SUMMARY DESCRIPTION
The M50FW080 is an 8 Mbit (1Mbit x8) non-vola-
tile memory that can be read, erased and repro-
grammed. These operations can be performed
using a single low voltage (3.0 to 3.6V) supply. For
fast programming and fast erasing in production
lines an optional 12V power supply can be used to
reduce the programming and the erasing times.
The memory is divided into blocks that 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 Pro-
gram or Erase commands from modifying the
memory. Program and Erase commands are writ-
ten 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 required to control the memory is consistent
with JEDEC standards.
Two different bus interfaces are supported by the
memory. The primary interface, the Firmware Hub
(or FWH) Interface, uses Intel’s proprietary FWH
protocol. This has been designed to remove the
need for the ISA bus in current PC Chipsets; the
M50FW080 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 to a PC
Motherboard.
