24FC515-I/SM

Memory IC Overview

The Microchip Technology 24FC515-I/SM is a 512Kbit (64K x 8) serial EEPROM utilizing 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 features a 64-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead SOIJ package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz operation at voltages above 2.5V
• Includes a 64-byte page write buffer for efficient data transfer
• Provides hardware write protection through the dedicated WP pin

Memory IC Applications

• Personal communications devices
• Data acquisition systems
• Industrial control applications requiring non-volatile storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage supply meets the minimum 2.5V requirement for 1 MHz operation. Ensure the A2 pin is hard-wired to VCC as it is non-configurable. Check RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 512Kbit capacity with high-speed 1 MHz I2C communication is required. It is suitable for designs needing hardware write protection and robust noise immunity via Schmitt triggers. Compare against 24LC515 or 24AA515 variants if lower speed or different voltage ranges are acceptable for the application.

Memory IC Part Context

This part belongs to the 24XX515 family of CMOS Serial EEPROMs from Microchip Technology. It shares functional similarities with the 24LC515 and 24AA515 but offers higher clock speeds at standard operating voltages. The family supports cascading up to four devices on a single bus for expanded memory addressing.

Memory IC Replacement Considerations

Public confirmed substitutes include 24LC515-I/SM and 24AA515-I/SM. Note that these alternatives operate at a maximum clock frequency of 400 kHz.
