The write cycle time matches the access time at 15 ns, so back-to-back writes complete in a single bus cycle on a 33 MHz master.","metaTitle":"CY7C1021BNL-15ZSXA Infineon 1Mbit Async SRAM, 15 ns","metaDescription":"Infineon (Cypress) CY7C1021BNL-15ZSXA 1Mbit asynchronous SRAM, 64K x 16, 15 ns access, 4.5-5.5V, -40 to 85°C, 44-TSOP II.","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":"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":"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":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5656","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b005a36e8e3c18743572ba4643b8046f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BNL-15ZSXA/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021BNL-15ZSXA obsolete?","answer":"Yes, the CY7C1021BNL-15ZSXA is marked Obsolete by Infineon. There is no official replacement listed in the record. For ongoing production, you will need to source from the independent surplus channel or qualify a pin-compatible alternative with matching 15 ns access time and 64K x 16 organization."},{"question":"What is the replacement for CY7C1021BNL-15ZSXA?","answer":"No official replacement is recorded.
