24LC08B/ST

Memory IC Overview

The Microchip Technology 24LC08B/ST 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 maximum clock frequencies of 100 kHz at voltages below 2.5V and 400 kHz at 2.5V to 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum standby current of 3 µA and a maximum operating current of 3 mA.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin allows for complete memory array protection when tied to VCC.
• Integrated Schmitt trigger inputs and filter circuits provide noise suppression on SDA and SCL lines.
• Supports page write operations with a 16-byte buffer to enhance bus throughput efficiency.
• Includes acknowledge polling functionality to determine internal write cycle completion status.

Memory IC Applications

• Data logging in industrial control systems requiring non-volatile storage
• Configuration parameter storage in embedded microcontroller designs
• Calibration data retention in sensor interfaces

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets RoHS compliance standards for your manufacturing process. Ensure that the supply voltage requirements align with the system design constraints before procurement.

Memory IC Selection Notes

Select this component for applications requiring low-power operation and reliable non-volatile data retention. Consider the 16-byte page write buffer for efficient data handling. Evaluate the hardware write-protect feature if security against accidental overwrites is critical for the application environment.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA08 and 24FC08, which differ primarily in supply voltage ranges and maximum clock frequencies. The 24LC08B specifically targets standard 2.5V to 5.5V operational environments.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC08B-I/MS and 24LC08B-E/ST, provided the package style and temperature grade match the design requirements. Cross-family replacements like the 24AA08 require verification of voltage compatibility.
