For a BOM line that cannot be redesigned, the only viable supply path is independent distribution. We source this part on a quoted-to-order basis against an RFQ, confirming availability and current pricing at the time of quote. No factory lead time applies. With a 15 ns access time, this SRAM can serve a 16-bit microcontroller or DSP running at clock speeds up to roughly 33 MHz without wait states, assuming the controller's read cycle time exceeds 15 ns. At higher clock rates, the bus controller must insert wait states or pipeline the access, which reduces throughput. For legacy designs originally validated with a 15 ns part, substituting a slower memory would break the timing closure. ## 64K x 16 organization and 3.3 V supply The 64K x 16 organization provides a 16-bit wide data path in a single chip, matching the native bus width of many 16-bit microcontrollers and digital signal processors. It is also commonly paired with 32-bit processors in a 2-chip configuration for a 32-bit data word. ## Industrial temperature grade and 44-SOJ package The 44-SOJ (Small Outline J-lead) package is a surface-mount footprint that was widely used in the 2000s for memory modules and embedded systems. It is still available in the surplus channel but is not recommended for new PCB layouts due to the limited availability of compatible sockets and the package's obsolescence.","metaTitle":"CY7C1021BNV33L-15VXI SRAM, 1 Mbit, 15 ns, 44-SOJ","metaDescription":"Infineon (Cypress) CY7C1021BNV33L-15VXI asynchronous SRAM, 64K x 16, 15 ns access, 3.0-3.6 V, -40 to 85°C, 44-SOJ.","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":"Tube","Technology":"SRAM - Asynchronous","Access Time":"15 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-BSOJ (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-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b52313df5d733a20a081352c1eb65721.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BNV33L-15VXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021BNV33L-15VXI obsolete?","answer":"Yes, Infineon lists this part as obsolete.
