(FOR TSOP, CSP)

8 M-bit (512 kB x 16) SmartVoltage

Flash Memories

LH28F800BG-L/BGH-L (FOR TSOP, CSP)

DESCRIPTION

The LH28F800BG-L/BGH-L flash memories with

SmartVoltage technology are high-density, low-cost,

nonvolatile, read/write storage solution for a wide

range of applications. The LH28F800BG-L/BGH-L

low voltage operation capability realizes longer

battery life and suits for cellular phone application.

Their

boot,

parameter

and

main-blocked

architecture, flexible voltage and enhanced cycling

capability provide for highly flexible component

suitable for portable terminals and personal

computers. 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

LH28F800BG-L/BGH-L offer two levels of protection

hardware boot block locking. These alternatives

give designers ultimate control of their code security

needs.
