24FC04-I/SN

Memory IC Overview

The Microchip Technology 24FC04-I/SN is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C serial interface. It supports clock frequencies up to 1 MHz and operates on a single supply voltage ranging from 1.7V to 5.5V. The device includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-pin SOIC package and rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer with a maximum clock frequency of 1 MHz
• Enables hardware-based protection against unauthorized writes through the Write-Protect pin
• Incorporates Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce
• Features low-power CMOS technology with standby current as low as 1 µA

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation
• Device identification and calibration data retention

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'SN' indicates the 8-Lead SOIC package. Confirm compatibility with the host system's I²C bus voltage levels, noting operation down to 1.7V. Ensure the design accounts for the 16-byte page write boundary limitations to prevent data rollover during bulk writes.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is required alongside high-speed 1 MHz communication capabilities. It is suitable for applications needing wide voltage flexibility from 1.7V to 5.5V. Choose this part over variants like the 24LC04B if higher clock speeds are necessary, or over the 24AA04 if operation below 2.5V is required.

Memory IC Part Context

This device belongs to the 24XX04 family of serial EEPROMs, which shares architectural similarities with the 24AA04 and 24LC04B. While all three offer 4-Kbit capacity and I²C interfaces, the 24FC04 is distinguished by its support for 1 MHz clock speeds and operation at voltages as low as 1.7V, making it distinct within the series.

Memory IC Replacement Considerations

Direct functional substitutes within the same package include the 24FC04T-I/SN (Tape & Reel) and 24FC04-E/SN (Extended Temperature). For lower speed requirements, the 24LC04B-I/SN may be used if the system voltage remains above 2.5V.
