In a system with a 66 MHz or slower controller, this gives comfortable setup-and-hold margin without wait states. The write cycle time matches the access time at 15 ns, so back-to-back read-write sequences run at the same speed. ## 2.5V to 2.7V supply — a narrow window to budget The supply range of 2.5V to 2.7V is tighter than the more common 2.7V to 3.6V or 3.0V to 3.6V found on many 3.3V-logic SRAMs. A 2.5V rail must stay within 200 mV of nominal; a 2.7V rail is the absolute maximum. If your board already runs a 2.5V supply, this part fits directly. If you are stepping down from 3.3V, a dedicated LDO or regulator with tight tolerance is required. The extended temperature range covers both cold-start at -40°C and continuous operation at 125°C ambient. The 44-SOJ package with its J-bend leads handles the thermal cycling without solder-joint fatigue seen in some gull-wing packages. Sourcing is limited to independent distribution — new-old-stock or surplus inventory held by brokers and specialty suppliers. Any remaining stock is finite, and once depleted, no further production runs are planned.","metaTitle":"Infineon CY7C1021CV26-15VXET SRAM, 1Mbit 15ns 44-SOJ","metaDescription":"Infineon CY7C1021CV26-15VXET asynchronous SRAM, 1Mbit (64K x 16), 15ns access, 2.5V-2.7V, -40°C to 125°C, 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":"15 ns","Memory Size":"1Mbit","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":"2.5V ~ 2.7V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/12270f7709a339868cfd2e499436aa36.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1021CV26-15VXET?","answer":"No official replacement has been recorded. For a pin-compatible alternative, look at other 1Mbit (64K x 16) async SRAMs in a 44-SOJ package with a 2.5V to 2.7V supply range and 15 ns or faster access time.
