24LC08B-E/MC

Memory IC Overview

The Microchip Technology 24LC08B-E/MC is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial I2C interface with a maximum clock frequency of 400 kHz for supply voltages between 2.5V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and supports a supply voltage range of 2.5V to 5.5V. It includes a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I2C bus protocols.
• Includes a 16-byte page write buffer to optimize data transfer efficiency during write operations.
• Features hardware write protection that inhibits all write operations when the WP pin is tied to VCC.
• Equipped with Schmitt trigger inputs and filter circuits on SDA and SCL pins to suppress noise spikes.

Memory IC Applications

• Data logging in industrial control systems requiring extended temperature stability
• Configuration storage in automotive electronic modules
• Parameter retention in consumer electronics operating at 2.5V or higher

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the Extended temperature rating (-40°C to +125°C) aligns with system environmental requirements. Ensure the supply voltage constraints (2.5V minimum) are compatible with the host controller logic levels before finalizing procurement.

Memory IC Selection Notes

Select this component when an 8-Kbit non-volatile memory solution is needed with I2C connectivity. The Extended temperature variant is suitable for harsh environments where standard Industrial grade parts may fail. Consider the 8-lead MSOP package for space-constrained surface mount designs requiring robust thermal performance.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 but differs in voltage specifications and clock speed capabilities. The 24LC08B specifically targets applications requiring operation down to 2.5V, distinguishing it from lower-voltage or higher-speed variants within the same documentation scope.

Memory IC Replacement Considerations

Direct replacements include other 24LC08B variants with different packages such as 24LC08B-I/MS or 24LC08B/SN, provided the temperature grade and voltage requirements match. Cross-family substitutes like the 24AA08 require verification of the lower 1.7V operating capability and potential interface timing differences.
