Technical Specifications

The IDT7007S25PF operates on a single 5V power supply. It comes in a Plastic Flat Pack package. The device incorporates independent address, data, and control signals for each port, enabling asynchronous read and write operations. The on-chip arbitration logic efficiently manages conflicts arising from simultaneous access attempts to the same memory location.
