It comes in a 36-SOJ surface-mount package, a legacy but still widely supported footprint for through-hole-alternative SRAM on multilayer boards. ## 10 ns access time — timing budget for the bus The 10 ns access time and equal 10 ns write cycle time are the headline ratings for this SRAM. For a system architect, that 10 ns window defines how much of the bus cycle is consumed by the memory itself. With a 100 MHz bus clock (10 ns period), the SRAM consumes the entire cycle if the controller's address-to-output propagation is tight. In practice, a 66 MHz or 80 MHz bus leaves enough margin for PCB trace delays and output hold. The 512K x 8 organization means byte-wide access — useful for 8-bit MCUs or as a data buffer in a 32-bit system where four chips are banked. The parallel interface is straightforward to wire, but the 36-SOJ footprint needs a land pattern that matches the 0.400-inch body width. No PCN bulletins have flagged this specific order code for end-of-life. The base product number CY7C1049 covers the whole family, so if a different speed or package variant is needed later, the same design rules apply.","metaTitle":"Infineon CY7C1049GN30-10VXIT SRAM, 4 Mbit, 10 ns, 36-SOJ","metaDescription":"Infineon CY7C1049GN30-10VXIT is a 4 Mbit asynchronous SRAM with 10 ns access time, 512K x 8 organization, parallel interface, 2.2V to 3.6V supply, -40°C to","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) 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":"2.2V ~ 3.6V","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":null},"links":{"datasheetUrl":"https://cdn.icboms.com/16926ab39af6da3a7b9733ac52c7a8c8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049GN30-10VXIT/alternatives.json"},"ai":{"faq":[{"question":"What is the access time of CY7C1049GN30-10VXIT?","answer":"This makes the part suitable for bus speeds up to 100 MHz with careful timing closure, and a comfortable fit at 66 MHz to 80 MHz with margin for PCB delays."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1049GN30-10VXIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1049GN30-10VXIT when reusing this data.
