That clock rate means the data bus toggles on both edges, so the effective data rate per pin is 1.1 Gbps — the limiting factor in a high-throughput pipeline is often the controller's own timing closure, not the memory's access window. The 1.7 V to 1.9 V core supply puts it in the low-voltage SRAM class — the narrower rail tolerance (200 mV window) demands a clean local regulator with <10 mV ripple at the BGA balls; a shared 1.8 V rail from a switching converter without post-filtering will push the core out of spec under load transients. ## Package and board-fit — 165-ball FBGA Housed in a 165-ball FBGA measuring 13x15 mm (supplier device package 165-FBGA). The 0.80 mm ball pitch is standard for this density — a 4-layer PCB with via-in-pad or microvias under the BGA is the practical minimum for fan-out. The package is surface-mount only, shipped in trays. The 550 MHz clock at the hot end (85°C) still meets the timing window — the derating curve is in the datasheet's AC timing table, not the DC specs. That means it is still a valid choice for new designs and production builds without an imminent obsolescence risk.","metaTitle":"Infineon CY7C25682KV18-550BZXI 72Mbit SRAM, 550 MHz","metaDescription":"Infineon CY7C25682KV18-550BZXI 72Mbit synchronous DDR II+ SRAM, 550 MHz clock, 4M x 18 organization, 1.7-1.9V, -40 to 85°C, 165-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, DDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C25682","Memory Organization":"4M x 18","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f19132fc37b3d01e4f681995de6fd1cb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory organization and interface of this SRAM?","answer":"Organized as 4M x 18 (72 Mbit total) with a parallel memory interface.
