If your processor's memory controller has a setup/hold window narrower than 2 ns, budget a series resistor on the data lines to damp reflections — the 44-TSOP II leadframe is not impedance-controlled. ## Industrial temperature grade — where it goes The 5 V supply rail is common in those environments — many legacy backplanes still distribute 5 V, and a local LDO would add cost. If your design lives in a climate-controlled server room, the commercial-grade sibling (CY7C1041D-10ZSXI) saves a few cents, but the industrial part gives you a single BOM for both indoor and outdoor variants. No new factory orders are accepted; the only available stock sits in independent distribution channels.","metaTitle":"Infineon CY7C1041D-10ZSXIT 4Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1041D-10ZSXIT 4Mbit (256K x 16) asynchronous SRAM with 10 ns access time, 4.5-5.5 V supply, -40°C to 85°C.","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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2bd55a639f96a1b8545cf8c89e3919b0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C1041D-10ZSXIT?","answer":"Submit an RFQ for current availability and pricing — we confirm both at quote time.
