24LC02BHT-I/OT

Memory IC Overview

The Microchip Technology 24LC02BHT-I/OT 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 a 5-lead SOT-23 package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Schmitt trigger inputs on SDA and SCL lines for enhanced noise suppression
• Internal self-timed erase/write cycles with automatic address pointer incrementation

Memory IC Applications

• Embedded systems requiring persistent storage for configuration parameters
• Industrial control units needing non-volatile data retention under varying temperatures
• Low-power consumer electronics utilizing I²C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOT-23 package and Industrial temperature grade. Confirm compliance with RoHS directives and ensure the supply chain provides valid traceability documentation. Cross-reference the manufacturer part number against official datasheets to validate electrical specifications before integration.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small-capacity non-volatile storage. The SOT-23 package minimizes board space compared to larger SOIC or PDIP options. Ensure the application voltage remains above 2.5V to maintain full 400 kHz operational speed without frequency reduction.

Memory IC Part Context

This device belongs to the 24LC02BH series, which integrates half-array write protection capabilities not found in standard variants. It shares the core architecture with the 24AA02H but differs in minimum operating voltage requirements. The series is designed for applications demanding high endurance and long-term data retention in space-constrained environments.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02BH variants in different packages such as 24LC02BT-I/SN or 24LC02BT-I/MC. Verify package compatibility and voltage thresholds when replacing with 24AA02H models, as their lower voltage operation may require circuit adjustments.
