24LC02BT-I/MC

Memory IC Overview

The Microchip Technology 24LC02BT-I/MC 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 an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead DFN package with exposed pad and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Includes an 8-byte page write buffer to optimize data transfer efficiency
• Provides hardware-based write protection to prevent unauthorized memory modifications

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration parameter retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'MC' corresponds to the 8-lead DFN package configuration. Confirm the 'I' designation indicates the industrial temperature grade (-40°C to +85°C). Ensure the supply voltage meets the minimum 2.5V requirement specified for the 24LC02B series. Check datasheet revisions for any recent manufacturing or assembly changes.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small-scale non-volatile storage. The 24LC02BT-I/MC is suitable for designs needing hardware write protection and low standby current. Compare against the 24AA02 if operation below 2.5V is necessary, as the 24LC02B series requires a minimum of 2.5V.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs from Microchip Technology. The family includes variants like the 24AA02 and 24FC02, which differ primarily in operating voltage ranges and maximum clock speeds. The 24LC02B specifically targets applications requiring stable operation at voltages starting from 2.5V.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants in different packages such as 24LC02B/SN (SOIC) or 24LC02B/MC (MSOP), provided the pinout and electrical characteristics remain identical.
