24LC08B/SN

Memory IC Overview

The Microchip Technology 24LC08B/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, supporting a maximum clock frequency of 400 kHz when operating within the 2.5V to 5.5V supply voltage range. The device utilizes low-power CMOS technology, ensuring standby current remains at or below 1 µA and active read current does not exceed 1 mA. It operates reliably across industrial temperatures from -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard two-wire serial bus protocol
• Includes hardware write protection controlled by the WP pin to inhibit write operations
• Features Schmitt trigger inputs and noise filtering for reliable operation on noisy buses
• Provides a 16-byte page write buffer to optimize data transfer efficiency

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing I2C communication interfaces
• Automotive applications meeting AEC-Q100 qualification standards
• Embedded devices needing secure configuration parameter retention

Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Confirm RoHS compliance status and ensure the component matches the required voltage specifications for your application design. Check for any recent Product Change Notifications that may affect availability or manufacturing location.

Memory IC Selection Notes

Select this component when an 8-Kbit capacity is sufficient for system requirements. Ensure the host controller supports the I2C protocol and can handle the 400 kHz clock speed. Verify that the 2.5V minimum supply voltage aligns with the system power rails. Consider the 8-lead SOIC package dimensions for PCB layout constraints.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs, which also includes the 24AA08 and 24FC08 variants. While sharing similar memory architecture and interface protocols, these variants differ in minimum operating voltage and maximum clock frequency capabilities. The 24LC08B specifically targets applications requiring operation down to 2.5V with 400 kHz support.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages such as 24LC08B-I/MS or 24LC08B-E/ST. Cross-referencing with 24AA08 or 24FC08 requires verifying voltage and speed compatibility. Always consult the manufacturer's datasheet for electrical characteristic comparisons before substitution.
