24LC08BT-E/MNY

Memory IC Overview

The Microchip Technology 24LC08BT-E/MNY is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting maximum clock frequencies of 100 kHz at voltages below 2.5V and 400 kHz at 2.5V to 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports extended industrial temperature ranges from -40°C to +125°C. Key electrical characteristics include a maximum active read current of 1 mA and standby current of 5 µA. Data retention exceeds 200 years, with endurance rated for over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin to inhibit write operations when tied to VCC
• Page write buffer allowing up to 16 bytes of data storage before internal programming cycle initiation
• Schmitt trigger inputs on SDA and SCL lines for noise suppression and ground bounce elimination

Memory IC Applications

• Non-volatile data storage in embedded systems requiring hardware write protection
• Configuration parameter storage in industrial control devices operating at extended temperatures
• Serial address and identification data logging in I2C bus networks

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm the voltage range requirements match the 2.5V minimum specification for the 24LC08B series. Ensure compatibility with the 8-TDFN package dimensions for PCB layout. Check for any recent Product Change Notifications regarding assembly sites or materials.

Memory IC Selection Notes

Select this component when an 8-Kbit EEPROM is needed with extended temperature support up to 125°C. The 24LC08B series requires a minimum supply voltage of 2.5V, distinguishing it from the 24AA08 which supports lower voltages. Consider the TDFN package size constraints and the availability of the hardware write-protect feature for security-sensitive applications.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA08 and 24FC08, which differ primarily in supply voltage ranges and maximum clock speeds. The 24LC08B specifically targets applications requiring robust operation at standard 3.3V and 5V logic levels with extended thermal tolerance.

Memory IC Replacement Considerations

Direct substitutes within the same package and electrical specifications include other 24LC08B variants such as 24LC08BT-I/MNY for industrial temperature grades. Cross-family replacements like the 24AA08 offer lower voltage operation but may require level shifting if used in 2.5V-only systems.
