It runs at a 150 MHz clock with a 3.8 ns access time, feeding a parallel interface that eliminates the dead bus cycle between read and write operations. This makes it a natural fit for high-throughput datapaths in networking equipment, baseband processing, and DSP arrays where every clock cycle of bus utilization counts. The commercial temperature range (0°C to 70°C) confines it to controlled indoor environments — server rooms, telecom central offices, test equipment — not unheated enclosures or outdoor cabinets. ## 3.8 ns access time at 150 MHz – timing margin in practice The 3.8 ns access time is the delay from address assertion to data valid on the bus. At a 150 MHz clock, that leaves margin for the receiving FPGA or ASIC. ## Lifecycle and sourcing posture The 71V65603S150PFG carries an Active lifecycle status. For production BOM lines, this means no near-term obsolescence risk. The package marking and date-code consistency should be verified on receipt — the 100-TQFP form factor is a known target for re-marking in the gray market, so lot traceability back to the authorized channel is worth documenting.","metaTitle":"71V65603S150PFG 9Mbit ZBT SRAM, 150 MHz, 3.8 ns, 100-TQFP","metaDescription":"71V65603S150PFG is a 9Mbit synchronous SRAM with ZBT technology, 150 MHz clock, 3.8 ns access time, 256K x 36 organization, 3.135V–3.465V supply, 0°C–70°C","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":"3.8 ns","Memory Size":"9Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Clock Frequency":"150 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.465V","Memory Organization":"256K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x14)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.68","stockQuantity":0,"priceTiers":[{"qty":29,"price":"$10.68000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/327dbdaa59bdc067f1a280bb5884ef85.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does 71V65603S150PFG support ZBT (Zero Bus Turnaround) mode?","answer":"Yes, the part uses Synchronous SDR (ZBT) technology, which eliminates the dead bus cycle between read and write operations for continuous throughput."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/71V65603S150PFG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/71V65603S150PFG when reusing this data.
