Its 15 ns access time and 15 ns write cycle time are the key timing parameters. ## 5 V supply and 44-SOJ footprint — design-in constraints If your board uses a 3.3 V or 1.8 V core, you will need a level translator on the address/data lines — or pick a 3.3 V SRAM in the same family. The 44-SOJ package (JEDEC MO-119, 400 mil body width) is a surface-mount, J-lead outline that takes up about 10.16 mm x 27.94 mm of board area. It is not pin-compatible with the wider 44-pin TSOP-II (400 mil) used by many 8 Mbit and larger SRAMs, so a board respin is required if you are migrating from a different footprint. Infineon lists the CY7C1021BNL-15VXC as Obsolete.","metaTitle":"Infineon CY7C1021BNL-15VXC 1Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C1021BNL-15VXC 1Mbit asynchronous SRAM, 15 ns access time, 64K x 16, 4.5V-5.5V, 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":"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":"4.5V ~ 5.5V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9974","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b005a36e8e3c18743572ba4643b8046f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BNL-15VXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1021BNL-15VXC?","answer":"Infineon does not list an official successor for the CY7C1021BNL-15VXC.
