Description:

The P25T22L/12L is a serial interface Flash memory device designed for use in a wide variety of high-volume 

consumer based applications in which program code is shadowed from Flash memory into embedded or 

external RAM for execution. The flexible erase architecture of the device, with its page erase granularity it is 

ideal for data storage as well, eliminating the need for additional data storage devices.

The erase block sizes of the device have been optimized to meet the needs of today's code and data storage 

applications. By optimizing the size of the erase blocks, the memory space can be used much more efficiently. 

Because certain code modules and data storage segments must reside by themselves in their own erase 

regions, the wasted and unused memory space that occurs with large sectored and large block erase Flash 

memory devices can be greatly reduced. This increased memory space efficiency allows additional code 

routines and data storage segments to be added while still maintaining the same overall device density. 

Specifically designed for use in many different systems, the device supports read, program, and erase 

operations with a wide supply voltage range of 1.65V to 2.0V. No separate voltage is required for programming 

and erasing.
