Summary description
The M50FLW080 is a 8 Mbit (1M x8) non-volatile memory that can be read, erased and
reprogrammed. These operations can be performed using a single low voltage (3.0 to 3.6V)
supply. For fast programming and fast erasing on production lines, an optional 12V power
supply can be used to reduce the erasing and programming time.
The memory is divided into 16 Uniform Blocks of 64 KBytes each, three of which are divided
into 16 uniform sectors of 4 KBytes each (see
Appendix A
for details). All blocks and sectors
can be erased independently. So, it is possible to preserve valid data while old data is
erased. Blocks can be protected individually to prevent accidental program or erase
commands from modifying their contents.
Program and erase commands are written to the Command Interface of the memory. An on-
chip Program/Erase Controller simplifies the process of programming or erasing the
memory by taking care of all of the special operations that are required to update the
memory contents. The end of a program or erase operation can be detected and any error
conditions identified. The command set to control the memory is consistent with the JEDEC
standards.
Two different bus interfaces are supported by the memory:
The primary interface, the FWH/LPC Interface, uses Intel’s proprietary Firmware Hub
(FWH) and Low Pin Count (LPC) protocol. This has been designed to remove the need
for the ISA bus in current PC Chipsets. The M50FLW080 acts as the PC BIOS on the
Low Pin Count bus for these PC Chipsets.
The secondary interface, the Address/Address Multiplexed (or A/A Mux) Interface, is
designed to be compatible with current Flash Programmers, for production line
programming prior to fitting the device in a PC Motherboard.

In order to meet environmental requirements, ST offers the M50FLW080A and
M50FLW080B in ECOPACK packages. ECOPACK packages are Lead-free and RoHS
compliant. ECOPACK is an ST trademark. ECOPACK specifications are available at:

The memory is supplied with all the bits erased (set to ’1’).
