24AA024T-I/SN

Memory IC Overview

The Microchip Technology 24AA024T-I/SN is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write protection via the WP pin, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead SOIC package and rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write protection enabled by tying the WP pin high
• 16-byte page write buffer for efficient data storage
• Schmitt trigger inputs with spike suppression for noise immunity
• Supports cascading up to eight devices on a single bus

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Embedded controllers needing configuration data retention
• Low-power battery-operated devices utilizing wide voltage range
• Data logging applications benefiting from high endurance cycles

Memory IC Procurement Notes

Verify that the specific ordering suffix 'T' corresponds to tape-and-reel packaging if required for automated assembly processes. Confirm the 'I' temperature grade matches the operational environment limits of -40°C to +85°C. Ensure the SOIC package dimensions align with the target PCB footprint. Cross-reference the datasheet revision to confirm compatibility with existing firmware protocols.

Memory IC Selection Notes

Select this component when hardware-level write protection is mandatory for data integrity. The 24AA024 differs from the 24LC024 by supporting lower voltages down to 1.7V. Choose this part over the 24AA025 if the physical WP pin is required for circuit design. Verify that the 400 kHz speed requirement is met within the specific operating voltage constraints defined in the AC characteristics.

Memory IC Part Context

This device belongs to the Microchip 24AA024/24LC024 family of 2 Kbit serial EEPROMs. It shares functional similarities with the 24AA025 but distinguishes itself through the inclusion of a dedicated hardware write-protect pin. The 'SN' designation indicates an 8-lead Small Outline Integrated Circuit package suitable for surface mount technology applications.

Memory IC Replacement Considerations

The 24AA024T-I/SNG serves as a direct replacement variant offering identical electrical specifications and functionality while utilizing tape-and-reel packaging instead of tube.
