Its dual-port architecture allows two independent buses to read from or write to the same memory array simultaneously, eliminating the need for external arbitration logic in shared-memory designs. ## 15 ns access time — arbitration latency in dual-port designs In a dual-port SRAM, this spec directly affects the arbitration overhead when both ports contend for the same memory location. A 15 ns window means the part can keep up with moderate-speed processors without inserting wait states, provided the arbitration logic resolves contention within the same cycle. ## 52-PLCC footprint and rework considerations The 52-PLCC package with J-leads (body 19.13 x 19.13 mm) is a legacy surface-mount form factor. The J-lead geometry requires a specific hot-air rework profile — the leads are hidden under the package body, so a standard gull-wing nozzle will not reach. Preheating the board before removal reduces the risk of pad lift. If the end system sees ambient temperatures below freezing or above 70°C, a different dual-port SRAM with an industrial or military temperature grade is required.","metaTitle":"CY7C131-15JC Cypress 8Kbit Dual-Port SRAM, 15 ns, 52-PLCC","metaDescription":"Cypress CY7C131-15JC obsolete 8Kbit dual-port asynchronous SRAM, 15 ns access time, 1K x 8, 4.5–5.5 V, 0°C–70°C, 52-PLCC.","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":"Tube","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/5e48d5d1639fa3e2218458e8b2f4315c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C131-15JC compatible with 5V logic?","answer":"The 15 ns access time is specified at the nominal 5 V supply."},{"question":"Can CY7C131-15JC be used in new designs?","answer":"It is not recommended for new designs because the part is obsolete.
