24FC04H-E/SN

Memory IC Overview

The Microchip Technology 24FC04H-E/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 operates within an extended temperature range of -40°C to +125°C and utilizes an 8-lead SOIC package.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for efficient data transfer
• Includes hardware write protection for half of the memory array
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides page write capability with a 16-byte buffer

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating at low voltages
• Parameter retention in automotive electronic modules

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) and 'SN' indicates the 8-lead SOIC package. Confirm the specific datasheet revision matches the required electrical characteristics for your design constraints.

Memory IC Selection Notes

Select this component when high-speed 1 MHz communication is necessary alongside low-voltage operation down to 1.7V. Ensure the application requires the specific half-array write protection feature provided by the WP pin configuration rather than full-array protection.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit EEPROMs. It shares architectural similarities with the 24AA04H and 24LC04BH but offers superior clock speed compatibility compared to the 400 kHz variants found in other family members.

Memory IC Replacement Considerations

Direct substitutes include the 24FC04H-I/SN for Industrial temperature range applications or the 24LC04BH-E/SN if the system voltage remains above 2.5V and lower clock speeds are acceptable.
