EEPROM
The
SMARC
‐
iMX8MM
module
includes
an
I2C
serial
EEPROM
available
on
the
I2C_GP
bus.
An
On
Semiconductor
24C32
or
equivalent
EEPROM
is
used
in
the
module.
The
device
operates
at
1.8V.
The
Module
serial
EEPROM
is
placed
at
I2C
slave
addresses
A2
A1
A0
set
to
0
(I2C
slave
address
50
hex,
7
bit
address
format
or
A0
/
A1
hex,
8
bit
format)
(for
I2C
EEPROMs,
address
bits
A6
A5
A4
A3
are
set
to
binary
0101
convention).
The
module
serial
EEPROM
is
intended
to
retain
module
parameter
information,
including
serial
number.
The
module
serial
EEPROM
data
structure
conforms
to
the
PICMG®
EEEP
Embedded
EEPROM
Specification.
Note:
The

ID
memory
layout
is
now
follow
the
mainline
and
as
follows.
