The NoBL™ architecture eliminates the dead bus cycle between read and write turns, so back-to-back transactions run at full clock rate — useful in networking buffers, DSP memory pools, and FPGA co-processing where every cycle counts. ## 6.5 ns access time — timing margin for the system designer At a 133 MHz clock (7.5 ns period), that leaves about 1 ns of margin before the next clock edge — tight but workable with controlled PCB impedance and matched trace lengths. If your FPGA or ASIC has a setup time of 1.5 ns, you are inside the window; if the controller is slower, you may need to add a wait state or drop to a lower clock rate. The 133 MHz clock frequency is the maximum rated speed; the part will run slower if the system clock is divided down, but the access time stays at 6.5 ns regardless of the actual clock rate. It is not rated for industrial motor drives, outdoor base stations, or automotive under-hood environments.","metaTitle":"CY7C1371KV33-133AXC SRAM, 18Mbit, 133MHz, 6.5ns, 100-LQFP","metaDescription":"Cypress CY7C1371KV33-133AXC 18Mbit synchronous SRAM, 133MHz clock, 6.5ns access time, 512Kx36, 3.135-3.6V, 0-70°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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":"Active","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":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$30.9750","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/859454d91243e0f63fa69b45c819ba95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1371KV33-133AXC/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between CY7C1371KV33-133AXC and CY7C1371KV33-133BXC?","answer":"Both share the same 133 MHz clock, 6.5 ns access time, 18 Mbit density, and 100-LQFP package.
