24LC64T-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC64T-E/SN16KVAO is a 64-Kbit Electrically Erasable PROM (EEPROM) organized as an 8K x 8-bit memory block. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz at supply voltages between 2.5V and 5.5V. The device supports page write operations with a 32-byte buffer and includes hardware write protection via the WP pin. It operates within an extended temperature range of -40°C to +125°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports bidirectional, two-wire serial data transmission protocol compatible with standard I2C bus requirements.
• Includes a 32-byte page write buffer to facilitate efficient multi-byte data storage operations.
• Provides hardware-based write protection capability through the dedicated Write-Protect input pin.

Memory IC Applications

• Data logging applications requiring non-volatile storage for sensor readings or event timestamps
• Configuration parameter storage in embedded systems where power-down retention is critical
• Device identification and calibration data storage in industrial control modules

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status and automotive qualification if applicable to your design. Ensure the voltage supply range aligns with the 2.5V minimum requirement for the LC series variant. Check for any recent Product Change Notifications regarding packaging or assembly site updates.

Memory IC Selection Notes

Select this component when an I2C interface is preferred over SPI for memory expansion. The 64-Kbit capacity suits applications needing moderate data retention without complex addressing schemes. Consider the 32-byte page buffer size for write efficiency. Ensure the system voltage remains above 2.5V to maintain the specified 400 kHz clock speed. Verify that the physical footprint accommodates the 8-lead SOIC package dimensions.

Memory IC Part Context

This part belongs to the 24LC64 family of serial EEPROMs from Microchip Technology. The 'E' designation indicates an extended temperature range suitable for harsh environments. The 'SN' suffix specifies the 8-lead Small Outline Integrated Circuit package. The 'T' indicates tape and reel packaging for automated assembly processes.

Memory IC Replacement Considerations

Direct replacements include other 24LC64 variants with different packages such as 24LC64T-I/SN for industrial temperature ranges. Cross-reference with 24AA64 or 24FC64 only if voltage levels or clock speeds differ significantly from the 2.5V-5.5V and 400kHz specifications.
