The 36-bit word width leaves room for parity or ECC on a 32-bit data bus — a common choice in NPU and FPGA-attached memory. Supply runs at 1.7V to 1.9V, so the board's core rail needs tight regulation; the 1.7V floor is the number to check during brownout or cold-crank analysis. ## QDR II+ — why the bus-turnaround matters Standard synchronous SRAMs insert dead cycles when switching from read to write (or write to read). QDR II+ eliminates that turnaround penalty by dedicating separate data ports for read and write, allowing back-to-back transactions at full clock rate. For a 450 MHz part, that means no wasted cycles on a congested memory bus — directly relevant for line-rate packet processing where every clock counts. The 2M x 36 organization also means the device can handle a 32-bit data word plus a 4-bit sideband (tag, parity, or ECC) in a single access, reducing the total device count on the board. The device comes in a 165-ball FBGA measuring 13x15 mm (supplier device package 165-FBGA). It is a surface-mount BGA; the ball pitch and layout dictate the fan-out via pattern and the number of PCB layers needed to escape the inner balls. Decoupling should follow the manufacturer's recommendation — typically a 0.1 µF cap per supply ball pair, placed as close to the balls as the via pattern allows. The Tray shipping medium is standard for this package; if your pick-and-place feeder expects tape, verify the tray-to-tape conversion with your assembler before committing the line.","metaTitle":"CY7C2564XV18-450BZXI SRAM, QDR II+, 72Mbit, 450 MHz","metaDescription":"Cypress CY7C2564XV18-450BZXI 72Mbit QDR II+ synchronous SRAM, 450 MHz clock, 1.7V–1.9V supply, -40°C to 85°C, 165-ball FBGA.","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":"CY7C2564","Memory Organization":"2M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$214.0625","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/71535f223eae29c195695927ea437893.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can CY7C2564XV18-450BZXI be replaced by CY7C2564XV18-450BZXC?","answer":"The two are pin-compatible and functionally identical at the same clock speed, but the 'C' variant lacks the extended temperature rating.
