At 66 MHz (15 ns cycle), that margin shrinks to 2 ns or less — the layout engineer needs to keep the address and control traces short and matched. ## Industrial temperature and the 5 V rail The 5 V I/O also makes it a drop-in for legacy 5 V logic buses without external translation. ## Package and footprint — 44-TSOP II The 44-TSOP II package (0.400-inch body width, 10.16 mm) is a standard asynchronous SRAM footprint shared across many 4 Mbit and 8 Mbit parts from Cypress, ISSI, and Alliance Memory. The 16-bit data bus and 18 address lines come out in a familiar pinout that a layout engineer can route with two signal layers on a typical four-layer board. For a BOM that needs a 5 V asynchronous SRAM in the 44-TSOP II footprint, this part is a straightforward line-item that can be sourced through independent distribution without obsolescence risk.","metaTitle":"Infineon CY7C1041GN-10ZSXIT SRAM, 4Mbit, 10 ns, 44-TSOP II","metaDescription":"Infineon CY7C1041GN-10ZSXIT asynchronous SRAM, 4Mbit (256K x 16), 10 ns access time, 4.5 V to 5.5 V, -40°C to 85°C, 44-TSOP II.","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":"Tape & Reel (TR); Cut Tape (CT)","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":"Active","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":"$8.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d156dbf032b3bbfff80996b4f799a2b8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041GN-10ZSXIT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1041GN-10ZSXIT available via RFQ confirmation and what is the lead time?","answer":"Availability and current lead time are confirmed at the time of quote through our independent distribution channel.
