Infineon lists this part as obsolete. That means no new factory orders are accepted — the only channel is surplus and independent distribution. If this SRAM is on a current BOM, the procurement decision is straightforward: buy the remaining lifetime volume now, or qualify a pin-compatible alternative before the surplus stock dries up. The 10 ns access time and 64K x 16 organization are common enough that a drop-in replacement from another vendor (e.g., ISSI, Alliance Memory) may exist, but the 48-TFBGA footprint narrows the field — verify the ball map against the replacement before committing a board spin.","metaTitle":"Infineon CY7C1021CV33-10BAXIT 1Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1021CV33-10BAXIT 1Mbit asynchronous SRAM, 10 ns access time, 64K x 16 organization, 3V-3.6V supply, industrial temp.","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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"48-TFBGA","Product Status":"Obsolete","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 ~ 85°C (TA)","Supplier Device Package":"48-FBGA (7x7)","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8de780a0263d3c8d238b651a92bb2a7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C1021CV33-10BAXIT?","answer":"Infineon does not list an official successor for this part. Several vendors (ISSI, Alliance Memory, Renesas) offer 1Mbit asynchronous SRAMs with 10 ns access time in 48-TFBGA, but the ball-out and supply voltage range must be cross-checked. The CY7C1021CV33-10BAXIT uses a 3V–3.6V supply and 64K x 16 organization — any replacement must match those parameters and the 48-ball footprint."},{"question":"What compliance documentation does this brand provide for CY7C1021CV33-10BAXIT?","answer":"Infineon provides RoHS and REACH compliance documentation for this part.
