The CY7C144AV-25AXCT is a 64Kbit (8K x 8) dual-port asynchronous SRAM from Infineon, organized as 8K words of 8 bits each. The dual-port architecture gives two independent processors or controllers simultaneous read/write access to the same memory array, which is the standard approach for shared-message buffers in telecom line cards, industrial controllers, and multiprocessor systems. The 25 ns access time sets the timing floor for both ports, with a symmetric write cycle time of 25 ns.
Infineon lists the CY7C144AV-25AXCT as Obsolete. For an active BOM line, this part must be sourced through independent distribution or the spot market, where availability and pricing are confirmed per RFQ.
The part operates from 3V to 3.6V, a narrow 3.3V nominal rail typical of late-90s/early-2000s SRAM designs.
