In a dual-port arbitration scenario, the bus-turnaround overhead and the 25 ns write cycle time (word, page) mean the part can sustain back-to-back accesses at roughly 40 MHz if the arbitration logic is fast enough. For a system architect, this is the speed tier that fits 8- or 16-bit buses running at 20–33 MHz; pushing beyond that requires a faster grade or a synchronous dual-port part.","metaTitle":"CY7C131-25NXC Cypress 8Kbit Dual-Port SRAM, 25 ns, Obsolete","metaDescription":"Cypress CY7C131-25NXC 8Kbit (1K x 8) dual-port asynchronous SRAM, 25 ns access time, 5V supply, 52-PQFP, 0°C to 70°C.","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 - Dual Port, Asynchronous","Access Time":"25 ns","Memory Size":"8Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"52-BQFP","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C131","Memory Organization":"1K x 8","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"52-PQFP (10x10)","Write Cycle Time - Word, Page":"25ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fddcec30d8718da2846811f345189234.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C131-25NXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C131-25NXC?","answer":"For a pin-compatible alternative, review the Cypress dual-port SRAM family with the same 52-PQFP footprint and 5V supply; parametric differences (access time, density) must be verified against the target bus timing and memory depth."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C131-25NXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C131-25NXC when reusing this data.
