The commercial temperature range (0°C to 70°C) limits it to indoor, controlled-environment equipment. ## 44-SOJ package — board integration note Housed in a 44-SOJ (Small Outline J-lead) package with a 0.400-inch (10.16 mm) body width, the part is surface-mount but uses J-bend leads that require a specific solder paste stencil aperture — the lead footprint is wider than a standard SOIC, so a legacy board layout may already have the correct pad geometry. Supplied in tube packaging, the SRAM is suitable for hand-assembly or low-volume reflow. The J-lead form factor provides good coplanarity and visual solder-joint inspection access, which is helpful for rework in repair or prototyping scenarios.","metaTitle":"Infineon CY7C1021BNV33L-15VXC 1Mbit Async SRAM, 15ns","metaDescription":"Infineon CY7C1021BNV33L-15VXC asynchronous SRAM, 1 Mbit (64K x 16), 15 ns access, 3V-3.6V, 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":"0°C ~ 70°C (TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/10330d3e23287666913c318fd4ab1a47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C1021BNV33L-15VXC?","answer":"This part is sourced through independent distribution channels.
