24AA16T-E/MS

Memory IC Overview

The Microchip Technology 24AA16T-E/MS is a 16-Kbit (2K x 8) serial EEPROM utilizing an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V, with a maximum clock frequency of 400 kHz at voltages above 2.5V and 100 kHz below that threshold. The device features a 16-byte page write buffer, hardware write protection via the WP pin, and supports industrial temperature ranges (-40°C to +125°C). Packaged in an 8-lead MSOP format, it offers high endurance exceeding one million erase/write cycles and data retention for over 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Includes a 16-byte page write buffer to optimize data transfer efficiency
• Provides hardware-based write protection through the dedicated WP pin
• Features Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Non-volatile data storage in embedded systems requiring low power consumption
• Configuration parameter storage in consumer electronics devices
• Calibration data retention in industrial instrumentation
• Device identification and tracking information in manufacturing equipment

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates extended temperature range operation up to +125°C and confirm the 'MS' designation corresponds to the 8-lead MSOP package. Ensure compatibility with system voltage levels, noting reduced clock speeds below 2.5V. Check for RoHS compliance status and confirm lead-free marking requirements for assembly processes.

Memory IC Selection Notes

Select this component when a small footprint non-volatile memory solution is required for applications operating within the extended industrial temperature range. Consider the 16-byte page write capability for efficient data handling. Verify that the I²C bus speed requirements align with the 400 kHz limit at higher voltages or the 100 kHz limit at lower voltages. Evaluate the need for hardware write protection if security against accidental writes is critical.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which includes variants like the 24LC16B and 24FC16. While sharing similar memory organization and interface protocols, differences exist in minimum operating voltage and maximum clock frequency. The 24AA16 variant specifically supports operation down to 1.7V, distinguishing it from parts requiring higher minimum voltages.

Memory IC Replacement Considerations

Direct substitutes include other 24AA16 variants with different packages such as 24AA16-I/MS or 24AA16-E/MC. Cross-family replacements like 24LC16B or 24FC16 may require voltage level adjustments and clock speed verification. Ensure any replacement maintains the same 8-lead MSOP package dimensions for board compatibility.
