24LC08B-E/MS

Memory IC Overview

The Microchip Technology 24LC08B-E/MS 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 clock frequencies up to 400 kHz at supply voltages between 2.5V and 5.5V. The device utilizes low-power CMOS technology, ensuring standby current remains at or below 5 µA in extended temperature conditions. It includes a 16-byte page write buffer and hardware write protection via the WP pin.

Memory IC Feature Summary

• Supports bidirectional data transmission over a two-wire serial bus using standard I2C protocol
• Includes Schmitt trigger inputs and filter circuits on SDA and SCL pins for noise suppression
• Features hardware write protection that inhibits write operations when the WP pin is tied to VCC
• Provides acknowledge polling capability to determine internal write cycle completion

Memory IC Applications

• Data logging in industrial control systems requiring non-volatile storage
• Configuration parameter storage in consumer electronics operating within extended temperature ranges
• Calibration data retention in automotive-grade embedded applications

Memory IC Procurement Notes

Verify the specific ordering suffix corresponds to the MSOP package type and Extended temperature grade. Confirm RoHS compliance status matches current manufacturing standards. Ensure the selected variant aligns with the required voltage range of 2.5V to 5.5V for proper functionality.

Memory IC Selection Notes

Select this component when operation within an extended ambient temperature range of -40°C to +125°C is required. Choose this part over Industrial grade variants if the application environment exceeds standard commercial limits. Ensure the system power supply remains stable between 2.5V and 5.5V to maintain specified timing parameters.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 but is distinguished by its minimum operating voltage of 2.5V. The E suffix denotes the Extended temperature rating, differentiating it from the Industrial grade counterpart.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages such as SOIC or TSSOP. Cross-reference with 24AA08 devices only if the system voltage supports the lower 1.7V threshold.
