AT45DB642

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.
