Reading the data
The information is accessed through the SCL and SDA connector pins of the mod-
ule. The SFF-8431 Revision 3.2 specification contains all the timing and address-
ing information required for accessing the data in the EEPROM.
The device address used to read the Serial ID data is 1010000X(A0h), and the ad-
dress to read the diagnostic data is 1010001X(A2h). Any other device addresses
will be ignored.
MOD_ABS, pin 6 on the transceiver, is connected to Logic 0 (Ground) on the
transceiver.
SCL, pin 5 on the transceiver, is connected to the SCL pin of the EEPROM.
SDA, pin 4 on the transceiver, is connected to the SDA pin of the EEPROM.
The EEPROM Write Protect pin is internally tied to ground with no external ac-
cess, allowing write access to the customer-writable field (bytes 128 – 247 of ad-
dress 1010001X). Note: address bytes 0 – 127 are not write protected and may
cause diagnostic malfunctions if written over.
Decoding the data
The information stored in the EEPROM, including the organization and the digi-
tal diagnostic information, is defined in the Small Form Factor Committee docu-
ment SFF-8472 Revision 10.3, dated December 1, 2007.
