A cross-reference search against the 100-pin TQFP footprint, 3.3 V supply, and 133 MHz speed grade is the practical next step. The 133 MHz clock rate and 6.5 ns access time define the part's place in a high-speed synchronous memory bus. A 133 MHz clock period is about 7.5 ns, so the 6.5 ns access leaves roughly 1 ns of setup margin before the next rising edge — tight but workable with proper PCB layout (matched trace lengths, controlled impedance, and adequate decoupling on the 3.3 V rail). The NoBL architecture eliminates the dead bus cycle between reads and writes, giving back-to-back throughput at the full clock rate. This matters for applications like packet buffering or cache tag RAM where every cycle counts. ## Package and footprint: 100-TQFP (14x20 mm) It is a surface-mount, RoHS-compatible package (the 'I' suffix indicates industrial temperature and lead-free). The footprint is standard for 100-pin TQFPs of this body size; verify the land pattern against the mechanical drawing in the datasheet.","metaTitle":"Infineon CY7C1371DV33-133AXI NoBL SRAM, 18Mbit, 133 MHz","metaDescription":"Infineon CY7C1371DV33-133AXI NoBL synchronous SRAM, 18Mbit (512K x 36), 133 MHz clock, 6.5 ns access, -40 to 85°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"NoBL™","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"6.5 ns","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1371","Memory Organization":"512K x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$25.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/52dca962383127ca0457a31ad28c800f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1371DV33-133AXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1371DV33-133AXI still available for purchase?","answer":"Yes, it is available to order through independent distribution.
