The Cypress CY7C141-25JXCT is an 8Kbit dual-port asynchronous SRAM organized as 1K x 8, with a 25 ns access time that matches the bus timing of many legacy 5 V DSPs and ASICs without inserting wait states.
The CY7C141-25JXCT is listed as obsolete. Any new design should migrate to a current-generation dual-port SRAM or a shared-memory scheme using a modern asynchronous SRAM with an external arbitration controller — the 25 ns access-time class is still served by active parts from vendors like Renesas (IDT) and GSI Technology, though package and supply voltage may differ.
52-PLCC footprint — rework and socket considerations
The 52-PLCC (J-lead) package measures 19.13 x 19.13 mm per the supplier device package spec. Unlike QFP or BGA, the J-lead form factor is socket-friendly — many production and test sockets exist for PLCC, which aids prototyping and field replacement. For rework, the J-lead sits flush against the PCB pad; a hot-air station with a PLCC nozzle works, but the lead pitch is wide enough that a standard soldering iron with a fine tip can hand-solder individual leads if the board has accessible vias.
Commercial temperature grade — deployment boundary
If the board sees condensation or thermal cycling beyond 70°C, the part is out of spec — plan for active cooling or a higher-temperature-grade dual-port SRAM alternative.
