DESCRIPTION
SHARP’s LH28F800SGHB is a 8M flash memory with
SmartVoltage technology and features a high-density, low-cost,
nonvolatile, read/write storage solution for a wide range of
applications. It is organized as 512K-word of 16-bits. The
LH28F800SGHB can operate at VCC = 2.7 V and VPP = 2.7 V. Its
low voltage operation capability realizes longer battery life which
makes it suitable for cellular phone applications. Its symmetri-
cally-blocked architecture, flexible voltage and extended cycling
make it a highly flexible component suitable for resident flash
arrays, SIMMs and memory cards. Its enhanced suspend
capabilities make it an ideal solution for code and 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 LH28F800SGHB offers three levels of
protection; absolute protection with VPP at GND, selective hard-
ware block locking, or flexible software block locking. These alter-
natives give designers ultimate control of their code security needs.
The LH28F800SGHB is manufactured on SHARP’s 0.4 µm
ETOX™ V process technology. It comes in an industry-standard
package; the 48-ball CSP ideal for board constrained applications.
