24AA16T-E/OT16KVAO

Memory IC Overview

The Microchip Technology 24AA16T-E/OT is a 16-Kbit (2K x 8) serial electrically erasable PROM 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 a 5-lead SOT-23 package and offers extended temperature operation from -40°C to +125°C. Key electrical characteristics include a maximum active read current of 1 mA and standby current of 3 μA.

Memory IC Feature Summary

• Supports hardware write protection via the WP pin to inhibit memory writes when tied high
• Includes Schmitt trigger inputs and noise filtering for reliable data transmission on noisy buses
• Features a 16-byte page write buffer to optimize write throughput efficiency
• Provides output slope control mechanisms designed to eliminate ground bounce effects

Memory IC Applications

• Embedded systems requiring non-volatile data storage with limited I/O resources
• Low-power consumer electronics operating on battery supplies
• Industrial data acquisition systems needing wide temperature tolerance
• Automotive applications requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'OT' denotes the SOT-23-5 package. Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering code matches the required voltage and speed specifications for your design constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 5-lead surface-mount package is required for 16-Kbit EEPROM storage. It is suitable for designs needing operation down to 1.7V and compatibility with standard I²C buses. Consider the 16-byte page buffer for applications prioritizing write speed over byte-by-byte operations within the same block.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24LC16B and 24FC16, which share similar architectures but differ in voltage ranges and clock speeds. The 24AA16 specifically targets low-voltage applications with industrial and extended temperature grades.

Memory IC Replacement Considerations

Direct substitutes within the same package and specification include other 24AA16 variants with different suffixes for package type or temperature grade, such as 24AA16-I/OT or 24AA16-E/ST. Cross-family replacements like 24LC16B require verification of minimum voltage requirements.
