The 400 MHz clock rate delivers a peak data rate of 800 MT/s across the 18-bit-wide data bus, a fit for high-bandwidth buffer applications in networking line cards, test equipment, or FPGA-attached data paths that need deterministic read/write latency without DRAM refresh overhead. The memory is organized as 4M x 18 bits — the 18-bit word width maps cleanly to a 16-bit data bus with two parity/ECC bits or to an 18-bit raw-data path. The parallel interface connects directly to a memory controller without serialization latency, which is the reason this class of SRAM persists in designs where QDR or RLDRAM would add controller complexity. ## Package and supply — board-fit constraints The supplier device package is 165-FBGA (13x15) — the 13x15 mm footprint and ball map are the critical dimensions for the PCB layout; the stencil aperture and solder-paste volume for the centre thermal balls must follow the JEDEC design guide for this ball count. Supply voltage is 1.7 V to 1.9 V — a single core rail, but the 200 mV tolerance band means the regulator must hold regulation within ±5 % across load transients. A standard 1.8 V LDO with 1 % initial accuracy and 50 mV dropout at the SRAM's peak current (typically 400–500 mA for a 400 MHz DDR II+ part) keeps the rail inside the window. ## Sourcing posture for an obsolete SRAM Because the CY7C2568KV18-400BZC is officially obsolete, no authorized distributor holds factory stock. The part is sourced through independent channels that maintain surplus inventory from end-of-life buy lots or overstock. Each lot is verified for authenticity and traceability before shipment; the buyer receives a certificate of conformance with the order. A functional replacement would require a board spin — the 165-ball FBGA footprint and the DDR II+ timing parameters are specific to this die revision. The procurement desk should budget for a one-time BOM qualification if the existing design must be migrated to an active SRAM family.","metaTitle":"CY7C2568KV18-400BZC Infineon 72Mbit SRAM, 400 MHz, FBGA","metaDescription":"Infineon CY7C2568KV18-400BZC 72Mbit DDR II+ synchronous SRAM, 400 MHz clock, 4M x 18 organization.","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, DDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C2568","Memory Organization":"4M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$283.4100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/da793dcd869ea399d19b8169de2bacc5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory organization and interface of CY7C2568KV18-400BZC?","answer":"The memory is organized as 4M x 18 bits (72 Mbit total) with a parallel interface.
