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.","metaTitle":"CY7C025E-55AXC 128Kbit Dual-Port SRAM 55ns 100-LQFP Obsolete","metaDescription":"Infineon CY7C025E-55AXC dual-port asynchronous SRAM, 128Kbit (8K x 16), 55 ns access, 4.5–5.5 V, 100-LQFP.
