It is a single-data-rate (SDR) pipeline-burst device designed for cache and buffering in networking, telecom, and embedded systems that need deterministic read/write latency. The 100 MHz clock and 8 ns access time keep the bus cycle tight for a mid-speed synchronous memory. ## 8 ns access time at 100 MHz — timing budget for the bus With a 100 MHz clock, the 8 ns access time leaves margin for the controller. The synchronous pipeline means the part latches the address on the rising edge and presents data on the next cycle. The CY7C1353F-100AC is marked obsolete by Infineon. There is no listed successor in the record, so anyone holding a BOM with this line item is looking at the surplus and broker channel.","metaTitle":"Infineon CY7C1353F-100AC SRAM, 4.5Mbit, 8 ns, 100 MHz","metaDescription":"Infineon CY7C1353F-100AC synchronous SRAM, 4.5Mbit (256K x 18), 8 ns access time, 100 MHz clock, 100-LQFP.","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 ns","Memory Size":"4.5Mbit","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":"CY7C1353","Memory Organization":"256K 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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e2bafcdddae4c80869685ac62696e0c4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of CY7C1353F-100AC?","answer":"The access time is 8 ns, which at a 100 MHz clock leaves about 2 ns of bus margin for the controller."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1353F-100AC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1353F-100AC when reusing this data.
