24AA256T-E/MNY

Memory IC Overview

The Microchip Technology 24AA256T-E/MNY is a 32K x 8 (256-Kbit) Serial Electrically Erasable PROM (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and supports I2C compatible two-wire serial interface with maximum clock frequencies of 100 kHz below 2.5V and 400 kHz at or above 2.5V. The device features a page write buffer for up to 64 bytes, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. It offers data retention exceeding 200 years and endurance of over one million erase/write cycles.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using configurable chip address inputs.
• Includes hardware write-protect functionality controlled by the WP pin to inhibit array writes.
• Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

• Personal communications systems requiring low-power non-volatile storage
• Data acquisition applications needing reliable parameter retention
• Embedded systems utilizing I2C bus architecture

Memory IC Procurement Notes

Verify that the ordering suffix 'MNY' corresponds specifically to the 8-WFDFN package type as indicated in official documentation. Confirm the temperature grade 'E' matches the required extended operating range specifications for your application environment before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an I2C-compatible EEPROM with a wide voltage range down to 1.7V is required. Ensure the design accommodates the specific 8-WFDFN footprint associated with the MNY suffix. Consider the 64-byte page write buffer size when designing software drivers to optimize write throughput and manage page boundary crossings correctly.

Memory IC Part Context

This part belongs to the 24AA256 family of 256-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different voltage ranges and temperature grades, such as the 24LC256 and 24FC256. The 24AA256 series is distinguished by its ability to operate down to 1.7V, making it suitable for advanced low-power applications compared to higher voltage counterparts.

Memory IC Replacement Considerations

Direct replacements within the same package and electrical characteristics include other 24AA256 variants with different suffixes such as 24AA256T-E/ST or 24AA256T-E/SN, provided the physical footprint matches the target PCB design. Verify temperature range compatibility when substituting industrial grade parts for extended grade ones.
