24LC08BHT-E/MNY

Memory IC Overview

The 24LC08BHT-E/MNY is an 8 Kbit Electrically Erasable PROM manufactured by Microchip Technology. It features a 2-Wire Serial Interface compatible with I2C protocols and supports clock frequencies up to 400 kHz. The device operates within a voltage range of 2.5 V to 5.5 V and is designed for automotive applications with an extended temperature range of -40°C to +125°C. It includes hardware write-protect capabilities for half the array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Hardware write-protect mechanism secures the upper half of the memory array against unintended modifications.
• Schmitt trigger inputs combined with filter circuits provide enhanced noise spike suppression on serial data lines.
• Output slope control circuitry minimizes ground bounce effects during high-speed switching operations.

Memory IC Applications

• Automotive electronic systems requiring reliable non-volatile data storage under extreme temperatures.
• Industrial control units utilizing I2C communication for configuration parameter retention.
• Embedded devices needing protected memory sectors for critical system settings.

Memory IC Procurement Notes

Verify that the specific suffix E/MNY corresponds to the Automotive grade (-40°C to +125°C) and SOT-23-5 package as defined in official Microchip documentation. Confirm RoHS compliance status and ensure the ordering code matches the exact temperature and packaging requirements for your design. Cross-reference the datasheet revision to validate electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component when automotive-grade reliability and extended temperature operation are required alongside standard I2C interface compatibility. Ensure the application voltage remains above 2.5 V to maintain specified performance levels. Consider the half-array write-protect feature if security for specific memory regions is necessary without software overhead.

Memory IC Part Context

This part belongs to the 24LC08BH family of 8 Kbit serial EEPROMs from Microchip Technology. It shares core architectural features with industrial variants but differs in temperature rating and package type. The 'E' suffix denotes the automotive temperature grade, while '/MNY' indicates the specific surface-mount package configuration available for compact designs.

Memory IC Replacement Considerations

Direct replacements include other 24LC08BH variants with matching I2C interfaces and voltage ranges. Verify pinout compatibility, particularly regarding the unused A0-A2 pins and WP functionality. Ensure substitute parts meet the same automotive temperature specifications if operating conditions require it.
