current PC Chipsets; the M50LPW040 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)
and PLCC32 packages and it is supplied with all
the bits erased (set to ’1’).
SIGNAL DESCRIPTIONS
There are two different bus interfaces available on
this part. The active interface is selected before
power-up or during Reset using the Interface Con-
figuration Pin, IC.
The signals for each interface are discussed in the
Low Pin Count (LPC) Signal Descriptions section
and the Address/Address Multiplexed (A/A Mux)
Signal Descriptions section below. The supply sig-
nals are discussed in the Supply Signal Descrip-
tions section below.
