24LC01B-I/SNG

Memory IC Overview

The Microchip Technology 24LC01B-I/SNG is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) utilizing a 2-wire I²C serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It supports industrial temperature ranges (-40°C to +85°C), offers over one million erase/write cycles, and retains data for more than 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication compatible with standard I²C protocols
• Includes an 8-byte page write buffer to optimize data transfer efficiency
• Provides hardware-based write protection through the dedicated WP pin
• Features Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Storage of configuration parameters and system settings in embedded devices
• Logging operational data and sensor calibration values
• Backup storage for security keys or user preferences
• Non-volatile memory expansion for microcontroller systems

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the SOIC-8 package as specified in the datasheet. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the voltage supply aligns with the 2.5V minimum requirement specific to the 24LC01B series rather than lower voltage variants.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for non-volatile data retention. Choose the 24LC01B specifically if the operating voltage must be at least 2.5V, distinguishing it from the 24AA01 which supports lower voltages. The SOIC-8 package is suitable for surface mount applications requiring standard footprint dimensions.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA01 and 24FC01, differentiated primarily by voltage ranges and clock speeds. The 24LC01B represents the standard low-voltage CMOS version optimized for general-purpose industrial applications.

Memory IC Replacement Considerations

Direct substitutes within the same package include the 24LC01B-I/ST (TSSOP-8) or 24LC01B-I/P (PDIP-8). Cross-family replacements such as the 24AA01 require verification of voltage compatibility, as the 24AA01 supports operation down to 1.7V.
