24LC08BT-E/OT

Memory IC Overview

The Microchip Technology 24LC08BT-E/OT is an 8-Kbit (1024 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire serial interface compatible with I²C protocols. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz at these voltages, or 100 kHz when VCC is between 1.7V and 2.5V. The device includes a 16-byte page write buffer and hardware write-protect functionality via the WP pin. It is qualified for extended temperature ranges (-40°C to +125°C) and offers high endurance exceeding one million erase/write cycles with data retention greater than 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication with Schmitt trigger inputs for noise suppression.
• Features hardware write protection that inhibits all memory writes when the WP pin is tied to VCC.
• Includes a 16-byte page write buffer to optimize data transfer efficiency during write operations.
• Provides high reliability with over one million erase/write cycles and extensive data retention capabilities.

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage in embedded controllers
• Calibration data retention in sensor modules

Memory IC Procurement Notes

Verify the specific suffix 'E/OT' corresponds to the Extended temperature grade and TSSOP package type as defined in the official datasheet. Confirm that the operating voltage requirements align with the 2.5V minimum specification for the 24LC08B variant. Ensure compatibility with the host system's I²C bus timing constraints, particularly regarding rise/fall times and pull-up resistor values required for stable operation at 400 kHz.

Memory IC Selection Notes

Select this component when a non-volatile memory solution is required for storing small amounts of configuration or calibration data in space-constrained designs. The TSSOP package is suitable for surface-mount applications requiring moderate pin density. Consider the 2.5V minimum supply voltage constraint; if lower voltage operation down to 1.7V is necessary, alternative variants such as the 24AA08 or 24FC08 should be evaluated instead.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit I²C Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA08 and 24FC08, which differ primarily in operating voltage ranges and maximum clock speeds. The 24LC08B specifically targets applications requiring standard 2.5V to 5.5V operation with robust noise immunity features integrated into its CMOS technology.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages (e.g., SOIC, MSOP) or temperature grades (Industrial). Cross-family replacements like the 24AA08 offer wider voltage support but may require level shifting if the system operates below 2.5V. Verify pinout compatibility and electrical characteristics before substituting.
