24AA16T-I/MC16KVAO

Memory IC Overview

The Microchip Technology 24AA16T-I/MC16KVAO 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 voltages above 2.5V, and 100 kHz below 2.5V. The device features low-power CMOS technology with a maximum active read current of 1 mA and standby current of 1 μA in industrial temperature ranges (-40°C to +85°C). It supports I²C compatible two-wire serial interfaces, includes hardware write-protect functionality via the WP pin, and offers over one million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol compatible with standard I²C bus specifications.
• Includes a 16-byte page write buffer to facilitate efficient sequential data storage operations.
• Provides hardware-based write protection for the entire memory array through the dedicated WP pin.
• Features Schmitt trigger inputs and noise suppression circuits to ensure reliable operation on noisy buses.

Memory IC Applications

• Data acquisition systems requiring non-volatile parameter storage
• Personal communications devices needing configuration memory
• Industrial control units storing calibration constants

Memory IC Procurement Notes

Verify that the specific suffix '16KVAO' aligns with the manufacturer's current packaging and marking conventions for the DFN-8 package. Confirm that the Industrial temperature grade meets the operational requirements of the target environment. Ensure compatibility with the system's I²C pull-up resistor values given the 1.7V to 5.5V operating range.

Memory IC Selection Notes

Select this component when a compact surface-mount EEPROM is required for low-voltage applications. The 1.7V minimum operating voltage makes it suitable for battery-powered designs. The 400 kHz clock speed provides adequate throughput for most control applications. Consider the 16-byte page size when designing write algorithms to optimize bus efficiency.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which also includes the 24LC16B and 24FC16 variants. While sharing the same memory architecture and interface, the 24AA16 is distinguished by its lower 1.7V minimum operating voltage compared to the 24LC16B's 2.5V requirement. It shares physical package options with other family members but differs in electrical characteristics and temperature grades.
