24LC02BH-I/SN

Memory IC Overview

The Microchip Technology 24LC02BH-I/SN is a 2 Kbit (256 x 8) serial EEPROM featuring an I2C-compatible two-wire interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write protection for the upper half of the memory array (addresses 80h-FFh) via the WP pin. It utilizes low-power CMOS technology with a maximum active read current of 1 mA and standby current of 1 µA. The component is housed in an 8-lead SOIC package and is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection mechanism inhibits write operations to the upper half of the memory array when the WP pin is tied high.
• Integrated Schmitt trigger inputs on SDA and SCL lines provide noise suppression and spike filtering for reliable data transmission.
• Supports page write operations utilizing an 8-byte buffer to improve bus throughput efficiency.
• Includes acknowledge polling capability to allow the host to determine when internal write cycles are complete.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade and package type, as variations exist within the 24LC02BH family. Confirm compliance with RoHS directives if applicable to your manufacturing process. Ensure the specific revision level aligns with your design requirements. Cross-reference the manufacturer's latest datasheet for any potential product change notifications or lifecycle status updates before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution with hardware write protection is required. It is suitable for applications needing I2C connectivity with standard voltage levels between 2.5V and 5.5V. Consider the industrial temperature range if the environment exceeds standard commercial limits. Verify that the 8-byte page write buffer meets the system's data throughput needs.

Memory IC Part Context

This part belongs to the 24XX02H series of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA02H but differs in minimum operating voltage specifications. The series is designed for low-power applications requiring reliable data retention and simple serial interface integration.

Memory IC Replacement Considerations

Direct replacements include other variants within the 24LC02B or 24LC02BH families, provided they match the package and temperature rating. Ensure substitute parts support the same I2C protocol and voltage ranges. Verify pin compatibility for SOIC-8 packages.
