SUMMARY DESCRIPTION
The M50FW016 is a 16 Mbit (2Mb 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, 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
Program or Erase commands from modifying the
memory. 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 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
M50FW016 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.
The memory is offered in TSOP40 (10 x 20mm)
package and it is supplied with all the bits erased
(set to ’1’).
