The ball pitch and layout demand careful decoupling placement — the 1.7 V–1.9 V core rail is tight, and the 400 MHz clock edge needs low-inductance bypass capacitors within 2 mm of the BGA pads.","metaTitle":"CY7C1543KV18-400BZC QDR II+ SRAM, 72 Mbit, 400 MHz, Obsolete","metaDescription":"Cypress CY7C1543KV18-400BZC is a 72 Mbit QDR II+ synchronous SRAM in 165-FBGA, 400 MHz clock.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1543","Memory Organization":"4M x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$201.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b39f5a64178bda89935882d8448a00c2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1543KV18-400BZC/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1543KV18-400BZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1543KV18-400BZC when reusing this data.
