24LC08B-E/SN

Memory IC Overview

The Microchip Technology 24LC08B-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 serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. It includes hardware write-protect capabilities, Schmitt trigger inputs for noise suppression, and output slope control. The component is rated for extended temperature operation from -40°C to +125°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol.
• Includes hardware write-protect functionality controlled by the WP pin.
• Features Schmitt trigger inputs and filter circuits for noise suppression.
• Provides output slope control to eliminate ground bounce effects.

Memory IC Applications

• Data logging in industrial environments requiring extended temperature ranges.
• Configuration storage for embedded systems operating at low voltages.
• Parameter retention in consumer electronics utilizing I2C interfaces.

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the SOIC package type. Confirm compatibility with the target system's I2C bus voltage levels, noting the minimum operating voltage is 2.5V. Ensure the design accounts for the hardware write-protect pin requirements if data integrity during writes is critical.

Memory IC Selection Notes

Select this component when extended temperature performance is required alongside standard I2C connectivity. It is suitable for applications needing non-volatile storage with high endurance and long data retention. Consider the 8-lead SOIC package for surface mount assembly constraints. Verify that the system power supply remains within the 2.5V to 5.5V range to ensure proper operation.

Memory IC Part Context

This part belongs to the 24LC08B series of 8-Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 devices but differs in voltage specifications and maximum clock frequency. The series is designed for low-power applications requiring reliable data storage in compact packages.

Memory IC Replacement Considerations

Direct replacements include other 24LC08B variants with different temperature grades or packages, such as 24LC08B-I/SN for industrial temperatures. Cross-family substitutes like 24AA08 or 24FC08 require verification of voltage compatibility and clock speed limitations.
