24AA64T-I/MNY

Memory IC Overview

The Microchip Technology 24AA64T-I/MNY is a 64-Kbit Electrically Erasable PROM (EEPROM) organized as an 8K x 8-bit memory block. 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 low-power CMOS technology, drawing a maximum active current of 3 mA and a standby current of 1 µA. It utilizes a two-wire serial interface compatible with I2C protocols.

Memory IC Feature Summary

• Supports bidirectional data transfer via a two-wire serial interface compatible with I2C protocols
• Includes a 32-byte page write buffer for efficient sequential data storage operations
• Features hardware write protection controlled by the WP pin to prevent unauthorized modifications
• Provides Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce

Memory IC Applications

• Industrial systems requiring non-volatile data retention in harsh environments
• Embedded controllers needing configuration parameter storage
• Low-voltage portable devices utilizing battery power sources
• Automotive qualified applications meeting AEC-Q100 standards

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the presence of tape-and-reel packaging indicated by the 'T' designation. Ensure compatibility with the target system's voltage levels and I2C bus specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 64-Kbit capacity is sufficient for application requirements. Choose this part over higher density options if lower cost or smaller physical footprint is prioritized. Consider the industrial temperature range suitability for the intended operating environment.

Memory IC Part Context

This device belongs to the 24XX64 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24FC64 and 24LC64 variants, differing primarily in supported voltage ranges and maximum clock frequencies. The MNY suffix specifically denotes the 8-lead TDFN package configuration.

Memory IC Replacement Considerations

Direct substitutes within the same family include other 24AA64 variants with different package suffixes such as 24AA64-I/ST or 24AA64-I/SN. Cross-family replacements like 24LC64 require verification of minimum supply voltage compatibility.
