At higher clock rates, the 15 ns window starts to consume multiple cycles, so check the memory controller's setup/hold requirements against the part's output hold time. The 125°C ceiling means the part can sit next to a hot CPU or power stage without derating the access time — though the 15 ns spec is typically measured at 25°C, and at 125°C the internal timing margins tighten. Budget an extra 2–3 ns for temperature derating if the system runs at the upper end of the range. ## 48-VFBGA package — board-level considerations Housed in a 48-ball VFBGA (6x8 mm), this part uses a fine-pitch BGA footprint (0.5 mm ball pitch typical). The package is not hand-solderable; it requires a solder-paste stencil, reflow oven, and X-ray inspection for void detection. The small 6x8 mm body saves board space versus a TSOP-II, but the BGA's hidden solder joints make rework difficult. The CY7C1021CV26-15BAET is marked obsolete by Cypress (now Infineon). For new designs, consider a pin-compatible 3.3V asynchronous SRAM in the same 48-VFBGA footprint if the system can tolerate a higher supply — though the 2.5V–2.7V supply range is the defining voltage domain, so a 3.3V part would require level shifters on the data bus.","metaTitle":"Cypress CY7C1021CV26-15BAET 1Mbit Async SRAM, 15 ns","metaDescription":"Cypress CY7C1021CV26-15BAET 1Mbit asynchronous SRAM, 64K x 16 organization, 15 ns access time, 2.5V–2.7V supply, -40°C to 125°C industrial temp, 48-VFBGA.","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":"15 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"48-VFBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.5V ~ 2.7V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"48-VFBGA (6x8)","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/168ad2622d691f28c15ee42da7650614.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement for CY7C1021CV26-15BAET?","answer":"The part is obsolete, and Cypress has not published a successor order code."},{"question":"Can CY7C1021CV26-15BAET be replaced by a 3.3V SRAM?","answer":"Not directly. The CY7C1021CV26-15BAET operates from a 2.5V–2.7V supply. A 3.3V SRAM would exceed the absolute maximum ratings of the original part's voltage domain and would require level translation on all I/O lines if the rest of the system also runs at 2.5V. If the system can tolerate a 3.3V supply, a 3.3V asynchronous SRAM in the same 48-VFBGA footprint may be mechanically compatible, but the logic levels will not match without external level shifters."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1021CV26-15BAET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1021CV26-15BAET when reusing this data.
