Dual-port architecture means two independent devices (or a processor and an FPGA) can read and write the same memory array simultaneously, with arbitration logic handling contention. The parallel interface keeps the bus simple — no serial protocol overhead — but ties up more PCB traces than a serial SRAM. Housed in a 52-BQFP (10x10 mm 52-PQFP) surface-mount package. The 0.65 mm pitch BQFP footprint is a standard fine-pitch QFP — no exotic soldering process needed, but the fine leads are sensitive to board flex and require careful handling during rework.","metaTitle":"Infineon CY7C131-55NXCT SRAM, 8Kbit, 55ns, 52-BQFP","metaDescription":"Obsolete Infineon CY7C131-55NXCT 8Kbit dual-port asynchronous SRAM, 55ns access time, 4.5-5.5V, 52-BQFP.","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":"Tape & Reel (TR)","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/CY7C131-55NXCT/alternatives.json"},"ai":{"faq":[{"question":"How do I get pricing and availability for CY7C131-55NXCT?","answer":"Submit an RFQ against your BOM quantity.
