1. Description
The Atmel AT24MAC402 and AT24MAC602 provides 2048 bits of Serial Electrically-Erasable Programmable
Read-Only Memory (EEPROM) organized as 256 words of eight bits each and is accessed via an
I2C-compatible (2-wire) serial interface. In addition, AT24MAC402/602 incorporates an easy and inexpensive
method to obtain a globally unique MAC or EUI address (EUI-48 or EUI-64). AT24MAC402 is an EUI-48
compatible device that contains a 48-bit EUI address, and AT24MAC602 is an EUI-64 compatible device that
contains a 64-bit EUI address.
The EUI-48 and EUI-64 addresses can be assigned as the actual physical address of a system hardware device
or node or it can be assigned to a software instance. These addresses are factory programmed by Atmel and
permanently write protected in an extended memory block located outside of the standard 2-Kbit bit memory
array.
In addition, the AT24MAC402/602 provides the value added feature of a factory-programmed, guaranteed
unique 128-bit serial number located in the extended memory block (same area as the EUI address values).
The serial number is Atmel factory-programmed and permanently write protected. This 128-bit serial number is
compatible with all AT24CS, AT93CS, and AT25S family serial numbers, therefore, providing guaranteed
unique serial numbers for any application that is also using Atmel Serial EEPROMs.
The first-half of the AT24MAC402/602 incorporates a permanent and a reversible software write protection
feature while a hardware write protect feature for the entire array is available via an external pin. The permanent
software write protection is enabled by sending a special command to the device. This protection cannot be
reversed once executed. However, the reversible software write protection can be reversed by sending and
executing a special command. The hardware write protection is controlled by the WP pin state and can be used
to protect the entire array regardless of whether or not the software write protection has been enabled. The
software and hardware write protection features allow the user the flexibility to protect no portion of the memory,
the first-half of the memory, or the entire memory array depending on the specific needs of the application.
The device is optimized for use in many industrial and commercial applications where low-power and
low-voltage operations are essential. The AT24MAC402/602 is available in space saving 8-lead JEDEC SOIC,
8-lead TSSOP, 8-pad UDFN, and 5-lead SOT23 packages. Both devices operate across a wide supply voltage
range from 1.7V to 5.5V VCC.
