Microsemi Corporation's WE128K32-250G2UM is a 128K x 32 bit parallel CMOS EEPROM module featuring a 250ns maximum access time. This device offers a memory density of 4Mbit and supports an asynchronous operating mode. The WE128K32 series component can be user-configured as a 512K x 8 configuration, providing flexibility in memory mapping. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement, and requires a programming voltage of 5V. The operating temperature spans from -55°C to +125°C. Encased in a 68-lead CQFP package with gull-wing terminals on a 1.27mm pitch, this surface-mount component is constructed from ceramic and metal-sealed cofired materials. The write cycle time is a maximum of 10ms. Applications for this robust component include aerospace, defense, and industrial systems requiring high-reliability non-volatile memory.
