24FC04H-I/SN

Memory IC Overview

The Microchip Technology 24FC04H-I/SN is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 1 MHz across the full supply voltage range of 1.7V to 5.5V. The device includes hardware write-protect functionality for half the array and utilizes low-power CMOS technology.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation within the specified voltage range
• Includes hardware write-protect capability for the upper half of the memory array
• Features Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial environments
• Configuration storage in consumer electronics
• Parameter retention in automotive systems

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 the specific revision level of the datasheet DS20002119C matches the component batch requirements for your design integration.

Memory IC Selection Notes

Select this part when 1 MHz bus speed is required at voltages below 2.5V, distinguishing it from the 24LC04BH variant which is limited to 400 kHz at lower voltages. Ensure the application requires the specific half-array write protection feature provided by the WP pin configuration.

Memory IC Part Context

This component belongs to the 24XX04H family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA04H and 24LC04BH but offers distinct performance characteristics regarding maximum clock frequency and minimum operating voltage thresholds.

Memory IC Replacement Considerations

The 24LC04H-I/SN serves as a functional substitute if the system operates exclusively above 2.5V and does not require the 1 MHz clock speed capability.
