IDT7027S/L
High-Speed 32K x 16 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Description
circuitry of each port to enter a very low standby power mode.
FabricatedusingIDT’sCMOShigh-performancetechnology,these
devices typically operate on only 750mW of power. The IDT7027 is
packagedina100-pinThinQuadFlatpack(TQFP)anda108-pinceramic
Pin Grid Array (PGA).
Military grade product is manufactured in compliance with the
latest revision of MIL-PRF-38535 QML, making it ideally suited to
military temperature applications demanding the highest level of
performanceandreliability.
The IDT7027 is a high-speed 32K x 16 Dual-Port Static RAM,
designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a
