24AA16T-I/SN

Memory IC Overview

The Microchip Technology 24AA16T-I/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz at voltages above 2.5V, or 100 kHz below 2.5V. The device utilizes a two-wire serial interface compatible with I2C protocols. It features a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component is available in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication with I2C compatibility
• Includes a 16-byte page write buffer for efficient data transfer
• Provides hardware write protection through the dedicated WP pin
• Features Schmitt trigger inputs to suppress bus noise

Memory IC Applications

• Data storage in low-voltage embedded systems
• Configuration parameter retention in industrial controllers
• Device identification and calibration data logging

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm the 'T' suffix matches the required tape-and-reel packaging format rather than tube. Ensure the system voltage requirements align with the 1.7V minimum operating specification for the 24AA16 series.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM capacity is required with a wide 1.7V to 5.5V supply range. It is suitable for applications needing hardware write protection and high ESD tolerance. Compare against the 24LC16B if a higher minimum voltage of 2.5V is acceptable, or the 24FC16 if a 1 MHz clock speed is necessary.

Memory IC Part Context

This part belongs to the Microchip 24XX16 family of 16-Kbit serial EEPROMs. The family includes variants like the 24LC16B and 24FC16, which share similar architectures but differ in minimum operating voltage and maximum clock frequency specifications. The 24AA16 variant specifically supports operation down to 1.7V.

Memory IC Replacement Considerations

Direct functional substitutes within the same datasheet include the 24LC16B and 24FC16, provided their specific voltage and speed constraints meet the design requirements.
