24AA16T-E/OT

Memory IC Overview

The Microchip Technology 24AA16T-E/OT is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. 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 at VCC < 2.5V. The device supports I2C compatible two-wire serial interface, features a 16-byte page write buffer, and includes hardware write-protect functionality via the WP pin. It is rated for extended temperature operation from -40°C to +125°C and housed in an 8-lead OT package.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol compatible with I2C standards
• 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

• Data storage in battery-powered consumer electronics
• Configuration parameter retention in industrial control systems
• Calibration data storage in automotive electronic modules

Memory IC Procurement Notes

Verify that the ordering suffix 'OT' corresponds to the specific 8-lead package type required for your PCB layout. Confirm the 'E' designation indicates Extended temperature range (-40°C to +125°C) compatibility with your environmental specifications. Ensure the system design accommodates the 1.7V minimum operating voltage if utilizing low-voltage power supplies.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required within the 24AA16 family. The 'E' suffix denotes extended temperature performance suitable for harsh environments. The 'OT' suffix specifies the package style; verify footprint compatibility against other available packages like SOIC or TSSOP. This part is distinct from the 24LC16B which requires a higher minimum voltage.

Memory IC Part Context

This device belongs to the 24XX16 series of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24LC16B and 24FC16 but differs in voltage ranges and clock speeds. The 24AA16 variant specifically supports operation down to 1.7V, distinguishing it from parts requiring higher minimum voltages.

Memory IC Replacement Considerations

Direct functional substitutes within the same voltage and speed profile include the 24AA16T-I/OT for industrial temperature range. For higher speed requirements, the 24FC16 series may be considered if voltage levels align. Verify package pinout compatibility before substituting.
