24AA04T-I/MS

Memory IC Overview

The Microchip Technology 24AA04T-I/MS is a 4-Kbit (512 x 8) serial EEPROM featuring an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz at voltages above 2.5V, or 100 kHz below that threshold. The device utilizes an MSOP-8 surface-mount package and includes a 16-byte page write buffer with a maximum write cycle time of 5 ms. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V with minimal active and standby currents.
• Integrated hardware write-protect capability via the WP pin to secure memory data against unauthorized modifications.
• Schmitt trigger inputs and output slope control designed to suppress noise and eliminate ground bounce during bus operations.

Memory IC Applications

• Data logging in battery-powered portable devices
• Configuration storage for microcontroller systems
• Parameter retention in industrial instrumentation

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'MS' denotes the MSOP-8 package. Confirm the 'T' indicates tape-and-reel packaging suitable for automated assembly. Ensure the source documentation explicitly lists this exact part number configuration before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a low-voltage EEPROM is required for space-constrained designs using surface-mount technology. The MSOP-8 package offers a compact footprint compared to through-hole alternatives. Ensure the system design accommodates the 1.7V minimum operating voltage and provides appropriate pull-up resistors for the I²C bus lines to maintain signal integrity.

Memory IC Part Context

This device belongs to the 24XX04 family of 4-Kbit serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but varies in voltage ranges, speed grades, and package options. The 24AA04 variant specifically targets low-voltage applications requiring robust noise immunity and long-term data retention capabilities.

Memory IC Replacement Considerations

Direct substitutes include other 24AA04 variants in different packages such as 24AA04T-I/MC (DFN) or 24AA04T-I/SN (SOIC). Cross-family replacements like 24LC04B are compatible electrically but require a minimum supply voltage of 2.5V, which may not suit all low-voltage designs.
