24FC515-I/P

Memory IC Overview

The Microchip Technology 24FC515-I/P is a 64K x 8 (512 Kbit) Serial Electrically Erasable PROM featuring an I²C-compatible interface. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 1 MHz. The device utilizes low-power CMOS technology, offering typical active current of 500 µA and standby current of 100 nA. It includes a 64-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. Data retention exceeds 200 years with over one million erase/write cycles endurance.

Memory IC Feature Summary

• Supports high-speed serial data transfer up to 1 MHz using a standard two-wire I²C compatible protocol.
• Features a 64-byte page write buffer that allows efficient sequential data storage operations.
• Includes hardware write protection capability through the dedicated WP pin to secure memory arrays.
• Provides robust noise immunity via Schmitt trigger inputs on all communication pins.

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple configurations. Confirm the temperature grade corresponds to the intended operating environment. Ensure compatibility with system voltage levels before integration. Check for any recent product change notifications regarding packaging or assembly updates.

Memory IC Selection Notes

Select this component when a high-speed I²C EEPROM is required for industrial environments. The 24FC515 offers faster clock speeds compared to standard variants. Consider the PDIP-8 package for through-hole mounting requirements. Evaluate system power constraints against the specified active and standby current values.

Memory IC Part Context

This device belongs to the 24XX515 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA515 and 24LC515 but distinguishes itself through higher clock frequency capabilities. The family provides scalable memory solutions for various embedded applications requiring persistent data storage.

Memory IC Replacement Considerations

Direct substitutes include the 24LC515 and 24AA515, though they operate at lower maximum clock frequencies. Verify voltage range compatibility, as the 24AA515 supports operation down to 1.7V while the 24FC515 requires a minimum of 2.5V.
