The Microsemi Corporation WMS256K16-25FLMA is a high-speed, asynchronous CMOS SRAM with a memory organization of 256K words by 16 bits, providing a total density of 4 Megabits. Featuring an access time of 25 nanoseconds, this component is designed for demanding applications. It operates across a wide temperature range of -55°C to +125°C and supports a supply voltage from 4.5V to 5.5V, with a nominal 5V operation. A key feature is its 2V minimum data retention capability, crucial for battery-backed systems. The WMS256K16-25FLMA is housed in a 44-lead ceramic, metal-sealed cofired flatpack (DFP) package, suitable for surface mounting. This memory device is compliant with MIL-STD-883 screening standards and finds utility in aerospace, defense, and industrial control systems requiring robust and reliable memory solutions.
