The CY7C028AV-25AXCT is a 1Mbit dual-port asynchronous SRAM organized as 64K x 16 bits, with a 25 ns access time and a parallel interface. It allows two independent bus masters to read and write the same memory array without external arbitration logic.
In a dual-port system, both ports can initiate a cycle simultaneously; the internal arbitration logic resolves collisions with a fixed priority scheme.
Cypress offers the CY7C028V-25AXCT (if still active) as a pin-compatible drop-in in the same 100-TQFP package. For a broader search, look at IDT (Renesas) 1Mbit dual-port asynchronous SRAMs in 100-TQFP, such as the 70V28 series, but verify pinout and timing compatibility against your design.
The package is 100-LQFP, also specified as 100-TQFP (14x14 mm body, 0.5 mm pitch). The part is supplied in Tape & Reel.
The technology is SRAM - Dual Port, Asynchronous. It is a volatile memory with a parallel interface.
