Two independent ports allow simultaneous read or write from two bus masters. ## 55 ns access time — timing margin for the bus 55 ns access time and 55 ns write cycle time (word/page). Symmetrical read/write window simplifies timing closure in asynchronous designs. ## Obsolete — last-time-buy reality No official successor order code is published for this exact dual-port density and speed grade. The part is no longer manufactured and is not available through the factory channel. For a BOM line that requires this exact order code — for a legacy board repair, a machine-tool controller, or a telecom line card that cannot be redesigned — the only sourcing path is the independent surplus and broker market. No production-status claim is made beyond the Obsolete designation. ## Commercial temperature grade — indoor use only Not suitable for outdoor or unheated deployment without active thermal management.","metaTitle":"Cypress CY7C136-55JXCT 16Kbit Dual-Port SRAM, 55 ns, Obsolete","metaDescription":"Cypress CY7C136-55JXCT 16Kbit dual-port asynchronous SRAM, 55 ns access time, 4.5-5.5V, 52-PLCC.
