M28F008
The M28F008 8-Mbit FlashFile Memory is the highest density nonvolatile read/write solution for solid state
storage. The M28F008’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 traditional rotating disk technology. The M28F008 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 M28F008 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 M28F008’s nonvolatility, blocking and minimal system code requirements for flexible firmware
and modular software designs.
The M28F008 is offered in 40-lead sidebrazed DIP and 42-lead Flatpack packages. This device uses an
integrated Command User Interface and state machine for simplified block erasure and byte write. The
M28F008 memory map consists of 16 separately erasable 64 Kbyte blocks.
The M28F008 employs advanced CMOS circuitry for systems requiring low power consumption and noise
immunity. Its 100 ns access time provides superior performance when compared with magnetic storage media.
A deep powerdown mode lowers power consumption to 500
♣µW
maximum thru V
CC
. The RP power control
input also provides absolute data protection during system powerup/down.
