24LC08BHT-I/MS

Memory IC Overview

The Microchip Technology 24LC08BHT-I/MS is an 8 Kbit Electrically Erasable PROM organized as four blocks of 256 x 8-bit memory. It features a 2-wire serial interface compatible with I²C™, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. Key electrical characteristics include a maximum active read current of 1 mA and a standby current of 1 µA. It offers data retention exceeding 200 years and endurance of over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array (addresses 200h-3FFh) via the WP pin
• Integrated page write buffer allowing storage of up to 16 bytes before internal programming cycle initiation
• Schmitt trigger inputs and noise filter circuits on SCL and SDA lines for enhanced signal integrity

Memory IC Applications

• Embedded systems requiring persistent storage for configuration parameters
• Data logging applications utilizing sequential read operations
• Industrial control units needing hardware-level write protection for critical memory segments

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging when sourcing this specific variant. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the MSOP package dimensions align with the target PCB footprint constraints. Cross-reference the datasheet revision date to confirm compatibility with existing design specifications.

Memory IC Selection Notes

Select this component when half-array write protection is mandatory for security or stability. The MSOP package is suitable for space-constrained surface-mount designs. Verify that the system power supply remains within the 2.5 V to 5.5 V operational window. Consider the 400 kHz clock speed if higher bus throughput is required compared to standard 100 kHz operation.

Memory IC Part Context

This part belongs to the 24AA08H/24LC08BH family of 8 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members of the series but is distinguished by its specific voltage range and package type. The 'L' in the model number indicates the 2.5 V minimum operating voltage, differentiating it from the 'AA' variants which support lower voltages.

Memory IC Replacement Considerations

Direct replacements must maintain the 8 Kbit capacity, I²C interface, and MSOP-8 package. Verify that substitute parts support the same 2.5 V to 5.5 V supply range and industrial temperature grade.
