Detailed Description

2 Kbit (256-byte) I2C serial EEPROM from the Microchip 24LC02B family. Industrial temperature grade. SOP-8 package. Non-volatile memory for storing small configuration data, IDs, calibration values, and parameters. Uses a two-wire I2C bus, supports Standard and Fast-mode operation. Includes hardware Write-Protect and address pins for up to eight devices on the same bus.

Key Features

2 Kbit capacity organized as 256 x 8 bytes

I2C two-wire interface up to 400 kHz

Industrial temperature range −40°C to +85°C

Operating voltage typically 2.5 V to 5.5 V for 24LC series

Hardware Write-Protect (WP pin)

Device address pins A0, A1, A2 for easy multi-device stacking

Self-timed write cycle, typical 5 ms

Low standby current and low power operation

High endurance, up to 1,000,000 write cycles typical

Long data retention, up to 200 years typical

ESD-protected, Schmitt-trigger inputs, noise-tolerant I2C pins

Key Advantages

Simple, reliable non-volatile storage for parameters and IDs

Easy integration with any MCU supporting I2C

Low power, small footprint, and cost-effective

Hardware write protection adds safety against accidental writes

Multiple address pins let you use several EEPROMs on one bus

Mature, widely used device with robust ecosystem and support
