It provides two independent ports with separate address, data, and control lines, allowing two bus masters (e.g., a DSP and an MCU, or two processors) to access the same memory array without arbitration logic. The 15 ns access time keeps bus turnaround tight for 5 V legacy systems. Typical applications include shared-memory buffers in telecom line cards, industrial controllers, and multiprocessor systems where a small, fast scratchpad is needed. ## 15 ns access time — timing margin in a 5 V bus In a 5 V system with a 20–25 MHz bus, that leaves roughly 10–15 ns of margin after accounting for PCB trace delay and output loading — comfortable for a single load, but worth verifying if the bus fans out to multiple memories or peripherals. ## 52-PLCC footprint and commercial temperature range Housed in a 52-lead PLCC with J-leads, the package measures 19.13 x 19.13 mm and is surface-mount soldered. The J-lead form factor is socket-friendly for prototyping but requires a PLCC footprint on the PCB — not pin-compatible with SOJ or TSOP. Cypress (now Infineon) no longer manufactures this exact order code. No direct Infineon replacement has been identified for this specific dual-port 8Kbit 52-PLCC variant; verify pin-compatible alternatives in the CY7C131 family if a second source is needed.","metaTitle":"CY7C131-15JXCT Dual-Port SRAM, 8Kbit, 15 ns, 52-PLCC","metaDescription":"Infineon (Cypress) CY7C131-15JXCT is an 8Kbit dual-port asynchronous SRAM with 15 ns access time.","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":"15 ns","Memory Size":"8Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"52-LCC (J-Lead)","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-PLCC (19.13x19.13)","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/04f9ce00d009b85ebfbbc776e498624c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement for CY7C131-15JXCT?","answer":"No direct Infineon replacement has been identified for this specific 8Kbit dual-port asynchronous SRAM in the 52-PLCC package.
