24AA025T-I/OT

Memory IC Overview

The Microchip Technology 24AA025T-I/OT is a 2 Kbit (256 x 8) serial electrically erasable PROM featuring an I2C-compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies of up to 400 kHz. The device utilizes low-power CMOS technology with typical standby current of 1 μA and read current of 1 mA. It includes a 16-byte page write buffer, Schmitt trigger inputs for noise suppression, and output slope control. The component is housed in a 6-lead SOT-23 package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address pins A0, A1, and A2 for contiguous memory expansion.
• Includes a 16-byte page write buffer that allows multiple data bytes to be transmitted before initiating the internal write cycle.
• Features Schmitt trigger inputs and VCC threshold detection to suppress noise spikes and disable erase/write logic during low voltage conditions.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices
• Industrial control applications

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the 'I' designation aligns with the specified industrial temperature range requirements for the target application environment.

Memory IC Selection Notes

Select this component when a compact 6-lead SOT-23 package is necessary for space-constrained designs. Ensure the system design accommodates the absence of a hardware write-protect pin, as the 24AA025 variant does not include this feature compared to the 24AA024 model.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial EEPROMs. While functionally similar to other members, it is distinguished by its availability in the 6-lead SOT-23 package and the lack of a hardware write-protect pin, differentiating it from the 24AA024 which includes WP functionality.

Memory IC Replacement Considerations

The 24AA024T-I/OT serves as a direct functional substitute if hardware write protection via the WP pin is required. Other compatible replacements within the family include the 24LC025 series, though these require a minimum operating voltage of 2.5V rather than 1.7V.
