473","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0f73eaba5e1601b90d29330c91a69070.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1564XV18-450BZC/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy CY7C1564XV18-450BZC and how is it quoted?","answer":"CY7C1564XV18-450BZC is sourced through independent distribution.

Both share the same 72Mbit QDR II+ architecture, 2M x 36 organization, package, and supply voltage. The -450BZC offers higher throughput for designs that need the extra margin on the bus timing budget."},{"question":"Is CY7C1564XV18-450BZC compatible with 1.8V systems?","answer":"Yes, the supply voltage range is 1.7V to 1.9V, which covers the standard 1.8V rail. The I/O levels are 1.8V HSTL-compatible, so it interfaces directly with 1.8V FPGAs, ASICs, and controllers without external level shifters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1564XV18-450BZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1564XV18-450BZC when reusing this data.
