24AA025T-I/MC

Memory IC Overview

The Microchip Technology 24AA025T-I/MC is a 2 Kbit (256 x 8) serial EEPROM utilizing 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 features a 16-byte page write buffer, self-timed erase/write cycles with a maximum duration of 5 ms, and high endurance exceeding one million write cycles. It includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address pins A0, A1, and A2.
• Includes hardware write protection capabilities via the WP pin for secure data storage.
• Features low-power CMOS technology with typical standby current of 1 μA and active read current of 1 mA.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple packages including DFN, MSOP, and TSSOP. Confirm the temperature grade 'I' corresponds to the industrial range (-40°C to +85°C). Ensure the datasheet revision aligns with the manufacturing date code for accurate electrical specifications.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application requirements. Choose this variant over the 24LC025 if operation below 2.5V is necessary, as the 24LC025 requires a minimum of 2.5V. Consider the 24AA024 if hardware write protection is mandatory, as the 24AA025 lacks internal connection to the WP pin.

Memory IC Part Context

This component belongs to the 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares functional similarities with other members but differs in voltage range and write protection availability. The 'T' suffix indicates tape and reel packaging, while 'MC' denotes the 8-lead DFN package.
