24LC02BT-I/OT

Memory IC Overview

The Microchip Technology 24LC02BT-I/OT is a 2-Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible two-wire 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 OT package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer using a standard two-wire serial bus protocol with start and stop conditions.
• Includes an 8-byte page write buffer to optimize data throughput during sequential write operations.
• Provides hardware-based write protection by connecting the WP pin to VCC to inhibit memory writes.
• Features Schmitt trigger inputs on SCL and SDA lines to suppress noise spikes and ensure signal integrity.

Memory IC Applications

• Non-volatile data storage in industrial control systems
• Configuration parameter retention in embedded devices
• Calibration data logging in sensor modules

Memory IC Procurement Notes

Verify that the specific ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) as defined in the manufacturer's datasheet. Confirm the 'OT' suffix matches the required physical package type. Ensure supply chain sources provide documentation confirming RoHS compliance and AEC-Q100 qualification status if automotive reliability is required.

Memory IC Selection Notes

Select this component when a 2-Kbit non-volatile memory solution is needed with low standby current consumption. It is suitable for applications requiring hardware write protection and operation at voltages starting from 2.5V. Consider alternative variants like the 24AA02 or 24FC02 only if lower voltage operation down to 1.7V or higher clock speeds are necessary.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs, which shares functional similarities with the 24AA02 and 24FC02 models. While they share the same memory organization and interface protocols, they differ in minimum operating voltage and maximum clock frequency specifications. The 24LC02B variant specifically requires a minimum supply voltage of 2.5V.

Memory IC Replacement Considerations

Direct substitutes include other packages of the same electrical specification, such as 24LC02BT-I/SN or 24LC02BT-I/MC. Cross-family replacements like 24AA02 or 24FC02 require verification of voltage compatibility and clock speed limits.
