24AA04T-I/OT

Memory IC Overview

The Microchip Technology 24AA04T-I/OT is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It features a Two-Wire Serial Interface compatible with I²C protocols and operates on a single supply voltage ranging from 1.7V to 5.5V. The device supports a maximum clock frequency of 400 kHz at voltages above 2.5V, reducing to 100 kHz when the supply voltage is between 1.7V and 2.5V. It utilizes Low-Power CMOS technology, ensuring low standby and active current consumption.

Memory IC Feature Summary

• Low-voltage operation down to 1.7V for extended power efficiency
• I²C compatible bidirectional serial interface with Schmitt trigger inputs
• Hardware write-protect capability via the WP pin
• High reliability with over one million erase/write cycles

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter retention in battery-powered devices

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range compatibility with the target system's power supply rails. Ensure the I²C bus pull-up resistor values align with the operating frequency and voltage level to maintain signal integrity.

Memory IC Selection Notes

Select this component for applications requiring non-volatile data storage with minimal power consumption. The 24AA04T-I/OT is suitable for designs needing hardware write protection and robust noise immunity through Schmitt triggers. Consider the page write buffer size when optimizing write throughput for sequential data operations.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs, which includes variants like the 24LC04B and 24FC04. These devices share similar architectural features but differ in voltage ranges and maximum clock frequencies. The 24AA04 specifically targets general-purpose applications with its wide voltage tolerance and standard I²C speed capabilities.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC04B and 24FC04, provided their specific voltage and speed requirements match the design constraints. Verify package pinout compatibility before swapping.
