24FC01-I/ST

Memory IC Overview

The Microchip Technology 24FC01-I/ST is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-wire I2C serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device supports page writes up to 8 bytes and includes hardware write protection via the WP pin. It is housed in an 8-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V
• I2C compatible 2-wire serial interface with Schmitt trigger inputs for noise suppression
• Hardware write-protect capability via the WP pin
• High reliability with over one million erase/write cycles and data retention exceeding 200 years

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter memory in consumer electronics
• Asset tracking and identification systems

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically 'ST' for the 8-lead TSSOP variant. Confirm the temperature grade corresponds to the application environment; 'I' denotes the Industrial range (-40°C to +85°C). Ensure compatibility with the system's I2C bus voltage levels, as the device supports a wide operating range from 1.7V to 5.5V.

Memory IC Selection Notes

Select this component when a small non-volatile memory footprint is required for storing calibration data or user settings. The 1 MHz clock speed offers faster throughput compared to standard 400 kHz EEPROMs. Consider the 8-byte page write buffer for efficient data writing operations. Verify that the 8-lead TSSOP package fits the available PCB space constraints.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA01 and 24LC01B, which share similar interfaces but differ in voltage ranges and clock speeds. The 24FC01 specifically supports higher clock frequencies down to lower voltages compared to other family members.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA01 and 24LC01B, provided their specific voltage and clock frequency requirements align with the design. Cross-referencing datasheets is necessary to confirm pinout compatibility and electrical characteristics match the original design specifications.
