Serial Identification (EEPROM)

The HFCT-5760NL/NP is

compliant with the SFP MSA,

which defines the serial

identification protocol. This

protocol uses the 2-wire serial

CMOS E2PROM protocol of the

ATMEL AT24C01A or similar.

MSA compliant, example

contents of the HFCT-5760NL/

NP serial ID memory are defined

in Table 3.

Table 3. EEPROM Serial ID Memory Contents

Notes:

1. Address 68-83 specify a unique identifier.

2. Address 84-91 specify the date code.

3. Addresses 63 and 95 are check sums. Address 63 is the check sum for bytes 0-62 and address 95 is the check sum for bytes 64-94.

4. Address 96-127 is vendor specific data.
