Technical Specifications

The IDT70V261S25PF operates from a single 3.3V power supply. It is available in a Plastic Flat Pack package. The device features independent address, data, and control signals for each port, facilitating asynchronous read and write operations. The integrated arbitration logic resolves conflicts when both ports attempt to access the same memory location concurrently. Detailed specifications, including electrical characteristics and package information, can be found in the official IDT datasheet.
