The 20 ns access time means a read or write completes in one fast cycle at typical 50 MHz bus speeds, so neither port stalls the other. Supply runs from 3V to 3.6V, making it a fit for 3.3 V logic families common in mid-2000s embedded designs. The 100-TQFP (14x14) package is the surface-mount footprint for that generation of shared-memory applications. ## Obsolete — plan for surplus or replacement now Infineon lists the CY7C025AV-20AC as obsolete. For new production or repair, the only channel is independent distribution — surplus inventory, new-old-stock, or broker-sourced lots. If you are qualifying a BOM line, verify the 100-TQFP footprint and 20 ns timing against any candidate replacement; a same-function dual-port SRAM from a different vendor may require a timing or supply-voltage adjustment. At a 50 MHz bus clock (20 ns period), a single wait-state gives the memory a full cycle to respond; with a 0-wait controller the 20 ns part must meet the setup time at the receiving flip-flop, which usually closes timing. If your system runs a slower bus (say 25 MHz or below), the 20 ns part provides comfortable margin; if you are pushing toward 66 MHz, you would need a 12 ns or 10 ns dual-port SRAM.","metaTitle":"Infineon CY7C025AV-20AC Dual-Port SRAM, 128Kbit, 20 ns","metaDescription":"Infineon CY7C025AV-20AC is an obsolete 128Kbit asynchronous dual-port SRAM with 20 ns access time, 3V–3.6V supply, in a 100-TQFP.","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":"20 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":"3V ~ 3.6V","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":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a3b4c2fc69bfc5618525b86877ed3829.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C025AV-20AC?","answer":"No official replacement order code is listed by Infineon.
