24LC32A-E/SM

Memory IC Overview

The Microchip Technology 24LC32A-E/SM is a 32-Kbit Electrically Erasable PROM (EEPROM) organized as a single block of 4K x 8-bit memory. It features a two-wire serial interface compatible with I2C™ standards, 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, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports page write operations with a 32-byte page write buffer for efficient data handling.
• Includes hardware write-protect functionality via the WP pin to secure the entire memory array.
• Features Schmitt trigger inputs on SDA and SCL pins to provide improved noise spike suppression.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Extended temperature range (-40°C to +125°C). Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation matching the manufacturer's part number format. Check for any recent Product Change Notifications affecting assembly or labeling.

Memory IC Selection Notes

Select this component when an I2C-compatible EEPROM with extended industrial temperature ratings is required. Ensure the system voltage remains within the 2.5V to 5.5V operating range. Consider the 32-byte page buffer size for write optimization and verify that the application can accommodate the physical dimensions of the 8-lead MSOP package.

Memory IC Part Context

This part belongs to the 24XX32A family of 32-Kbit Serial EEPROMs manufactured by Microchip Technology. The 'E' designation indicates an extended temperature range capability compared to the standard Industrial grade variants. The 'SM' suffix identifies the specific surface-mount packaging configuration used for this device variant.

Memory IC Replacement Considerations

The 24AA32A series serves as a functional substitute within the same family, offering similar memory organization and interface protocols. Verify voltage compatibility, as the 24AA32A supports lower voltage operation down to 1.7V compared to the 2.5V minimum of the 24LC32A.
