24FC515T-I/SM

Memory IC Overview

The Microchip Technology 24FC515T-I/SM is a 512Kbit (64K x 8) Serial Electrically Erasable PROM featuring an I²C-compatible interface. It supports a maximum clock frequency of 1 MHz and operates within a supply voltage range of 2.5V to 5.5V. The device utilizes an 8-lead SOIJ package with surface mount installation. Key electrical parameters include a typical active current of 500 µA, standby current of 100 nA, and access time of 400 ns. It offers over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports high-speed serial communication via a 2-wire I²C compatible bus protocol.
• Includes a 64-byte page write buffer for efficient sequential data programming.
• Features hardware write protection controlled by the WP pin to prevent accidental data modification.
• Provides robust noise immunity through Schmitt trigger inputs on all communication pins.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to the specific reel packaging configuration required for automated assembly processes. Confirm the 'I' temperature grade matches the operational environmental specifications of the target application. Ensure compatibility with the 2.5V minimum supply voltage requirement inherent to the 24FC series architecture.

Memory IC Selection Notes

Select this component when a 1 MHz I²C clock speed is necessary, as other variants in the family may be limited to 400 kHz. The 24FC515 requires a minimum supply voltage of 2.5V, distinguishing it from lower-voltage alternatives. The SOIJ package is suitable for space-constrained surface mount designs requiring standard 8-pin footprint dimensions.

Memory IC Part Context

This part belongs to the 24AA515/24LC515/24FC515 family of 512K I²C CMOS Serial EEPROMs. While sharing core memory architecture, the 24FC variant is specifically optimized for higher clock frequencies up to 1 MHz compared to the 400 kHz limit of the 24LC series. The 'T' suffix indicates tape and reel packaging, facilitating high-volume manufacturing integration.

Memory IC Replacement Considerations

Direct functional substitutes within the same datasheet include the 24FC515 in PDIP or SOIC packages. For applications requiring lower voltage operation down to 1.7V, the 24AA515 is an alternative, though it is limited to a 400 kHz clock frequency.
