24FC04T-I/SN

Memory IC Overview

The Microchip Technology 24FC04T-I/SN is a 4-Kbit (512 x 8) serial EEPROM utilizing an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device features a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It supports industrial temperature operation from -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication
• Includes a 16-byte page write buffer for efficient data transfer
• Features hardware write protection through the WP pin
• Provides ESD protection exceeding 4,000V

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

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-SOIC package. Confirm the specific datasheet revision matches the required electrical characteristics. Ensure compatibility with the host system's I²C bus voltage levels and pull-up resistor requirements for reliable signal integrity.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient and high-speed 1 MHz I²C access is required. It is suitable for applications needing low standby current and robust noise immunity via Schmitt triggers. Compare against the 24LC04B if only 400 kHz speed is needed or the 24AA04 if lower minimum voltage constraints apply.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs, which includes variants like the 24AA04 and 24LC04B. These devices share similar architectural features but differ in operating voltage ranges and maximum clock frequencies. The 24FC04 variant specifically enables full-speed operation down to 1.7V.

Memory IC Replacement Considerations

The 24LC04BT-I/SN offers identical packaging and pinout but is limited to 400 kHz operation. The 24AA04T-I/SN provides similar functionality but may have different timing specifications at voltages below 2.5V.
