24LC512-E/SN

Memory IC Overview

The Microchip Technology 24LC512-E/SN is a 512 Kbit (64K x 8) serial electrically erasable PROM featuring an I²C compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead SOIC package and functions across an extended temperature range from -40°C to +125°C. Key electrical characteristics include a maximum access time of 900 ns, a page write buffer of 128 bytes, and a maximum write cycle time of 5 ms.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using functional address lines A0, A1, and A2.
• Includes hardware write protection via the WP pin to inhibit array writes when tied to VCC.
• Features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Provides random and sequential read capabilities up to the full memory boundary.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices needing parameter retention
• Embedded applications requiring reliable configuration data preservation

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature grade (-40°C to +125°C) and 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status as specified in the manufacturer's documentation. Ensure the application design accommodates the 2.5V minimum supply voltage requirement specific to the 24LC512 series.

Memory IC Selection Notes

Select this component when operation below 2.5V is not required, as the 24AA512 variant supports lower voltages. Choose the 24LC512-E/SN specifically for environments demanding extended temperature stability. Consider the 128-byte page write buffer size for optimizing write throughput in software drivers.

Memory IC Part Context

This part belongs to the 24XX512 family of 512 Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA512 and 24FC512, which differ primarily in operating voltage ranges and maximum clock speeds. The 24LC512 is optimized for standard 3.3V and 5V logic systems.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC512-I/SN for industrial temperature grades and 24LC512T-E/SN for tape and reel packaging options within the same package type.
