It provides two independent ports with separate address, data, and control lines, allowing two processors or controllers to read and write the same memory array without bus contention. The 7.5 ns access time and 83 MHz clock frequency support back-to-back read/write cycles on both ports, making it suited for shared-buffer applications in networking, telecom, and video processing where low-latency data exchange is required. The 7.5 ns access time is the delay from address assertion to valid data on the outputs. In a shared-memory system clocked at 83 MHz (12 ns period), the access time leaves roughly 4.5 ns of setup margin before the next clock edge — enough for most 3.3 V logic families, but tight if the board has long trace runs or multiple loads. The synchronous interface eliminates the dead cycles of asynchronous dual-port parts; both ports can perform a read or write every clock cycle, doubling throughput compared to a single-port SRAM with an arbiter. ## Obsolete — sourcing reality and what to expect Infineon lists the CY7C09289V-7AXCT as Obsolete. No official successor part number has been published for this specific speed and package variant. Production has ended; the only available units are from surplus or broker inventory. ## Package and footprint — 100-TQFP The footprint matches the standard 100-TQFP land pattern; no exposed pad or thermal slug to route.","metaTitle":"Infineon CY7C09289V-7AXCT 1Mbit Dual-Port SRAM, 7.5 ns","metaDescription":"CY7C09289V-7AXCT by Infineon: 1Mbit synchronous dual-port SRAM, 64Kx16, 7.5 ns access, 83 MHz clock, 3V-3.6V, 100-TQFP.
