DESCRIPTION
– Commerical 0°C – +70°C
SHARP’s LH28F400BG Flash memory with SmartVoltage tech-
nology is a high-density, low-cost, nonvolatile, read/write storage
solution for a wide range of applications. LH28F400BG can operate
at V = 2.7 V and V = 2.7 V. Its low voltage operation capability
– Industrial -40°C – +85°C
• Enhanced data protection features
– Absolute protection with V = GND
PP
– Block erase/word write lockout during power transitions

realize battery life and suits for cellular phone application.
Its boot, parameter and main-blocked architecture, flexible voltage
and extended cycling provide for highly flexible component suit-
able for portable terminals and personal computers. Its enhanced
suspend capabilities provide for an ideal solution for code and data
storage applications. For secure code storage appli-cations, such
as networking, where code is either directly executed out of flash
or downloaded to DRAM, the LH28F400BG offers two levels of
– Boot blocks protection with WP = V
IL
• Optimized array blocking architecture
– Two 4K-word boot blocks
– Six 4K-word parameter blocks
– Seven 32K-word main blocks
– Top or bottom boot locations
• Automated word write and block erase
– Command user interface
protection: absolute protection with V at GND, selective hardware
– Status register

boot block locking. These alternatives give designers ultimate
control of their code security needs.
• Extended cycling capability
– 100,000 block erase cycles
