Description
The AT45DB642 is a 2.7-volt only, dual-interface Flash memory ideally suited for a
wide variety of digital voice-, image-, program code- and data-storage applications. The
dual-interface of the AT45DB642 allows a dedicated serial interface to be connected to a
DSP and a dedicated parallel interface to be connected to a microcontroller or vice versa.
