Additional Details

The IDT7028L20PFI operates from a single 5V power supply and provides separate data input and output pins for each port, supporting true dual-port operation. The integrated arbitration logic effectively manages simultaneous access requests, preventing data collisions and ensuring data integrity. The interrupt flag signal simplifies memory management by indicating when memory is available for reading or writing. The 20ns access time enables rapid data retrieval, minimizing latency in the system. The CMOS technology contributes to low power dissipation, enhancing the overall energy efficiency of the system. The device is available in a Plastic Quad Flat Pack (PQFP) package.
