24FC04-E/MS

Memory IC Overview

The Microchip Technology 24FC04-E/MS is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead MSOP package. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 1 MHz. The device operates on a single supply voltage ranging from 1.7V to 5.5V and supports extended industrial temperature conditions from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer
• Includes hardware write-protect functionality via the WP pin
• Features Schmitt trigger inputs and output slope control for noise suppression

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 specific ordering suffix corresponds to the MSOP package type and Extended temperature grade. Confirm that the required operating voltage range aligns with the 1.7V to 5.5V specification. Ensure the design accommodates the necessary pull-up resistors for the I2C bus lines to meet timing requirements at 1 MHz operation.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C access is required alongside low-voltage operation down to 1.7V. The Extended temperature rating makes it suitable for harsh environments where standard industrial grades are insufficient. The MSOP package offers a compact surface-mount solution for space-constrained designs.

Memory IC Part Context

This part belongs to the 24XX04 family of 4-Kbit serial EEPROMs, which also includes the 24AA04 and 24LC04B variants. Unlike the 24LC04B, which is limited to 400 kHz and 2.5V minimum, the 24FC04 provides enhanced speed and lower voltage capability. The 'E' designation indicates the extended temperature range, while '/MS' specifies the 8-lead MSOP package.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24FC04-I/MS for industrial temperature ranges or other package variations such as 24FC04-P (PDIP) and 24FC04-SN (SOIC). Cross-family replacements like the 24LC04B offer slower speeds but may fit if voltage constraints differ.
