24AA024-I/P

Memory IC Overview

The Microchip Technology 24AA024-I/P 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 with a maximum clock frequency of 400 kHz. The device includes hardware write protection via the WP pin, supports page writes up to 16 bytes, and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write-protect capability enabled by tying the WP pin to VCC
• I²C compatible bidirectional serial interface supporting multiple bus masters
• Internal address pointer for sequential read operations across memory boundaries
• Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in sensor modules
• Device identification and parameter backup in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'P' corresponds to the 8-lead PDIP package as specified in the datasheet. Confirm the temperature grade 'I' meets the -40°C to +85°C operational requirement. Ensure the application circuit provides adequate pull-up resistors for the SDA and SCL lines to support the required clock speeds within the 1.7V to 5.5V supply range.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution with hardware write protection is required. The 24AA024 differs from the 24LC024 by its lower minimum operating voltage of 1.7V compared to 2.5V. Choose the PDIP package for through-hole mounting applications requiring robust mechanical stability.

Memory IC Part Context

The 24AA024 is part of the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs. It shares functional similarities with the 24LC024 but distinguishes itself through a wider voltage operating range starting at 1.7V. The device utilizes a single block of 256 x 8-bit memory organization accessible via standard I²C protocols.

Memory IC Replacement Considerations

The 24LC024-I/P serves as a functional substitute if the system supply voltage remains above 2.5V. Other family members like the 24AA025 offer similar capacity but lack the hardware write-protect pin.
