DESCRIPTION
The LH28F800SG-L flash memory with Smart
Voltage technology is a high-density, low-
cost, nonvolatile, read/write storage solution for a
wide range of applications. The LH28F800SG-L
can operate at VCC = 2.7 V and VPP = 2.7 V. Its
low voltage operation capability realizes longer
battery life and suits for cellular phone application.
Its symmetrically-blocked architecture, flexible
voltage and enhanced cycling capability provide for
highly flexible component suitable for resident flash
arrays, SIMMs and memory cards. Its enhanced
suspend capabilities provide for an ideal solution for
code + data storage applications. For secure code
storage applications, such as networking, where
code is either directly executed out of flash or
downloaded to DRAM, the LH28F800SG-L offers
three levels of protection : absolute protection with
VPP at GND, selective hardware block locking, or
flexible software block locking.These alternatives
give designers ultimate control of their code security
needs.
