The CY7C025E-55AXC is a 128Kbit dual-port asynchronous SRAM organized as 8K x 16, with a 55 ns access time and a 4.5–5.5 V supply range. It provides two independent ports with separate address, data, and control lines, allowing two bus masters to read/write the same memory array without external arbitration logic.
55 ns access and 5 V supply — timing and rail constraints
The supply range is 4.5–5.5 V, so a 5 V rail is required — this part does not operate at 3.3 V. The 100-LQFP package with 0.5 mm pitch needs a controlled impedance layout for the parallel bus.
Obsolete — sourcing for legacy BOM lines
Infineon lists the CY7C025E-55AXC as Obsolete. The 100-TQFP (14x14) footprint is shared with other dual-port SRAMs in the CY7C025 family, easing cross-reference evaluation.
