No socket exists for prototyping — first-article boards need the BGA placed. The supplier device package is 119-PBGA, and the mounting type is surface mount. For a repair technician: this is not a hand-solderable part; a failed SRAM means board-level rework with a BGA station or scrapping the board. ## Lifecycle and sourcing posture That means it can be specified into new designs without an immediate end-of-life risk. No official second-source or pin-compatible replacement is listed in the Renesas documentation, so dual-sourcing would require a functionally equivalent part from another vendor with careful timing and package comparison.","metaTitle":"71V3557S75BG SRAM 4.5Mbit, 7.5 ns, 119-BGA","metaDescription":"71V3557S75BG synchronous ZBT SRAM, 4.5 Mbit (128K x 36), 7.5 ns access time, 119-PBGA, 3.3 V supply, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Bulk","Technology":"SRAM - Synchronous, SDR (ZBT)","Access Time":"7.5 ns","Memory Size":"4.5Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"119-BGA","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.465V","Memory Organization":"128K x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"119-PBGA (14x22)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.46","stockQuantity":0,"priceTiers":[{"qty":55,"price":"$5.46000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ad81e702c2caad943145dee70b84abbb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time and memory organization of 71V3557S75BG?","answer":"Access time is 7.5 ns, and the memory is organized as 128K x 36 bits (4.5 Mbit total)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/71V3557S75BG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/71V3557S75BG when reusing this data.
