24LC256T-E/MNY

Memory IC Overview

The Microchip Technology 24LC256T-E/MNY is a 32K x 8 (256-Kbit) Serial Electrically Erasable PROM (EEPROM). It operates with a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a Two-Wire Serial Interface compatible with I2C. The device features a 64-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is housed in an 8-Lead TDFN package and is rated for an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial data transmission protocol

• Features a 64-byte page write buffer for efficient data storage
• Provides high ESD protection exceeding 4000V on all pins

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Advanced low-power applications requiring non-volatile memory

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the design accounts for the moisture sensitivity level indicated in the datasheet prior to PCB assembly.

Memory IC Selection Notes

Select this component when a 256-Kbit capacity is required within an 8-lead TDFN footprint. The Extended temperature rating (-40°C to +125°C) makes it suitable for harsh environments. Ensure the system voltage remains above 2.5V to maintain the specified 400 kHz clock speed compatibility.

Memory IC Part Context

This part belongs to the 24XX256 family, which includes the 24AA256 and 24FC256 variants. While sharing the same memory architecture and interface, the 24LC256 is distinguished by its minimum operating voltage of 2.5V, whereas other family members support lower voltages or higher clock speeds depending on the specific suffix.

Memory IC Replacement Considerations

Direct substitutes include other packages within the same series such as 24LC256T-E/ST or 24LC256T-E/SM, provided the pinout and electrical characteristics remain identical. Verify that any alternative package maintains the same extended temperature rating and voltage specifications.
