GENERAL DESCRIPTION
The W28F641, a 4-Plane Page Mode Dual Work (Simultaneous Read while Erase/Program) Flash memory, is a low power, high density, low cost, nonvolatile read/write storage solution for a wide range of applications. The product can be operated at VDD = 2.7V to 3.6V and VPP = 1.65V to 3.6V or 11.7V to 12.3V. Its low voltage operation capability greatly extends battery life for portable applications.

The W28F641 provides high performance asynchronous page mode. It allows code execution directly from Flash, thus eliminating time-consuming wait states. Furthermore, the configurative partitioning architecture allows flexible dual work operation.
