• Pre-programmed Globally Unique, 48-bit Node
Address
The Microchip Technology Inc. 24AA02E48/
24AA025E48 (24AAXXXE48*) is a 2 Kbit Electrically
Erasable PROM. The device is organized as two
blocks of 128 x 8-bit memory with a 2-wire serial inter-
face. Low-voltage design permits operation down to
1.7V, with maximum standby and active currents of
only 1 A and 1 mA, respectively. The 24AAXXXE48
also has a page write capability for up to 8 bytes of
data (16 bytes on the 24AA025E48). The
24AAXXXE48 is available in the standard 8-pin
SOIC, 5-lead SOT-23, and 6-lead SOT-23 packages.
• Compatible with EUI-48™ and EUI-64™
• Single Supply with Operation Down to 1.7V
• Low-Power CMOS Technology:
- Read current 1 mA, max.
- Standby current 1 A, max.
• 2-Wire Serial Interface, I2C™ Compatible
• Schmitt Trigger Inputs for Noise Suppression
• Output Slope Control to Eliminate Ground Bounce
• 100 kHz and 400 kHz Clock Compatibility
• Page Write Time 3 ms, typical
• Self-Timed Erase/Write Cycle
• Page Write Buffer:
