That margin shrinks if the bus is shared or has additional buffers. ## Commercial temperature grade — what it limits It is not suited for outdoor base stations, engine bays, or unheated enclosures where the ambient can dip below freezing or exceed 70°C. Infineon lists the CY7C199CN-15ZXC as obsolete. Buyers should expect to qualify date codes and inspect for counterfeit risk, as is standard for obsolete components sourced outside the factory channel.","metaTitle":"Infineon CY7C199CN-15ZXC SRAM, 256Kbit, 15 ns, 28-TSOP I","metaDescription":"Infineon CY7C199CN-15ZXC 256Kbit (32K x 8) asynchronous SRAM with 15 ns access time. 4.5V-5.5V supply, commercial temp range.
