24AA16-E/MS

Memory IC Overview

The Microchip Technology 24AA16-E/MS is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire I2C compatible serial interface and operates on a single supply voltage ranging from 1.7V to 5.5V. The device supports page write operations with a maximum buffer size of 16 bytes and includes hardware write-protect functionality via the WP pin. It offers Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports bidirectional data transmission over a two-wire serial bus with I2C compatibility.
• Includes hardware write protection controlled by the WP pin to inhibit write operations when tied high.
• Features Schmitt trigger inputs and filter circuits to suppress noise spikes on the SCL and SDA lines.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade (E for Extended) and package type (MSOP). Confirm RoHS compliance status and ensure the specific revision aligns with current manufacturing standards. Cross-reference the full part number against official distributor catalogs to validate availability and authenticity before finalizing procurement orders.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with low standby current and operation down to 1.7V. Ensure the system design accommodates the 400 kHz maximum clock frequency at voltages above 2.5V, or limits speed to 100 kHz below that threshold. Verify that the MSOP package dimensions fit the available PCB space and thermal requirements.

Memory IC Part Context

This device belongs to the 24XX16 family of 16-Kbit I2C Serial EEPROMs, which also includes the 24LC16B and 24FC16 variants. While sharing similar memory organization and interface protocols, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24AA16 specifically supports operation down to 1.7V with a 400 kHz interface speed.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA16T-E/ST and 24AA16H-I/MS, provided the package and temperature grades match the application requirements. Other variants like the 24LC16B or 24FC16 may require voltage level adjustments due to different minimum operating voltage specifications.
