24FC08-I/SN

Memory IC Overview

The Microchip Technology 24FC08-I/SN is an 8-Kbit (1K x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead SOIC package. It features a two-wire I²C serial interface with a maximum clock frequency of 1 MHz when VCC is between 1.7V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum write cycle time of 5 ms, a typical access time of 450 ns, and low standby current of 1 µA.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication for efficient data transfer.
• Includes hardware write protection via the WP pin to prevent unauthorized memory modifications.
• Features Schmitt trigger inputs and noise filtering to ensure reliable operation on noisy buses.
• Provides a 16-byte page write buffer to optimize write throughput.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor interfaces

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C) and 'SN' specifies the 8-lead SOIC package. Confirm the voltage range supports your system's 1.7V to 5.5V requirement. Ensure the I²C bus speed matches the 1 MHz capability. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a 1 MHz I²C interface is required, distinguishing it from slower 400 kHz variants like the 24LC08B. The 1.7V minimum supply voltage allows compatibility with low-voltage logic systems where the 2.5V minimum of other family members would be insufficient. The SOIC package is suitable for standard surface-mount assembly processes.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA08 and 24LC08B but offers higher bus speeds. The family utilizes low-power CMOS technology and provides robust data retention and endurance specifications common across the series.

Memory IC Replacement Considerations

The 24FC08T-I/SN serves as a tape-and-reel replacement for the same functional device. Cross-family replacements like the 24LC08B are compatible electrically but operate at a lower 400 kHz maximum clock speed.
