24AA16T-E/MNY

Memory IC Overview

The Microchip Technology 24AA16T-E/MNY 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 I²C compatible two-wire serial interfaces at clock frequencies up to 400 kHz. The device features low-power CMOS technology with maximum standby current of 1 μA and read current of 1 mA. It includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control. The Extended temperature grade (E) supports operation from -40°C to +125°C.

Memory IC Feature Summary

• Supports page write operations with a 16-byte buffer for efficient data transfer
• Includes hardware write-protect capability via the WP pin to secure memory arrays
• Features Schmitt trigger inputs and filter circuits for enhanced noise immunity on noisy buses

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating at low voltages
• Parameter retention in battery-powered devices due to ultra-low standby current

Memory IC Procurement Notes

Verify that the ordering suffix 'MNY' corresponds specifically to the TDFN package type required for your PCB layout. Confirm the 'E' suffix indicates the Extended temperature range (-40°C to +125°C), which differs from the Industrial grade. Ensure compatibility with your system's I²C bus voltage levels, as the device supports operation down to 1.7V.

Memory IC Selection Notes

Select this component when an I²C EEPROM with extended temperature capability is needed. The 16-Kbit capacity suits applications requiring moderate non-volatile storage. Verify that the TDFN package fits your assembly constraints. Consider the 400 kHz speed limit if higher throughput is required, or check if the 24FC16 variant is suitable for 1 MHz operation.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24LC16B and 24FC16 but differs in voltage ranges and clock speeds. The 24AA16 series is designed for low-voltage applications, while the 24FC16 offers higher speed capabilities. All variants utilize the same basic I²C protocol and pinout structure.

Memory IC Replacement Considerations

Direct substitutes include other 24AA16 variants with different package options such as SOIC or TSSOP. Cross-family replacements like the 24LC16B are possible but require verification of minimum voltage requirements, as it typically starts at 2.5V. The 24FC16 offers faster performance but may have different electrical characteristics.
