That 16-bit width matches processors with a 16-bit external data bus directly; for 8-bit or 32-bit controllers, two devices can be paired for 32-bit width or byte-lane control is handled by the upper address bits. The 4 Mbit density provides 512 KB of storage, enough for boot code shadowing, packet buffers, or display frame storage in mid-complexity embedded systems. No level translation is needed on the address or data lines when interfacing to a 3.3 V FPGA, ASIC, or MCU memory controller. ## 44-SOJ package — footprint and assembly The 44-SOJ package uses J-leads on a 0.400-inch (10.16 mm) wide body, with a standard 1.27 mm pitch. It is a surface-mount package that reflows with conventional solder profiles. The SOJ footprint is well-established in memory modules and embedded boards; the J-lead form factor provides good coplanarity and visual solder-joint inspection.","metaTitle":"Infineon CY7C1041CV33-15VXC 4Mbit Async SRAM, 15 ns, 44-SOJ","metaDescription":"Infineon CY7C1041CV33-15VXC is a 4Mbit asynchronous SRAM with 15 ns access time, organized 256K x 16, 3V-3.6V supply, 44-SOJ package, 0°C-70°C.","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":"Tube","Technology":"SRAM - Asynchronous","Access Time":"15 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6715","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/373ea2afaf624d619fd4f9f3bb1fbd99.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041CV33-15VXC/alternatives.json"},"ai":{"faq":[{"question":"What is the access time of CY7C1041CV33-15VXC?","answer":"The access time is 15 ns, and the write cycle time for word and page operations is also 15 ns.
