2 / 11 page  6.42 IDT7054S/L High-Speed 4K x 8 FourPort™ Static RAM Military, Industrial and Commercial Temperature Ranges 2 Fabricated using IDT’s CMOS high-performance technology, this FourPort SRAM typically operates on only 750mW of power. Low-power (L) versions offer battery backup data retention capability, with each port typically consuming 50µW from a 2V battery. The IDT7054 is packaged in a ceramic 108-pin Pin Grid Array (PGA) and a 128-pin Thin Quad Flatpack (TQFP). The military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML,makingitideallysuitedtomilitarytemperatureapplicationsdemand- ing the highest level of performance and reliability. externallyarbitratedorwithstandcontentionwhenallportssimultaneously access the same FourPort RAM location. The IDT7054 provides four independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. It is the user’s responsibility to ensure data integrity when simultaneously accessing the same memory locationfromallports.Anautomaticpowerdownfeature,controlledby CE, permitstheon-chipcircuitryofeachporttoenteraverylowpowerstandby power mode. NOTES: 1. All VCC pins must be connected to the power supply. 2. All GND pins must be connected to the ground supply. 3. Package body is approximately 1.21 in x 1.21 in x .16 in. 4. This package code is used to reference the package diagram. 5. This text does not indicate orientation of the actual part-marking.
