This is not a single-port memory — the dual-port architecture gives two independent bus masters simultaneous read/write access to the same array, with on-chip arbitration logic handling address conflicts. Typical applications include shared memory between two processors in a multiprocessor system, buffering between a DSP and an FPGA, or a mailbox register in a redundant controller pair. ## 20 ns access — bus margin for a 50 MHz master The 20 ns access time and 20 ns write cycle time are specified in the datasheet. The parallel interface uses address, data, and dual-port control signals including chip selects, read/write enables, and a BUSY flag for collision detection. ## Active lifecycle — no last-time-buy pressure For a BOM that needs a proven dual-port SRAM for a multi-year production run, this part does not carry the supply risk of a phase-out line. It is ROHS3 compliant, so it passes the EU material restrictions without an exemption.","metaTitle":"70V05L20PFGI Dual-Port SRAM, 64Kbit, 20 ns, 64-TQFP","metaDescription":"Renesas 70V05L20PFGI 64Kbit dual-port asynchronous SRAM, 20 ns access time, 8K x 8 organization, 3.0–3.6 V, -40°C to 85°C, 64-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tray","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"20 ns","Memory Size":"64Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"64-LQFP","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Memory Organization":"8K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-TQFP (14x14)","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$44.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$44.97000","currency":"USD"},{"qty":10,"price":"$41.71100","currency":"USD"},{"qty":24,"price":"$40.22167","currency":"USD"},{"qty":45,"price":"$39.22000","currency":"USD"},{"qty":90,"price":"$34.36556","currency":"USD"},{"qty":270,"price":"$33.41526","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0931c5bd2edf25a5644c9ca195d82aca.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source to 70V05L20PFGI?","answer":"The 71V124SA12TYGI is a larger dual-port SRAM (1Mbit, 128K x 8) with a faster 12 ns access time, but it runs on a 3.0 V supply and ships in a tube package rather than a tray.
