24LC32AFT-E/MS

Memory IC Overview

The Microchip Technology 24LC32AFT-E/MS 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 clock frequencies up to 400 kHz. The device operates on a single supply voltage ranging from 2.5V to 5.5V and utilizes low-power CMOS technology. It includes hardware write-protect capabilities for one-quarter of the array and supports page writes of up to 32 bytes.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial bus protocol
• Includes Schmitt trigger inputs for 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 temperature grade (-40°C to +125°C) and the MSOP package type. Confirm compliance with RoHS standards and ensure the selected variant matches the required voltage range of 2.5V to 5.5V for proper system integration.

Memory IC Selection Notes

Select this component when an automotive-grade EEPROM is required for environments operating up to 125°C. Ensure the design accommodates the 2.5V minimum supply voltage constraint, which differs from industrial variants. Verify that the 8-pin MSOP footprint aligns with the PCB layout requirements.

Memory IC Part Context

This part belongs to the 24LC32AF family of 32 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA32AF but is distinguished by its specific voltage operating range and temperature rating. The 'E' suffix denotes the extended automotive temperature range.
