Microsemi Corporation WE256K32-250G2TIE is a 256K x 32 bit CMOS EEPROM module with a 250ns asynchronous parallel interface. This component offers a memory density of 8Mb, organized as 262,144 words of 32 bits each. It features a minimum data retention of 10 years and a write endurance of 10,000 cycles. The module operates from a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement, and is suitable for operation within an industrial temperature range of -40°C to +85°C. Packaged in a 68-lead CQFP (Ceramic Quad Flat Pack) with gull-wing terminals on a 1.27mm pitch, it is designed for surface mounting. Applications span aerospace, defense, and industrial control systems requiring reliable non-volatile data storage.
