Features:  
Description:  
• Pre-programmed Globally Unique, 48-bit Node  
Address  
The Microchip Technology Inc. 25AA02E48 is a 2 Kbit  
Serial Electrically Erasable Programmable Read-Only  
Memory (EEPROM). The memory is accessed via a  
simple Serial Peripheral Interface (SPI) compatible  
serial bus. The bus signals required are a clock input  
(SCK) plus separate data in (SI) and data out (SO)  
lines. Access to the device is controlled through a Chip  
Select (CS) input.  
• Compatible with EUI-48™ and EUI-64™  
• 10 MHz max. Clock Frequency  
• Low-Power CMOS Technology:  
- Max. Write Current: 5 mA at 5.5V  
- Read Current: 5 mA at 5.5V, 10 MHz  
- Standby Current: 1 μA at 2.5V  
• 256 x 8-bit Organization  
Communication to the device can be paused via the  
hold pin (HOLD). While the device is paused, transi-  
tions on its inputs will be ignored, with the exception of  
Chip Select, allowing the host to service higher priority  
interrupts.  
• Write Page mode (up to 16 bytes)  
• Sequential Read  
• Self-Timed Erase and Write Cycles (5 ms max.)  
• Block Write Protection:  
The 25AA02E48 is available in the standard 8-lead  
SOIC and 6-lead SOT-23 packages.  
- Protect none, 1/4, 1/2 or all of array  
• Built-in Write Protection:  
Package Types (not to scale)  
- Power-on/off data protection circuitry
