This tight timing budget demands careful signal-integrity simulation and matched-length routing on the data and address buses — a point often missed when swapping in a slower-grade SRAM. The 250 MHz clock frequency supports back-to-back read/write transactions without dead cycles, critical for high-throughput packet processing in networking equipment. The synchronous interface simplifies controller design by eliminating the asynchronous handshake overhead. ## Industrial temperature and FBGA package — deployment context For production runs that already have this SRAM in the BOM, the only reliable channel is independent distribution — verified date-code lots, sourced against an RFQ. The FBGA package and 2.5V supply rail are not drop-in compatible with the more common 3.3V synchronous SRAMs, so a board redesign is required if a substitute is needed. When sourcing obsolete BGA memory, date-code provenance matters: lots manufactured within two years of the last-time-buy date are preferable, as moisture sensitivity and solder-ball oxidation degrade over time. We quote each RFQ against current available stock, confirming the date code and quantity before committing the BOM line.","metaTitle":"Infineon CY7C1440AV25-250BZXI 36Mbit SRAM, 2.6 ns, 250 MHz","metaDescription":"Infineon CY7C1440AV25-250BZXI 36Mbit synchronous SDR SRAM, 2.6 ns access time, 250 MHz, industrial temp -40°C to 85°C, 165-FBGA.","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, SDR","Access Time":"2.6 ns","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.375V ~ 2.625V","Base Product Number":"CY7C1440","Memory Organization":"1M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$98.0900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6f102738a4133e0c36d8952b60dbb5eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1440AV25-250BZXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1440AV25-250BZXI obsolete?","answer":"Yes, Infineon has listed the CY7C1440AV25-250BZXI as Obsolete.
