At 20 ns, the memory can deliver data within one clock edge of a 50 MHz controller — but the address-to-output propagation, not the clock rate, is the binding constraint for hold-time margin on the bus. If the rest of the board has migrated to lower voltages, a level translator on the address/data bus is needed to avoid over-stressing the SRAM inputs or under-driving the output buffers. ## 44-SOJ package — footprint and reflow Housed in a 44-lead SOJ (Small Outline J-lead) package, 0.400-inch body width, 10.16 mm. The J-lead footprint is standard for wide-body SOJ — the same pad pattern used across the Cypress/Infineon 4 Mbit async SRAM family. Tape & Reel packaging feeds directly into pick-and-place; no tube handling required. The commercial temperature grade (0°C to 70°C) limits this to indoor, non-condensing environments. No industrial or automotive qualification — not suitable for engine bay, outdoor telecom cabinets without climate control, or extended cold storage. For a BOM that requires this exact speed grade (20 ns) and package (44-SOJ), the only path is spot-market procurement.","metaTitle":"CY7C1041BNL-20VXCT Infineon 4Mbit Async SRAM, 20ns, 44-SOJ","metaDescription":"Infineon CY7C1041BNL-20VXCT 4Mbit (256K x 16) asynchronous SRAM, 20 ns access time, 4.5-5.5 V 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":"Tape & Reel (TR)","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e690fd960bc194496f6e212a352c5ee.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1041BNL-20VXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1041BNL-20VXCT when reusing this data.
