Microchip 2Kbit I2C EEPROM with EUI-48 Node Identity SOT-23-5

The Microchip 2Kbit I2C EEPROM with EUI-48 Node Identity is a compact 2Kbit serial EEPROM memory device supplied in a 5-pin SOT-23 surface-mount package. It is preprogrammed with a unique 48-bit EUI-48 node address, providing a ready-made hardware identity for networked devices.

Overview

Organised as two blocks of 128 x 8-bit memory, the device uses a two-wire I2C serial interface for communication. Its low-voltage design supports operation from 1.7 V to 5.5 V, making it suitable for a range of logic families and battery-powered applications. The small package suits dense electronic designs where board space is limited.

Key Features

• Page Write Capability: Writes up to 8 bytes of data in a single operation, with a typical page write time of 3 ms.
• High-Speed Interface: Operates at a maximum clock frequency of 400 kHz.
• Schmitt Trigger Inputs: Low-power CMOS design with Schmitt trigger inputs and output slope control to help suppress noise and limit ground bounce.
• Endurance and Retention: Rated for more than 1 million erase/write cycles and data retention greater than 200 years.
• Unique Identifier: Factory-set, unique 48-bit EUI-48 node address that removes the need for manual configuration.
• Wide Temperature Range: Operates across an industrial temperature range of -40 °C to +85 °C.

Power Consumption

The device has a maximum standby current of 1 µA and a maximum active current of 1 mA.

Choose this EEPROM when you need compact, non-volatile memory with a preprogrammed EUI-48 node identity and a standard two-wire I2C interface.
