It clocks at 133 MHz with a 4.2 ns access time. Supply range is 3.135 V to 3.465 V. The industrial temperature grade is -40°C to 85°C. ## Package and footprint — what the 100-TQFP demands The part ships in a 100-lead LQFP (also specified as 100-TQFP) with a 14x14 mm body. ## Lifecycle and sourcing reality For a BOM line that needs a synchronous SRAM at this density and speed grade, there's no LTB clock ticking.","metaTitle":"71V3558S133PFGI 4.5Mbit Synchronous SRAM, 133 MHz, 4.2 ns","metaDescription":"71V3558S133PFGI 4.5Mbit (256K x 18) synchronous SRAM with 4.2 ns access time, 133 MHz clock, industrial temp -40 to 85°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Bulk","Technology":"SRAM - Synchronous, SDR (ZBT)","Access Time":"4.2 ns","Memory Size":"4.5Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.465V","Memory Organization":"256K x 18","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-TQFP (14x14)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.93","stockQuantity":0,"priceTiers":[{"qty":51,"price":"$5.93000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f215e63550592a192ce1bb04318c59ff.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of the 71V3558S133PFGI?","answer":"The access time is 4.2 ns.
