24LC02B-I/SNG

Memory IC Overview

The Microchip Technology 24LC02B-I/SN is a 2-Kbit (256 x 8) serial EEPROM utilizing an I²C interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features a maximum access time of 900 ns and a page write time of 5 ms. It is housed in an 8-lead SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin
• Schmitt trigger inputs for noise suppression
• Output slope control to eliminate ground bounce
• Self-timed erase/write cycles with acknowledge polling

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics compliant with AEC-Q100 standards
• Consumer devices needing low-power configuration retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple form factors. Confirm the temperature grade suffix corresponds to the intended operating environment. Ensure the voltage rating aligns with the system power supply constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 2-Kbit capacity is sufficient for application requirements. Choose the SN suffix specifically for surface-mount 8-lead SOIC packaging needs. Consider the 2.5V minimum operating voltage constraint compared to lower-voltage alternatives if system power rails are tight.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA02 and 24FC02 models but differs in minimum operating voltage and maximum clock frequency specifications. The family utilizes a standardized two-wire serial interface protocol for efficient data communication.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different package suffixes such as PDIP or MSOP. Cross-family replacements like the 24AA02 offer lower voltage operation but may require voltage level adjustments.
