24LC08BHT-E/OT

Memory IC Overview

The Microchip Technology 24LC08BHT-E/OT is an 8 Kbit (1 k x 8) Electrically Erasable PROM featuring a 2-Wire I2C compatible serial interface. It operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 400 kHz. The device utilizes Low-Power CMOS technology with a typical read current of 1 mA and standby current of 1 µA. It offers data retention exceeding 200 years and endurance of over 1 million erase/write cycles. The component is housed in a 5-lead SOT-23 package and is rated for an extended operating temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability allows locking the upper half of the memory array via the WP pin
• Integrated Schmitt trigger inputs and output slope control provide noise suppression and eliminate ground bounce
• Supports page write operations with a 16-byte buffer to enhance bus throughput efficiency

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial equipment needing reliable data logging under high temperature conditions
• Automotive electronics demanding robust memory solutions with extended thermal tolerance

Memory IC Procurement Notes

Verify that the ordering suffix correctly identifies the E-temperature grade (-40°C to +125°C) and the OT package style (SOT-23-5). Confirm the specific revision level matches the required datasheet version DS20002084B. Ensure compatibility with the target system's I2C bus voltage levels, as this variant requires a minimum of 2.5 V for proper operation.

Memory IC Selection Notes

Select this part when an automotive-grade or industrial-grade EEPROM is required alongside minimal board space constraints. The SOT-23-5 package provides a compact surface-mount solution compared to larger 8-pin alternatives. Consider the hardware write-protect feature if protecting critical data segments against accidental modification is necessary for the application design.

Memory IC Part Context

This component belongs to the 24LC08BH family of 8 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA08H but differs in minimum operating voltage requirements. The family includes various package options such as SOIC, TSSOP, and MSOP, with the HT suffix specifically denoting the SOT-23 form factor.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08BH variants with different packages like 24LC08BT-I/MS or 24LC08BHI-SN. Verify that replacement parts match the required temperature grade and voltage specifications before integration.
