This is the spec that determines whether the part keeps up with a cacheless ARM7 or a CPLD-based state machine without wait states. Cypress (now Infineon) no longer manufactures this part. No LTB window remains; the part is what it is on the open market. The J-lead form factor is a legacy SOIC variant with a smaller footprint than DIP but still hand-solderable with care. Supply range of 3V to 3.6V aligns with 3.3V logic families; no level translation needed for a 3.3V bus.","metaTitle":"Cypress CY7C1049CV33-10VXA 4Mbit Async SRAM, 10 ns","metaDescription":"Cypress CY7C1049CV33-10VXA 4Mbit asynchronous SRAM, 512K x 8 organization, 10 ns access time, 3V-3.6V supply, -40°C to 85°C, 36-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":"10 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"36-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1049","Memory Organization":"512K x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"36-SOJ","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/21ee4ab087c9aeda792a0fd4564f6526.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049CV33-10VXA/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1049CV33-10VXA obsolete?","answer":"Yes, the CY7C1049CV33-10VXA is listed as Obsolete.
