The AT45DB041E-SHN-T DataFlash from Dialog Semiconductor is a NOR flash 4M memory, featuring a fast access rate of up to 85Mhz and operating voltage from 1.65V to 3.6V. It is designed for data storage, mass data storage, and as a buffer between a processor and external memory. It has a 4Mbit memory capacity with the ability to address four distinct pages. It can store word sizes up to 512 bytes. It features a hardware write protect feature that locks the entire memory array or a portion of the memory array during write operations and provides full end-user control. It also has a hardware Data/Address Bus assertion control feature that eliminates the need for special software overhead when accessing pages. Additionally, the AT45DB041E-SHN-T has robust and reliable electromechanical data retention characteristics and data retention periods of more than 100 years.
