24LC32AFT-E/MNY

Memory IC Overview

The Microchip Technology 24LC32AFT-E/MNY is a 32 Kbit Electrically Erasable PROM organized as a single block of 4K x 8-bit memory. It features a 2-wire serial interface compatible with I2C™, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device operates on a single supply voltage ranging from 2.5V to 5.5V. It includes hardware write-protect capabilities for one-quarter of the array and utilizes a 32-byte page write buffer. The component is housed in an 8-lead TDFN package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a 2-wire serial bus protocol
• Includes Schmitt trigger inputs for enhanced noise suppression
• Features output slope control to eliminate ground bounce
• Provides hardware write protection for the upper quarter of the memory array

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Advanced low-power applications

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Automotive (E) temperature grade (-40°C to +125°C) and the TDFN package type. Confirm compliance with RoHS standards and ensure the selected variant matches the required voltage range specifications for your system design.

Memory IC Selection Notes

Select this component when automotive-grade reliability and extended temperature operation are required. Ensure the application supports the 2.5V minimum supply voltage constraint. Verify that the I2C bus timing requirements align with the specified AC characteristics for the chosen clock frequency.

Memory IC Part Context

This part belongs to the 24AA32AF/24LC32AF family of 32 Kbit EEPROMs. The 'LC' designation indicates a 2.5V minimum operating voltage, distinguishing it from the 'AA' series which supports lower voltages down to 1.7V. The 'E' suffix denotes the automotive temperature rating, while 'T' indicates tape and reel packaging.

Memory IC Replacement Considerations

Direct substitutes within the same package and electrical profile include other variants from the 24LC32AF family, such as 24LC32AF-E/MS or 24LC32AF-I/ST, provided the temperature grade and package dimensions match the design constraints.
