24LC32A-E/MS

Memory IC Overview

The Microchip Technology 24LC32A-E/MS 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 protocols, supporting clock frequencies up to 400 kHz for VCC between 2.5V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and utilizes an 8-lead MSOP surface-mount package.

Memory IC Feature Summary

• Supports page write operations with a 32-byte buffer to enhance bus throughput efficiency.
• Includes hardware write protection via the WP pin to inhibit array modifications when tied high.
• Provides Schmitt trigger inputs on SDA and SCL pins to suppress noise spikes and eliminate ground bounce.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices needing low-power memory
• Industrial control applications operating in extended temperature environments

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm RoHS compliance status and ensure the supply voltage range matches the application requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component for designs requiring I2C compatibility and robust data retention. Ensure the system voltage remains above 2.5V to maintain 400 kHz clock speeds. Consider the 32-byte page write capability for optimizing write performance in memory-intensive applications.

Memory IC Part Context

This part belongs to the 24XX32A family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA32A, which supports lower voltages down to 1.7V. The 24LC32A series is specifically designed for standard voltage operations starting at 2.5V.

Memory IC Replacement Considerations

The 24AA32A-E/MS serves as a functional substitute within the same package, offering operation down to 1.7V instead of 2.5V. Verify voltage compatibility and temperature ratings when substituting.
