24AA024-I/SN

Memory IC Overview

The Microchip Technology 24AA024-I/SN is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and features a 2-wire I²C compatible interface with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, offering typical standby current of 1 μA and active read current of 1 mA. It supports hardware write protection via the WP pin and includes Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Hardware write-protect capability enabled by tying the WP pin to VCC
• Supports cascading up to eight devices on the same bus using address pins A0, A1, and A2
• Includes a 16-byte page write buffer for efficient data transfer
• Features Schmitt trigger inputs and output slope control to eliminate ground bounce

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Calibration data retention in consumer electronics
• Parameter storage in automotive applications

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 'SN' designation indicates an 8-lead SOIC package. Confirm the temperature grade corresponds to the Industrial range (-40°C to +85°C). Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires hardware-level write protection to prevent accidental data modification. It is suitable for designs needing I²C connectivity with minimal pin count. Consider the 1.7V minimum operating voltage for low-power battery-operated applications. Verify that the 400 kHz clock speed meets the system's communication timing requirements.

Memory IC Part Context

This device belongs to the 24AA024/24LC024 family of 2 Kbit serial EEPROMs. It shares functional similarities with the 24LC024 but differs in its lower minimum operating voltage of 1.7V compared to the 2.5V requirement of the LC variant. Both variants support the same I²C interface and hardware write protection features, making them interchangeable in many designs provided the voltage constraints are met.

Memory IC Replacement Considerations

The 24LC024-I/SN is a direct functional substitute, though it requires a minimum supply voltage of 2.5V instead of 1.7V. Other members of the 24AA02x series may offer different capacities or package options.
