The Infineon CY7C024-25AXCT is a 64Kbit dual-port asynchronous SRAM organized as 4K x 16 bits. It provides two independent ports with separate address, data, and control lines, allowing simultaneous read/write access from two bus masters — a common architecture for shared memory, mailbox communication, or data buffering in multiprocessor systems.
For a processor running at 40 MHz (25 ns cycle), this part can deliver data in one clock if the address setup and hold margins are tight; at 50 MHz (20 ns cycle) you'll need one wait state. This is a mid-speed dual-port — faster than the 35 ns and 45 ns siblings in the CY7C024 family, but not the 15 ns or 12 ns high-speed variants. If your bus runs above 50 MHz, look for a faster grade.
The 100-TQFP footprint is shared with other Cypress/Infineon dual-port SRAMs in the CY7C024 and CY7C025 families, so a board designed for this part can often accept a different density or speed grade without a layout change — useful if you need to substitute a faster or larger variant during the last-time-buy window.
