It is designed for systems that need two independent buses to read from or write to the same memory array without arbitration overhead — typically shared memory in multiprocessor or DSP systems, FIFO emulation, or register-file applications. ## Package and footprint — 52-pin QFP The CY7C131-55NXC is supplied in a 52-BQFP package, also described as a 52-PQFP with a 10x10 mm body. It is a surface-mount gull-wing quad flat pack. The footprint is a standard 52-pin QFP with 0.65 mm pitch. For rework or replacement, the same package footprint is shared by several other Cypress dual-port SRAM densities, but the supply voltage and timing must be verified.","metaTitle":"Cypress CY7C131-55NXC 8Kbit Dual-Port SRAM, 55 ns","metaDescription":"Cypress CY7C131-55NXC 8Kbit asynchronous dual-port SRAM, 55 ns access time, 1K x 8 organization, 52-PQFP, 4.5V-5.5V supply, 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":"55 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":"55ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4525bc76605bfaec121d3b7d6a8f362d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C131-55NXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C131-55NXC?","answer":"A functionally equivalent dual-port SRAM with 55 ns access time, 5V supply, and 52-pin QFP footprint would need to be validated for pin-compatibility and timing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C131-55NXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C131-55NXC when reusing this data.
