24FC04-E/SN

Memory IC Overview

The Microchip Technology 24FC04-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 maximum clock frequencies up to 1 MHz across the 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 and standby currents do not exceed 3 µA in extended temperature conditions. Designed for industrial and automotive environments, it operates reliably within an ambient temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed data transfer with a maximum clock frequency of 1 MHz

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade before procurement. Confirm that the Extended temperature rating aligns with system thermal requirements. Ensure compatibility with existing I2C bus configurations regarding voltage levels and pull-up resistor values. Check for any recent Product Change Notifications affecting packaging or manufacturing locations.

Memory IC Selection Notes

Select this component when high-speed 1 MHz operation is necessary compared to slower variants. Choose the PDIP-8 package for through-hole mounting requirements. Consider the 1.7V minimum supply capability for low-voltage system designs. Verify that the extended temperature range meets environmental specifications. Evaluate page write buffer capabilities for efficient data handling needs.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA04 and 24LC04B, which differ primarily in speed and voltage specifications. The 24FC04 specifically offers the highest clock frequency within this group. It shares common architectural features such as the two-wire interface and page write buffers found across the series.

Memory IC Replacement Considerations

The 24FC04-I/SN serves as the industrial temperature variant of this component. Other family members like the 24AA04 and 24LC04B offer different speed or voltage characteristics but share similar interfaces.
