If your design needs 16-bit word access, you would pair two of these or look at the 256K x 16 sibling CY7C1041G-10ZSXIT. The parallel interface is straightforward — address, data, chip enable, output enable, write enable — no clocked handshake, no refresh cycle to manage. ## 36-SOJ package — reflow and footprint notes The 36-SOJ package (36-pin Small Outline J-lead, 10.16 mm body width) is a surface-mount form factor with J-bend leads tucked under the body. The J-bend also makes visual inspection of the solder joint harder; if your AOI system is set up for gull-wing only, you may need to adjust the inspection algorithm or add an X-ray spot-check. It is ROHS3 compliant. For dual-sourcing flexibility, the CY7C1049G30-10VXIT is a functional equivalent with the same 4 Mbit density and 10 ns access time, but operates at 2.2 V supply — verify your 5 V rail can tolerate the lower voltage before substituting.","metaTitle":"Infineon CY7C1049GN-10VXIT 4Mbit Async SRAM, 10 ns, 5 V","metaDescription":"Infineon CY7C1049GN-10VXIT 4Mbit asynchronous SRAM, 512K x 8, 10 ns access time, 4.5 V to 5.5 V supply, -40°C to 85°C, 36-SOJ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","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":"Active","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","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":"$7.0800","priceTiers":[{"qty":1,"price":"$7.08000","currency":"USD"},{"qty":10,"price":"$6.51100","currency":"USD"},{"qty":25,"price":"$6.37560","currency":"USD"},{"qty":50,"price":"$6.35360","currency":"USD"},{"qty":100,"price":"$5.70110","currency":"USD"},{"qty":250,"price":"$5.52880","currency":"USD"},{"qty":500,"price":"$5.25748","currency":"USD"},{"qty":1000,"price":"$5.07416","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/16926ab39af6da3a7b9733ac52c7a8c8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049GN-10VXIT/alternatives.json"},"ai":{"faq":[{"question":"What is the access time of CY7C1049GN-10VXIT?","answer":"The access time is 10 ns for both read and write cycles.
