24FC04T-E/MS

Memory IC Overview

The Microchip Technology 24FC04T-E/MS 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 and supports maximum clock frequencies up to 1 MHz across its full operating voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, ensuring active read currents remain at or below 1 mA while standby current does not exceed 3 µA in extended temperature conditions. Designed for robust operation, it accommodates an industrial temperature range from -40°C to +85°C and an extended range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed serial data transmission with clock frequencies reaching 1 MHz
• Includes a 16-byte page write buffer to optimize sequential data writing operations
• Provides hardware-based write protection via the dedicated WP pin
• Integrates Schmitt trigger inputs and output slope control for enhanced noise suppression

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control units needing reliable data retention under extreme temperatures
• Consumer electronics utilizing low-voltage power supplies
• Automotive modules requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the ordering suffix correctly identifies the MSOP package type and Extended temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability codes matching the specific production lot requirements for your manufacturing process.

Memory IC Selection Notes

Select this component when designs require 1 MHz bus speeds at voltages as low as 1.7V. The MSOP package offers a compact surface-mount solution suitable for space-constrained PCB layouts. Consider the hardware write-protect feature if system security against accidental overwrites is critical. Verify that the host controller supports the required I2C protocol timing specifications.

Memory IC Part Context

This part belongs to the 24XX04 family of 4-Kbit EEPROMs manufactured by Microchip Technology. While sharing core architectural similarities with the 24AA04 and 24LC04B variants, the 24FC04 specifically distinguishes itself through superior speed capabilities. It operates reliably at 1 MHz across the entire voltage spectrum, whereas other family members may be limited to lower frequencies at reduced voltages.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24FC04T-E/OT (SOT-23 package) and 24FC04-E/P (PDIP package). Cross-family replacements like the 24LC04BH require verification of voltage thresholds and clock speed limitations.
