24LC64-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC64-E/SN16KVAO is a 64-Kbit (8K x 8) serial EEPROM utilizing a two-wire I2C compatible interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features industrial temperature ratings from -40°C to +85°C, hardware write protection via the WP pin, and a 32-byte page write buffer. It offers high endurance exceeding one million erase/write cycles and data retention for over 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication with 100 kHz and 400 kHz clock compatibility
• Includes a 32-byte page write buffer for efficient data transfer operations
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Provides hardware write protection through the dedicated WP pin

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Automotive qualified applications using AEC-Q100 compliant variants
• Smart metering devices for utility usage logging

Memory IC Procurement Notes

Verify that the specific suffix 'SN16KVAO' corresponds to the standard SOIC-8 package and Extended Temperature grade as defined in the official datasheet. Confirm RoHS compliance status and ensure the ordering code matches the exact voltage and speed requirements for your design. Cross-reference the manufacturer's current product change notifications to validate component availability and lifecycle status before finalizing procurement.

Memory IC Selection Notes

Select this component when an I2C interface is required for low-pin-count memory expansion. Ensure the system voltage remains above 2.5V to meet the specified operating range for the LC series. Consider the 32-byte page buffer size when designing software drivers to optimize write throughput. Verify that the physical package dimensions fit the available PCB real estate constraints.

Memory IC Part Context

This part belongs to the 24XX64 family of serial EEPROMs, which includes the 24AA64 and 24FC64 variants. While sharing the same architecture and interface, the 24LC64 is distinguished by its minimum operating voltage of 2.5V compared to the 1.7V capability of the AA and FC versions. The SN suffix indicates an 8-lead Small Outline Integrated Circuit package suitable for surface mount assembly.

Memory IC Replacement Considerations

Direct functional substitutes include the 24LC64-I/SN for industrial temperature ranges or the 24LC64-E/MS for MSOP packaging. For higher speed requirements, the 24FC64 series offers 1 MHz operation but requires verification of voltage compatibility.
