LH28F800SG-L/SGH-L (FOR TSOP, CSP)
LH28F800SG-L/SGH-L
(FOR TSOP, CSP)
DESCRIPTION
The LH28F800SG-L/SGH-L flash memories with
SmartVoltage technology are high-density, low-cost,
nonvolatile, read/write storage solution for a wide
range of applications. The LH28F800SG-L/SGH-L
can operate at V
CC
= 2.7 V and V
PP
= 2.7 V. Their
low voltage operation capability realizes longer
battery life and suits for cellular phone application.
Their symmetrically-blocked architecture, flexible
voltage and enhanced cycling capability provide for
highly flexible component suitable for resident flash
arrays, SIMMs and memory cards. Their 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/SGH-L
offer three levels of protection : absolute protection
with V
PP
at GND, selective hardware block locking,
or flexible software block locking.These alternatives
give designers ultimate control of their code security
needs.
