24FC08-I/MS

Memory IC Overview

The Microchip Technology 24FC08-I/MS is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four 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 utilizes low-power CMOS technology, ensuring standby current remains at or below 1 µA and read current at 1 mA maximum. It includes a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication across the entire operating voltage range
• Includes a 16-byte page write buffer to optimize data transfer efficiency
• Features hardware write protection controlled by the dedicated WP pin
• Incorporates Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial control applications operating within industrial temperature ranges
• Portable devices utilizing battery power due to low standby current consumption
• Systems requiring hardware-level write protection for critical configuration data

Memory IC Procurement Notes

Verify that the specific order suffix corresponds to the MSOP-8 package type. Confirm the temperature grade 'I' matches the required operational range of -40°C to +85°C. Ensure the design supports the 1.7V minimum supply voltage requirement for this specific variant. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 1 MHz clock speed is necessary at voltages below 2.5V, distinguishing it from the 400 kHz limited 24LC08B. Consider the MSOP-8 package for space-constrained surface-mount designs. Evaluate the need for hardware write protection; if not required, the WP pin can be tied to ground. Compare against the 24AA08 if lower cost is prioritized over the higher 1 MHz speed capability.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24LC08B but offers distinct performance characteristics regarding voltage and speed. The family provides a standardized I²C interface for easy integration into existing bus architectures while offering various packaging options to suit different board layout requirements.

Memory IC Replacement Considerations

The 24LC08B serves as a functional substitute but is limited to 400 kHz operation below 2.5V. The 24AA08 is also compatible but similarly restricted in high-speed performance at lower voltages. Verify that any replacement maintains the same MSOP-8 footprint and electrical specifications to ensure circuit compatibility.
