24AA04-I/SN

Memory IC Overview

The Microchip Technology 24AA04-I/SN is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz at VCC ≥ 2.5V, and 100 kHz when VCC is between 1.7V and 2.5V. The device supports industrial temperature operation from -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Features hardware write protection via the WP pin to inhibit memory writes when tied high
• Includes a 16-byte page write buffer for efficient data transfer operations
• Incorporates Schmitt trigger inputs and noise filtering for reliable bus communication
• Provides output slope control to minimize ground bounce during switching

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules
• Device identification and serial number storage

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'SN' denotes the 8-lead SOIC package. Confirm RoHS compliance status as required by project specifications. Ensure the ordering quantity matches the manufacturer's standard tube packaging configuration for this specific part variant.

Memory IC Selection Notes

Select this component when a low-voltage EEPROM with I²C compatibility is required for industrial environments. It is suitable for applications needing hardware write protection and moderate speed access. Consider alternative packages like MSOP or TSSOP if board space constraints differ from the SOIC footprint requirements.

Memory IC Part Context

This device belongs to the 24XX04 family of 4-Kbit serial EEPROMs, which also includes the 24LC04B and 24FC04 variants. While sharing similar functional architectures and interfaces, these models differ in minimum operating voltage and maximum clock frequency specifications. The 24AA04 specifically targets low-voltage industrial applications.

Memory IC Replacement Considerations

The 24AA04T-I/SN serves as a tape-and-reel replacement for the same electrical and functional specifications. Other family members such as the 24LC04B or 24FC04 may function as substitutes but require verification of voltage and speed compatibility.
