24LC32AT-E/SN

Memory IC Overview

The Microchip Technology 24LC32AT-E/SN is a 32-Kbit Electrically Erasable PROM (EEPROM) organized as a single block of 4K x 8-bit memory. It operates on a single supply with a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. The device features a two-wire serial interface compatible with I²C™, Schmitt trigger inputs for noise suppression, and hardware write-protect capabilities. It is qualified under AEC-Q100 standards and operates within an extended temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports up to eight devices on the same bus using functional address lines
• Includes a 32-byte page write buffer for efficient data storage
• Provides hardware write protection via the WP pin

Memory IC Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Data acquisition systems needing non-volatile storage
• Personal communication devices utilizing low-power operation

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the E suffix corresponds to the extended temperature range specifications. Ensure compatibility with the host system's I²C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when an I²C-compatible EEPROM with automotive qualification is required. The 24LC32A series is suitable for applications demanding high endurance and long data retention. Consider the MSOP or SOIC packages based on available PCB space and mounting requirements.

Memory IC Part Context

This part belongs to the 24XX32A family of 32-Kbit serial EEPROMs from Microchip Technology. The family includes variants like the 24AA32A, which supports lower voltages down to 1.7V. The 24LC32A variant specifically targets applications requiring operation between 2.5V and 5.5V.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC32A-E/MS and 24LC32A-E/SN. Verify package dimensions and electrical characteristics match the original design requirements.
