24LC32AT-E/MC

Memory IC Overview

The Microchip Technology 24LC32AT-E/MC is a 32-Kbit Electrically Erasable PROM organized as 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 I²C compatible serial interface, Schmitt trigger inputs for noise suppression, and hardware write protection. It supports page writes up to 32 bytes with a maximum write cycle time of 5 ms. The component is rated for an industrial temperature range of -40°C to +125°C and is housed in an 8-lead DFN package.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol
• Includes hardware write protection via dedicated pin
• Features internal address pointer for sequential operations
• Provides acknowledge polling capability during write cycles

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices
• Industrial control applications
• Low-power embedded systems

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates extended temperature rating (-40°C to +125°C) and 'MC' denotes the 8-lead DFN package. Confirm RoHS compliance status matches project requirements. Ensure the ordering suffix does not alter functional specifications unless explicitly documented by the manufacturer. Cross-reference datasheet revision dates for accuracy.

Memory IC Selection Notes

Select this component when operating voltages are between 2.5V and 5.5V. Choose the 24LC32A series over 24AA32A if the minimum supply voltage requirement exceeds 1.7V. Consider the 8-lead DFN package for surface mount applications requiring compact footprints. Verify bus capacitance limits for high-speed 400 kHz operation.

Memory IC Part Context

This part belongs to the 24XX32A family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA32A but differs in minimum operating voltage. The device is designed for advanced low-power applications and offers factory programming options. It utilizes standard I²C addressing protocols for system integration.

Memory IC Replacement Considerations

The 24AA32AT-I/MC serves as a functional substitute within the same package type, provided the system voltage remains above 2.5V. Verify that the replacement part's temperature rating meets application needs. Ensure pin compatibility and electrical characteristics align before substitution.
