It operates from a 4.5 V to 5.5 V supply and is rated over the -40°C to 85°C industrial temperature range, making it suitable for factory-floor PLCs, outdoor base stations, or embedded systems that need fast, volatile scratchpad memory without refresh overhead. The 15 ns access time and 15 ns write cycle time are specified in the datasheet. This part is marked obsolete by the manufacturer. For BOM lines that require the CY7C185-15VI, supply runs through independent distribution and surplus channels. If you are qualifying a new design, consider a pin-compatible 64Kbit asynchronous SRAM in a 28-SOJ footprint from the same family — but no direct drop-in replacement is documented here. Housed in a 28-SOJ (0.300\" body width, 7.62 mm) surface-mount package. The SOJ footprint is common for SRAM modules of this era; verify the land pattern against your PCB layout before ordering.
