Its 25 ns access time and 25 ns write cycle time allow it to keep pace with legacy 5V CPLDs, microcontrollers, and DSPs running at moderate clock rates, making it a fit for shared-buffer applications in telecom line cards, industrial controllers, and multiprocessor systems. For a system with a 40 MHz bus clock (25 ns period), this part leaves zero margin for address-to-data setup — the bus must be clocked slower or the memory controller must insert a wait state. It pairs cleanly with 20 MHz or slower buses where the full access fits within one cycle. This simplifies the memory controller design because you do not need separate timing parameters for read versus write cycles. ## 5V supply and commercial temperature — fit check If your board runs a 5V rail, this part connects directly without level shifters. Do not use it on a 3.3V-only bus — the supply minimum is 4.5V. There is no factory lead time to reference. ## Package and footprint — 52-PLCC The J-lead form factor is surface-mount but requires a PLCC socket or a reflow profile compatible with J-lead solder joints. The shipping medium is Tube.","metaTitle":"CY7C131-25JC Dual-Port SRAM, 25 ns, 8Kbit, Obsolete","metaDescription":"Infineon (Cypress) CY7C131-25JC 8Kbit dual-port asynchronous SRAM with 25 ns access time, 5V supply, 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":"25 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":"25ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ea63cfe7a1b5355a95e28fd40fb8fe78.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C131-25JC obsolete?","answer":"Yes, the CY7C131-25JC is officially marked as obsolete by the manufacturer.
