Buyers should secure their lifetime buy quantities or qualify a replacement before supply dries up. The 15 ns access time defines the speed grade of this SRAM. For a system running a 66 MHz bus (15 ns cycle), this part provides zero-wait-state reads if the controller's address-to-data valid window fits within 15 ns. At higher clock rates or with slower controllers, the 15 ns rating gives a clean timing margin that avoids bus contention or data corruption. ## 2.5 V – 2.7 V supply — narrow rail, no margin for droop The supply range is 2.5 V to 2.7 V, a tighter window than the typical 2.5 V ±5% or 2.7 V ±10% parts. This means the board must deliver a regulated 2.5 V or 2.7 V rail within 100 mV of the target. If the design already has a 2.5 V or 2.7 V supply, this part drops in cleanly; if the rail is 3.3 V or 1.8 V, an additional regulator is needed. The 44-TSOP II package with surface-mount leads handles the thermal cycling without solder-joint fatigue common in larger BGA packages.","metaTitle":"Infineon CY7C1021CV26-15ZSXE 1 Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C1021CV26-15ZSXE asynchronous SRAM: 1 Mbit (64K x 16), 15 ns access time, 2.5 V–2.7 V, -40°C to 125°C, 44-TSOP II.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Asynchronous","Access Time":"15 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Last Time Buy","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":"44-TSOP II","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2896","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/71b16cf5915ec06f6936670e2056aaa0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021CV26-15ZSXE/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021CV26-15ZSXE obsolete?","answer":"The CY7C1021CV26-15ZSXE is in Last Buy status.
