Operating temperature is 0°C to 70°C. ## Package and mounting Housed in a 100-LQFP (supplier device package 100-TQFP, 14x14 mm body). ## Lifecycle and sourcing The 71V3578S150PFG carries an active lifecycle status — no last-time-buy notice, no end-of-life risk on the immediate horizon. It remains a current-production part, which simplifies BOM planning for new designs and avoids the premium pricing that obsolete synchronous SRAMs often command on the surplus market. For a BOM freeze or a production ramp, this part can be qualified into the supply chain without the clock ticking on availability.","metaTitle":"71V3578S150PFG 4.5Mbit Sync SRAM, 150 MHz, 3.8 ns Access","metaDescription":"71V3578S150PFG synchronous SRAM: 4.5 Mbit (256Kx18), 150 MHz clock, 3.8 ns access, 3.3V supply, 100-TQFP.

At a 150 MHz clock (6.67 ns period), this leaves roughly 2.9 ns of timing margin for the receiving logic after the data becomes valid — a figure that needs careful PCB trace-length matching and signal-integrity analysis to close timing."},{"question":"What voltage does the 71V3578S150PFG use?","answer":"The supply voltage range is 3.135 V to 3.465 V — a standard 3.3 V rail with ±5 % tolerance. The system's 3.3 V supply must stay within this window at the device pins, accounting for IR drop across the PCB."},{"question":"What is the memory organization of 71V3578S150PFG?","answer":"Organized as 256K words by 18 bits, for a total of 4.5 Mbit. The x18 width is useful for 16-bit data with two parity bits, or for DSP systems that process 18-bit fixed-point words natively."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/71V3578S150PFG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/71V3578S150PFG when reusing this data.
