The W28F321, a 4-Plane Page Mode Dual Work (Simultaneous Read while Erase/Program) Flash memory, is a low power, high density, cost efficiency, 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 W28F321 provides high performance asynchronous page mode. It allows code execution directly from Flash, thus eliminating time-consuming wait states. Furthermore, its configurative partitioning architecture allows flexible dual work operation.
The memory array block architecture utilizes Enhanced Data Protection features, and provides separate Parameter and Main Blocks that provide maximum flexibility for safe nonvolatile code and data storage.
Fast program capability is provided through the use of high speed Page Buffer Program. Special OTP (One Time Program) block provides an area to store permanent code such as a unique number.
