24AA16-I/MC16KVAO

Memory IC Overview

The Microchip Technology 24AA16-I/MC16KVAO 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 an I2C compatible two-wire serial interface and features a 16-byte page write buffer. It includes hardware write protection via the WP pin and offers data retention exceeding 200 years with over one million erase/write cycles endurance.

Memory IC Feature Summary

• Supports low-voltage operation down to 1.7V with minimal active and standby current consumption.
• Features a 16-byte page write buffer for efficient sequential data writing operations.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides hardware write protection on the entire memory array through the dedicated WP pin.

Memory IC Applications

• Industrial systems requiring non-volatile data storage in noisy environments
• Consumer electronics utilizing I2C bus communication protocols
• Embedded controllers needing reliable parameter storage with long data retention

Memory IC Procurement Notes

Verify that the ordering suffix matches the specific package type and temperature grade required for your design. Confirm whether the '16KVAO' suffix indicates factory programming or specific automotive qualification status by consulting the official Microchip datasheet. Ensure compatibility with your system's I2C pull-up resistor values and voltage levels before finalizing procurement.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is sufficient and low power consumption is critical. It is suitable for applications operating between 1.7V and 5.5V where standard I2C speeds are adequate. Consider the 8-lead DFN package for compact surface-mount designs. Verify that the industrial temperature range meets your environmental requirements.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which also includes the 24LC16B and 24FC16 variants. While sharing similar architecture, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24AA16 specifically supports operation down to 1.7V, distinguishing it from the 2.5V minimum 24LC16B.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA16T-E/ST for TSSOP packaging or other 24AA16 variants with different package codes such as 24AA16-I/P for PDIP. Cross-family replacements like the 24LC16B require verification of the higher minimum voltage requirement.
