The Cypress CY7C056V-15AXC is a 576Kbit dual-port asynchronous SRAM organized as 16K x 36 bits. Its 15 ns access time allows two independent processors or controllers to read and write the same memory array with minimal wait-state insertion on a shared bus — the dual-port architecture eliminates the arbitration logic a single-port RAM would need for a mailbox or FIFO buffer between two clock domains.
Yes, the CY7C056V-15AXC is obsolete. Cypress has marked it end-of-life with no direct replacement announced. Any remaining units are sourced through surplus and independent distribution channels.
The CY7C056V-15AXC is a 576Kbit dual-port asynchronous SRAM organized 16K x 36 bits with a 15 ns access time. It operates on a 3.0 V to 3.6 V supply, uses a parallel interface, and is housed in a 144-TQFP (20x20 mm) surface-mount package rated for 0°C to 70°C.
