24AA00T-I/OT

Memory IC Overview

The Microchip Technology 24AA00T-I/OT is a 128-bit (16 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.8V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, drawing typical read currents of 500 µA and standby currents of 100 nA. Packaged in a 5-lead SOT-23 format, it offers industrial temperature range operation from -40°C to +85°C with data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication protocol compatible with I²C bus standards
• Incorporates Schmitt trigger inputs and noise filtering for enhanced signal integrity on noisy buses
• Features self-timed erase/write cycles with internal address pointer management
• Includes output slope control mechanisms designed to minimize ground bounce effects

Memory IC Applications

• Storage of calibration values requiring small non-volatile memory capacity
• Retention of unique identification numbers for component tracking
• Archiving manufacturing information and configuration parameters

Memory IC Procurement Notes

Verify the specific suffix 'I/OT' confirms the Industrial temperature grade (-40°C to +85°C) and SOT-23 tape-and-reel packaging. Confirm that the 1.8V minimum operating voltage requirement aligns with the target system power rails. Ensure the I²C bus pull-up resistor values are appropriate for the 400 kHz maximum clock frequency specification.

Memory IC Selection Notes

Select this component when a minimal 128-bit storage footprint is required alongside strict low-power constraints. The 1.8V lower voltage limit distinguishes it from standard 2.5V or 4.5V variants suitable for higher voltage systems. The SOT-23 package is optimal for space-constrained surface-mount designs where through-hole options are unavailable.

Memory IC Part Context

This part belongs to the 24AA00 family of serial EEPROMs, which provides basic non-volatile storage solutions. It shares architectural similarities with the 24LC00 and 24C00 series but differs primarily in its minimum operating voltage threshold. The device serves as a foundational memory solution for simple embedded applications needing persistent data storage without complex interface requirements.

Memory IC Replacement Considerations

Direct functional substitutes within the same package include the 24AA00T-E/OT for extended automotive temperature ranges. Cross-brand equivalents may require verification of I²C timing compatibility and voltage level shifting capabilities.
