24FC08T-I/OT

Memory IC Overview

The Microchip Technology 24FC08T-I/OT 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 a supply voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, drawing a maximum active current of 1 mA and standby current of 1 µA at industrial temperatures. It includes a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 5-lead SOT-23 package.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock frequencies reaching 1 MHz
• Includes a 16-byte page write buffer to optimize data transfer efficiency
• Provides hardware write protection through the dedicated WP pin
• Features Schmitt trigger inputs on SDA and SCL lines for enhanced noise immunity

Memory IC Applications

• Personal communications devices requiring non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Low-power embedded applications operating on single supplies down to 1.7V

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOT-23 package configuration and the Industrial temperature grade. Confirm that the required clock frequency aligns with the device's 1 MHz capability. Ensure the application design accounts for the hardware write protect functionality if permanent data storage is necessary. Check for any specific RoHS compliance documentation requirements relevant to the manufacturing batch.

Memory IC Selection Notes

Select this component when an 8-Kbit capacity is sufficient for the application's data storage needs. Choose this part over variants with lower clock speeds if system timing requires operation at 1 MHz. Consider the SOT-23 package dimensions against available PCB space constraints. Verify that the 1.7V minimum supply voltage meets the lowest operating voltage of the target system.

Memory IC Part Context

This EEPROM belongs to the 24XX08 family, which also includes the 24AA08 and 24LC08B. Unlike the 24LC08B, which is limited to 2.5V minimum operation, the 24FC08 supports voltages down to 1.7V. It differs from the 24AA08 by offering a higher maximum clock frequency of 1 MHz compared to 400 kHz. All variants share similar physical footprints but differ in electrical specifications.

Memory IC Replacement Considerations

Direct substitutes include other 24FC08 variants with different packages such as 24FC08T-I/SN or 24FC08T-E/ST. Cross-family replacements like the 24LC08BT require verification of the minimum supply voltage and clock speed limitations.
