24AA025T-I/MS

Memory IC Overview

The Microchip Technology 24AA025T-I/MS 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 typical standby current of 1 μA and active read current of 1 mA. The device supports clock frequencies up to 400 kHz, providing a maximum access time of 900 ns at VCC ≥ 1.8V. It includes a 16-byte page write buffer and self-timed erase/write cycles with a maximum duration of 5 ms. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• I²C compatible 2-wire serial interface supporting 100 kHz and 400 kHz clock rates
• Low-power CMOS technology enabling operation down to 1.7V with minimal active and standby currents
• 16-byte page write buffer allowing efficient multi-byte data storage operations
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Industrial systems requiring non-volatile data retention
• Consumer electronics utilizing low-voltage power supplies
• Embedded controllers needing compact serial memory solutions

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' corresponds to tape and reel packaging requirements for automated assembly lines. Confirm that the 'I' designation aligns with the necessary industrial temperature range specifications (-40°C to +85°C). Ensure the MSOP package dimensions match the target PCB footprint constraints. Cross-reference the datasheet revision to confirm compatibility with existing design documentation.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application data logging or configuration storage. Choose the 24AA025 variant over the 24AA024 if hardware write protection via the WP pin is not required, as this version lacks the internal connection for that pin. Consider the MSOP package for space-constrained designs compared to larger SOIC or PDIP options.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial Electrically Erasable PROMs. It shares functional similarities with the 24AA024 but differs in write protection features. The family utilizes a standard I²C protocol, allowing multiple devices to be cascaded on a single bus using address pins A0, A1, and A2 for chip selection.
