nonvolatile, read/write storage solution for a wide
range of applications. The LH28F800BG-L can
operate at V
CC
= 2.7 V and V
PP
= 2.7 V. Its low
voltage operation capability realizes longer battery
life and suits for cellular phone application. Its boot,
parameter and main-blocked architecture, flexible
voltage and enhanced cycling capability provide for
highly flexible component suitable for portable
terminals and personal computers. 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 LH28F800BG-L offers
two levels of protection : absolute protection with
V
PP
at GND, selective hardware boot block locking.
These alternatives give designers ultimate control of
their code security needs.
