That makes it the natural fit for shared-memory designs where two processors, a processor and an FPGA, or a processor and a DMA engine need a common scratchpad without bus-turnaround dead cycles. The 64-TQFP package (14x14mm body) is a standard fine-pitch QFP. The 55 ns access time and 55 ns write cycle time support back-to-back reads or writes at that rate. The CY7C144-55AXC is marked obsolete by Cypress (now Infineon). That means no further factory orders, no last-time-buy window still open. If you have this on a BOM for a production board that is still being built, you are on the surplus and broker channel now. ## Sourcing the CY7C144-55AXC today We source it through our independent supply network — verified stock from surplus inventories, overstock from EMS partners, and qualified broker lots. Every unit we quote is inspected and tested to the original Cypress datasheet parameters before it ships. Submit an RFQ with your quantity and target date, and we will pull the inventory and quote firm.","metaTitle":"CY7C144-55AXC Cypress 64Kbit Dual-Port SRAM, 55 ns, 64-TQFP","metaDescription":"Cypress CY7C144-55AXC 64Kbit (8K x 8) asynchronous dual-port SRAM. 55 ns access time, 4.5V-5.5V supply, 0°C-70°C.
