That means the manufacturer has a final purchase window open, after which this exact order code will no longer be produced. For sustainment programs — medical, defense, industrial controls — this is the trigger to either place a lifetime buy or qualify a form-fit-function alternative. Access time is 12 ns. Write cycle time also 12 ns. The 125°C ceiling covers the junction temperature in a sealed enclosure with limited airflow. If your design stays in a conditioned lab or office, the commercial-grade sibling would save cost, but for field-deployed hardware this temperature range is the right call. ## Supply and package — 3V–3.6V in 44-TSOP II The 44-TSOP II package is surface mount.","metaTitle":"CY7C1021CV33-12ZSXE SRAM, 1 Mbit, 12 ns, 44-TSOP II","metaDescription":"Infineon CY7C1021CV33-12ZSXE asynchronous SRAM, 1 Mbit (64K x 16), 12 ns access time, 3V–3.6V, -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":"12 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":"3V ~ 3.6V","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":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3e54e17eda19778b9d1667b1edb16a21.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021CV33-12ZSXE/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021CV33-12ZSXE obsolete or in last time buy?","answer":"Yes, Infineon has marked this part as Last Buy.
