Cypress has placed this part in Last Buy status. That means the manufacturer has announced a final order window — once that window closes, no more units will be produced. For any design currently using this SRAM, the procurement decision is immediate: either place a last-time-buy (LTB) order to cover the remaining production run, or qualify a replacement. This SRAM comes in a 165-ball LBGA (13x15 mm body), surface-mount only. That's a fine-pitch BGA — the balls are small and the pitch is tight. If you're planning to hand-rework this part, you'll need a hot-air station with a nozzle that covers the full array, a good stencil for reballing, and X-ray after placement to check for shorts or head-in-pillow. The 1.7V to 1.9V supply rail is narrow; make sure your power module stays inside that window under load, or the part may not initialize cleanly.","metaTitle":"Cypress CY7C2565XV18-633BZXC 72Mbit QDR II+ SRAM, 633 MHz","metaDescription":"Cypress CY7C2565XV18-633BZXC 72Mbit (2M x 36) QDR II+ synchronous SRAM, 633 MHz clock, 165-FBGA, commercial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","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":"Last Time Buy","Clock Frequency":"633 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C2565","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":"$427.2500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eba0839ecbb3e90c489517bff5a03dff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C2565XV18-633BZXC?","answer":"Cypress has not published an official successor order code for this part. A direct pin-compatible drop-in from the same manufacturer is not listed. For a replacement, you would need to evaluate other QDR II+ SRAMs in the 72Mbit / 633 MHz class from vendors like Renesas or GSI Technology, but those would require a board respin or at minimum a timing and footprint review."},{"question":"Is CY7C2565XV18-633BZXC obsolete?","answer":"It is in Last Buy status — the manufacturer has announced a final order window, but production has not yet ceased. Once the LTB window closes, it will become obsolete. Act now if you need to secure inventory for ongoing production."},{"question":"What is the clock frequency of CY7C2565XV18-633BZXC?","answer":"The clock frequency is 633 MHz. At that rate, the QDR II+ architecture delivers read and write data on both clock edges, giving an effective 1.266 Gbps per pin pair."},{"question":"What is the memory organization of CY7C2565XV18-633BZXC?","answer":"The memory is organized as 2M words by 36 bits — 2 meg locations, each 36 bits wide. That's a total of 72 megabits."},{"question":"What package does CY7C2565XV18-633BZXC use?","answer":"It uses a 165-ball LBGA (13x15 mm body), also listed as 165-FBGA. Surface-mount only.
