24LC32A/SN

Memory IC Overview

The Microchip Technology 24LC32A/SN is a 32-Kbit Electrically Erasable PROM organized as a single block of 4K x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with 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 supports page writes of up to 32 bytes and offers data retention exceeding 200 years with over one million erase/write cycles endurance.

Memory IC Feature Summary

• Two-wire serial interface compatible with I2C protocol
• Hardware write-protect functionality via WP pin
• Schmitt trigger inputs for improved noise suppression
• Self-timed erase/write cycle with page write buffer

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Low-power embedded applications

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package and Industrial temperature range (-40°C to +85°C) as defined in the manufacturer's selection table. Confirm that the extended temperature variant requires an 'E' designation if higher thermal limits are necessary for the target environment.

Memory IC Selection Notes

Select this component when a 32-Kbit non-volatile memory solution is required with I2C connectivity. Ensure the system voltage remains within the 2.5V to 5.5V operating range. Consider the 32-byte page write buffer for efficient data handling and utilize the hardware write-protect pin if physical protection against accidental writes is required.

Memory IC Part Context

This part belongs to the 24AA32A/24LC32A family of 32-Kbit Serial EEPROMs. The 'LC' designation indicates operation down to 2.5V, distinguishing it from the 'AA' variant which supports lower voltages. The 'SN' suffix identifies the surface-mount SOIC-8 package type, suitable for automated assembly processes.

Memory IC Replacement Considerations

The 24AA32A/SN serves as a functional substitute with identical pinout and memory organization, differing primarily in its ability to operate at voltages below 2.5V.
