The 10 ns cycle time keeps bus turnaround tight for processors running at moderate clock rates — no wait states needed on a 50 MHz bus, for example. The 10 ns access time matches the write cycle time of 10 ns, meaning read and write latencies are symmetric. For a memory-mapped peripheral or a cache tag store, that symmetry simplifies timing closure — you don't need separate margin budgets for read vs write. At 3.3 V nominal the chip delivers this across the full industrial temperature range, not just at 25°C. If your system runs from a 2.2 V rail, expect the access time to stretch; the datasheet's derating curves (not reproduced here) should be checked against your worst-case supply. ## Package and assembly Housed in a 44-TSOP II (0.400\", 10.16 mm width) package, surface-mount only. The Tape & Reel (TR) delivery suits automated pick-and-place lines. Standard MSL for this package family is typically 3 — verify the moisture sensitivity level on the reel label before reflow. The 44-TSOP II footprint is shared across several density options in the CY7C1049 family, so a board layout can be reused if a smaller or larger density is needed later.","metaTitle":"Infineon CY7C1049GE30-10ZSXIT 4Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1049GE30-10ZSXIT asynchronous SRAM, 4Mbit (512K x 8), 10 ns access time, 2.2V–3.6V, industrial temp -40°C to 85°C, 44-TSOP II.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"2.2V ~ 3.6V","Base Product Number":"CY7C1049","Memory Organization":"512K x 8","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":"$5.2279","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0de5f26f3dc2855e05f784407037fc59.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049GE30-10ZSXIT/alternatives.json"},"ai":{"faq":[{"question":"What is the access time of CY7C1049GE30-10ZSXIT?","answer":"This is a synchronous-free, parallel-interface SRAM, so the access time directly sets the minimum cycle time for back-to-back operations."},{"question":"What is the memory organization of CY7C1049GE30-10ZSXIT?","answer":"Organized as 512K words by 8 bits (512K x 8), for a total of 4 Mbit."},{"question":"What package does CY7C1049GE30-10ZSXIT come in?","answer":"It is supplied in a 44-TSOP II package (0.400\" body width, 10.16 mm), surface-mount, on Tape & Reel.
