ETOX
TM*
Flash Technology
Not designed or rated as radiation hardened
The product, which is 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
operate at V
CC
=2.7V-3.6V and V
PP
=1.65V-3.6V or 11.7V-12.3V. Its low voltage operation capability greatly extends
battery life for portable applications.
The product provides high performance asynchronous page mode. It allows code execution directly from Flash, thus
eliminating time consuming wait states. Furthermore, its newly 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.
