The package is a 36-pin SOJ (Small Outline J-lead), surface-mount, with a body width of 10.16 mm (0.400\"). J-leads are more robust than gull-wing for manual rework — the leads tuck under the body, so there's less risk of lifting a pad when you hit it with hot air. No further factory orders are being accepted, and no last-time-buy window remains open. If this part is on your BOM, you are now in the surplus-and-broker channel for any future procurement. There is no official Cypress successor listed for this exact order code. For a legacy board that cannot be redesigned, the practical path is to source from independent distribution. Expect to work with date-code mixes; the 17 ns speed grade and 5V supply are the two parameters that must match to keep the bus timing intact. Write cycle time is also 17 ns. The 512K x 8 organization means the data bus is 8 bits wide.","metaTitle":"CY7C1049B-17VC Cypress 4Mbit Async SRAM, 17 ns, 36-SOJ","metaDescription":"CY7C1049B-17VC Cypress 4Mbit asynchronous SRAM, 512K x 8, 17 ns access time, 4.5V-5.5V, 0°C to 70°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":"17 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":"4.5V ~ 5.5V","Base Product Number":"CY7C1049","Memory Organization":"512K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"36-SOJ","Write Cycle Time - Word, Page":"17ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3998","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/05c20756d39318a5cb450a58f26b9eb2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049B-17VC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1049B-17VC obsolete?","answer":"Yes, Cypress has classified the CY7C1049B-17VC as Obsolete.
