The NoBL™ (No Bus Latency) architecture eliminates the dead cycle normally required when switching from read to write or write to read, so back-to-back transactions run at full clock rate without a turnaround penalty. That matters in cache-tag, FIFO, and network-buffer applications where every cycle counts. ## Package and supply — what to check on the board No last-time-buy window remains open. Sourcing is limited to the surplus and broker channel, where stock is finite and prices reflect scarcity.","metaTitle":"CY7C1357C-100AXC NoBL™ SRAM, 9Mbit, 100 MHz, 7.5 ns","metaDescription":"Cypress NoBL™ synchronous SRAM, 9 Mbit (512K x 18), 100 MHz clock, 7.5 ns access time.","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":"7.5 ns","Memory Size":"9Mbit","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":"CY7C1357","Memory Organization":"512K x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ed84243fe66837106fd618dc4170b8ee.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1357C-100AXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1357C-100AXC obsolete?","answer":"Yes, the CY7C1357C-100AXC is listed as Obsolete.
