The Cypress CY7C025-15AXI is a 128Kbit dual-port asynchronous SRAM organized as 8K x 16 bits. It gives two independent bus masters simultaneous read/write access to the same memory.
In a shared-memory design, that number eats directly into the setup-and-hold budget of the receiving controller.
No last-time-buy window remains open from the manufacturer. The only channel for this part is the independent surplus and broker market.
There is no single official replacement part number from Cypress, but faster speed grades in the same CY7C025 family (such as the -12 or -10 ns variants) are pin-compatible drop-in replacements in the same 100-TQFP package. They recover bus margin without a board layout change.
It is a 128Kbit dual-port asynchronous SRAM organized as 8K x 16 bits, with a 15 ns access time, 4.5V to 5.5V supply, and an industrial temperature range of -40°C to 85°C. It comes in a 100-TQFP (14x14 mm) package.
Yes, a faster speed grade in the same CY7C025 family (e.g., 12 ns or 10 ns) is a pin-compatible drop-in. The 100-TQFP footprint is identical, so no board layout change is needed. The faster part recovers bus timing margin for higher-clock-rate systems.
