24AA64T-E/MNYVAO

Memory IC Overview

The Microchip Technology 24AA64T-E/MNYVAO is a 64-Kbit Electrically Erasable PROM (EEPROM) organized as an 8K x 8-bit memory block. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz for operation between 2.5V and 5.5V, and 100 kHz below 2.5V. The device operates within a supply voltage range of 1.7V to 5.5V and supports industrial temperature grades (-40°C to +85°C). Key electrical characteristics include a maximum active current of 3 mA, standby current of 1 µA, and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports page write operations with a 32-byte buffer to enhance bus throughput efficiency.
• Includes hardware write-protect functionality via the WP pin to secure array data against unauthorized modifications.
• Features Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce effects.

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in automotive electronic modules

Memory IC Procurement Notes

Verify that the ordering suffix 'VAO' corresponds to specific packaging or compliance requirements defined by the manufacturer. Confirm the package type matches the design footprint, as this part utilizes surface-mount technology. Ensure the extended temperature grade aligns with the operational environment specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when low-power consumption and high endurance are critical for long-term reliability. The 24AA64 series offers flexibility through multiple package options and address pin configurations. Consider the 24FC64 variant if higher clock speeds are required, or the 24LC64 if the minimum operating voltage must be strictly 2.5V or higher.

Memory IC Part Context

This EEPROM belongs to the 24XX64 family, which includes the 24AA64, 24FC64, and 24LC64 variants. These devices share a common architecture but differ in speed capabilities and voltage thresholds. The 24AA64 specifically targets general-purpose applications requiring robust performance across wide voltage ranges without the high-speed demands of the FC version.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA64T-I/MNY for industrial temperature ranges. Cross-family replacements like the 24LC64T-E/MNY are viable if the application voltage does not drop below 2.5V. Verify pin compatibility and software protocol adherence when integrating alternative packages from the 24XX64 series.
