This is a word-wide, parallel-interface memory intended for use as fast scratchpad, cache, or buffer in embedded systems that need deterministic read/write timing without refresh overhead. The 20 ns access time means the part can keep up with bus cycles down to 50 MHz without wait states, assuming the host memory controller meets the setup and hold windows. Supply range is 4.5V to 5.5V, which ties it to legacy 5V logic families — not a 3.3V-only bus. Cypress no longer manufactures it, so new-stock procurement moves to the independent channel. Housed in a 44-SOJ surface-mount package (44-BSOJ, 0.400\" body width, 10.16 mm width).","metaTitle":"Cypress CY7C1041BNL-20VXC 4Mbit Async SRAM, 20 ns, 44-SOJ","metaDescription":"Cypress CY7C1041BNL-20VXC 4Mbit asynchronous SRAM, 256K x 16, 20 ns access time, 5V supply, 44-SOJ.","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":"Tube","Technology":"SRAM - Asynchronous","Access Time":"20 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-BSOJ (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":"0°C~70°C(TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2294204682dd19c9a5f4fc12a8190d63.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041BNL-20VXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1041BNL-20VXC obsolete?","answer":"Yes, the lifecycle status is obsolete.
