If your design uses a slower bus (e.g., 40 ns or 55 ns cycle), the CY7C025-15AC still works — the faster access just means it waits for the bus, not the other way around. There is no direct pin-compatible replacement listed in the official Cypress product line; the closest functional alternative would be a newer dual-port SRAM with similar density and speed, but the pinout and supply voltage must be verified against the original PCB layout.","metaTitle":"CY7C025-15AC Cypress Dual-Port SRAM, 128 Kbit, 15 ns","metaDescription":"Cypress CY7C025-15AC dual-port asynchronous SRAM, 128 Kbit (8K×16), 15 ns access time, 4.5–5.5 V supply, 100-LQFP.","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":"Bag","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"15 ns","Memory Size":"128Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C025","Memory Organization":"8K x 16","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/24372a262b0fdee4cfbd53405e7a28a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C025-15AC obsolete?","answer":"Yes, the CY7C025-15AC is officially marked Obsolete.
