It runs at a 100 MHz clock frequency with a 8.5 ns access time, making it suitable for high-bandwidth data buffering in networking, telecom, and FPGA-based designs that need a wide, fast local memory. The 36-bit word width is a distinguishing feature — it maps directly to a 36-bit data bus without needing to gang multiple narrower memories. ## 100-TQFP footprint — board compatibility This limits the part to indoor, climate-controlled environments — office equipment, telecom central office, test instrumentation, and similar.","metaTitle":"CY7C1381C-100AC 18Mbit Synchronous SRAM, 100 MHz, 8.5 ns","metaDescription":"Infineon (Cypress) CY7C1381C-100AC 18Mbit synchronous SRAM, 100 MHz clock, 8.5 ns access time, 512K x 36, 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":"-","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"8.5 ns","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1381","Memory Organization":"512K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/56a3940133edb2b41808b9963161b4a5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1381C-100AC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1381C-100AC?","answer":"For a drop-in alternative, look for other 100-pin TQFP synchronous SRAMs with 512K x 36 organization and a 100 MHz clock — but verify the pinout and timing compatibility against the original datasheet before substituting.
