Description

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. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25AA02E48 is available in the standard 8-lead SOIC and 6-lead SOT-23 packages.

The 25AA02E48 is designed as one kind of 2 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device that has some points of features: (1)Pre-programmed Globally Unique, 48-bit Node Address; (2)Compatible with EUI-48 and EUI-64; (3)10 MHz max. Clock Frequency; (4)256 x 8-bit Organization; (5)Write Page mode (up to 16 bytes); (6)Sequential Read; (7)Self-Timed Erase and Write Cycles (5 ms max.); (8)Block Write Protection: - Protect none, 1/4, 1/2 or all of array; (9)Pb-Free and RoHS Compliant.etc.

The 25AA02E48 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.

The absolute maximum ratings of the 25AA02E48 can be summarized as:(1)VCC: 6.5V;(2)All inputs and outputs w.r.t. VSS: -0.6V to VCC +1.0V;(3)Storage temperature: -65°C to 150°C;(4)Ambient temperature under bias: -40°C to 85°C;(5)ESD protection on all pins: 4 kV.
