The product, which is Page Mode Flash memory, is a high density, low cost, nonvolatile read/write storage solution for a
wide range of applications. The product can operate at V
The product supports high performance page mode. It allows code execution directly from Flash, thus eliminating time
consuming wait states.
Fast program capability is provided through the use of high speed Page Buffer Program.
The block locking scheme is available for memory array and this scheme provides maximum flexibility for safe nonvolatile
code and data storage.
OTP (One Time Program) block provides an area to store security code and to protect its code.
