SHARP’s LH28F008SAN-85 8M-bit Flash Memory is the highest density nonvolatile read/write solution for solid state
storage. The LH28F008SA’s extended cycling, symmetrically blocked architecture, fast access time, write automation and
low power consumption provide a more reliable, lower power, lighter weight and higher performance alternative to tradi-
tional rotating disk technology. The LH28F008SAN-85 brings new capabilities to portable computing. Application and
operating system software stored in resident flash memory arrays provide instant-on rapid execute-in-place and protection
from obsolescence through in-system software updates. Resident software also extends system battery life and increases
reliability by reducing disk drive accesses.
For high density data acquisition applications, the LH28F008SAN-85 offers a more cost-effective and reliable alternative to
SRAM and battery. Traditional high density embedded applications, such as telecommunications, can take advantage of
the LH28F008SA’s nonvolatility, blocking and minimal system code requirements for flexible firmware and modular soft-
ware designs.
The LH28F008SAN-85 is offered in 44-lead PSOP package. Pin assignments simplify board layout when integrating
multiple devices in a flash memory array or subsystem. This device uses an integrated Command User Interface and state
machine for simplified block erasure and byte write. The LH28F008SAN-85 memory map consists of 16 separately
erasable 64K-byte blocks.
SHARP’s LH28F008SAN-85 employs advanced CMOS circuitry for systems requiring low power consumption and noise
immunity. Its 85ns access time provides superior performance when compared with magnetic storage media. A deep
powerdown mode lowers power consumption to 50µW maximum thru V
mentation and other low-power applications. The RP# power control input also provides absolute data protection during
system powerup/down.
