24AA16-I/P

Memory IC Overview

The Microchip Technology 24AA16-I/P 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. The device features a two-wire serial interface compatible with I2C protocols, supporting industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum active read current of 1 mA and standby current of 1 μA. It utilizes an 8-lead PDIP package for through-hole mounting.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial interface compatible with I2C protocols
• 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 bus
• Provides output slope control designed to eliminate ground bounce during operation

Memory IC Applications

• Data logging in industrial environments requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Calibration data retention for sensor modules
• Device identification and tracking information storage

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically PDIP for this part number. Confirm the temperature grade corresponds to the Industrial range (-40°C to +85°C). Ensure the voltage supply requirements align with the specified 1.7V to 5.5V operational window. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Memory IC Selection Notes

Select this component when a low-voltage EEPROM with I2C compatibility is required for through-hole applications. The 16-Kbit capacity suits small data storage needs such as configuration settings. Consider the 400 kHz speed limit and page write buffer size for system timing constraints. Verify that the operating voltage range covers the minimum system supply level of 1.7V.

Memory IC Part Context

This device belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24LC16B and 24FC16 variants, differing primarily in voltage thresholds and clock speeds. The 24AA16 variant is distinguished by its ability to operate down to 1.7V, unlike the 2.5V minimum of the LC series.

Memory IC Replacement Considerations

Direct substitutes within the same family include other package variations of the 24AA16. Cross-family replacements like the 24LC16B require verification of the minimum supply voltage compatibility.
