It allows two independent systems or processors to read from and write to the same memory array simultaneously, with separate address, data, and control buses on each port. This eliminates bus contention and external arbitration logic in applications like shared memory, multiprocessor buffers, and telecom line cards where two controllers need access to a common data pool. The 25 ns access time means the SRAM can complete a read or write cycle in 25 ns, which keeps up with many mid-range processors without inserting wait states — important for timing-closure in a 40 MHz or slower bus. For a system running a 40 MHz bus clock (25 ns period), this SRAM can deliver data within one clock cycle, assuming the address is stable at the clock edge. At higher clock speeds, the designer needs to account for the access time plus propagation delays through buffers and traces — the 25 ns spec leaves a tight margin above 40 MHz. This matters for high-throughput data logging or frame-buffer applications where every nanosecond counts. The 100-LQFP package has a 14x14 mm body.","metaTitle":"Infineon CY7C025E-25AXI 128Kbit Dual-Port SRAM, 25 ns","metaDescription":"Infineon CY7C025E-25AXI dual-port asynchronous SRAM, 128Kbit (8K x 16), 25 ns access time, -40°C to 85°C, 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":"Tray","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"25 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":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"25ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C025E-25AXI?","answer":"The base product number CY7C025 covers multiple speed and temperature variants.
