In a system with a 100 MHz bus, that leaves roughly 10 ns for the memory to respond before the next clock edge — tight but workable with careful PCB trace length matching. For existing BOM lines, procurement will need to source through independent distribution or consider a pin-compatible alternative in the same family. Both share the same die and timing, so the -10ZSXI can serve as a drop-in replacement for hand-assembly or smaller quantities, though the reel variant is preferred for automated pick-and-place. The 44-TSOP II (0.400\" body width, 10.16 mm) is a common SRAM footprint. If your existing board uses the -10ZSXI (tube/tray), the -10ZSXAT will reflow identically — the only difference is the shipping medium.","metaTitle":"Infineon CY7C1021DV33-10ZSXAT 1Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1021DV33-10ZSXAT 1Mbit asynchronous SRAM, 64K x 16, 10 ns access time, 3V-3.6V, -40°C 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":"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":"44-TSOP (0.400\\\", 10.16mm Width)","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":"44-TSOP II","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6f2b95d776e36f1bbd5c05a2da5dbdad.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1021DV33-10ZSXAT?","answer":"There is no official successor listed.
