24LC08BT-E/SN

Memory IC Overview

The Microchip Technology 24LC08BT-E/SN is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz at VCC levels between 2.5V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and utilizes a standard 8-lead SOIC surface-mount package.

Memory IC Feature Summary

• Supports page write operations with a 16-byte buffer for efficient data transfer
• Includes hardware write-protect functionality via the WP pin to secure memory arrays
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating on single supply voltages
• Parameter retention in automotive electronics certified under AEC-Q100 standards

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the 8-lead SOIC package type. Confirm voltage specifications align with the 2.5V minimum requirement for the 24LC08B series, distinct from lower-voltage variants. Ensure compatibility with I2C bus pull-up resistor values appropriate for 400 kHz operation.

Memory IC Selection Notes

Select this component when application requirements demand extended temperature performance alongside standard I2C connectivity. The 8-lead SOIC package offers a balance of board space efficiency and thermal dissipation suitable for general-purpose surface mount designs. Consider the hardware write-protect feature if physical security against accidental overwrites is necessary for the target system.

Memory IC Part Context

This part belongs to the 24LC08B family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 devices but is distinguished by its specific voltage operating range and temperature rating. The 'E' suffix denotes the extended temperature grade, while '/SN' identifies the 8-lead SOIC package configuration.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages such as 24LC08BT-I/MS or 24LC08BT-E/MNY, provided the temperature and package constraints are met. Cross-family replacements like 24AA08 or 24FC08 require verification of voltage level compatibility and clock speed differences.
