24LC515-I/SM

Memory IC Overview

The Microchip Technology 24LC515-I/SM is a 64K x 8 (512K bit) Serial Electrically Erasable PROM. It features an I2C compatible interface with a maximum clock frequency of 400 kHz for the 2.5V to 5.5V supply range. The device operates within a temperature range of -40°C to +85°C and utilizes low-power CMOS technology.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial bus protocol
• Includes hardware write protection controlled by the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides up to one million erase/write cycle endurance

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Industrial control applications

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C). Confirm the package designation 'SM' matches the required 8-lead SOIJ footprint. Ensure the voltage requirements align with the specified 2.5V to 5.5V operating range for this specific part variant.

Memory IC Selection Notes

Select this component when a 512Kbit EEPROM capacity is required with standard I2C compatibility. The industrial temperature rating makes it suitable for general-purpose embedded memory storage where moderate speed and low power consumption are prioritized over high-frequency operation.

Memory IC Part Context

This device belongs to the 24XX515 family, which includes variants like the 24AA515 and 24FC515. While sharing similar architecture, the 24LC515 specifically supports a 2.5V minimum supply voltage and 400 kHz clock speed, distinguishing it from lower-voltage or higher-speed counterparts in the same series.

Memory IC Replacement Considerations

Direct substitutes include other 24LC515 variants with different packages such as 24LC515-I/P or 24LC515-I/SN. Cross-family replacements like the 24AA515 require verification of voltage compatibility.
