24FC01T-I/ST

Memory IC Overview

The Microchip Technology 24FC01T-I/ST is a 1 Kbit (128 x 8) serial EEPROM featuring an I2C-compatible 2-wire 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 utilizes low-power CMOS technology, drawing a maximum active read current of 1 mA and standby current of 1 µA at industrial temperatures. It includes an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead TSSOP package and supports industrial temperature ranges.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication across the full operating voltage range
• Includes an 8-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 signal integrity

Memory IC Applications

• Low-power personal communication devices requiring non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing standard I2C bus architectures
• Embedded systems requiring hardware-level write protection mechanisms

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and packaging format. Confirm the device meets the necessary automotive or industrial qualification standards if applicable to the end application. Ensure compatibility with the host controller's I2C voltage levels and pull-up resistor requirements before integration.

Memory IC Selection Notes

Select this component when operation below 2.5V is required alongside high-speed 1 MHz performance. The 24FC01 series is distinct from the 24LC01B, which is limited to 400 kHz and higher minimum voltages. Consider the 8-byte page buffer size for write optimization and verify that the 8-lead TSSOP package fits the available PCB footprint 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 such as the 24AA01 and 24LC01B, which share similar memory organization but differ in speed and voltage specifications. The 'T' suffix indicates tape and reel packaging, while 'I' denotes the industrial temperature rating.

Memory IC Replacement Considerations

Direct functional replacements within the same speed and voltage profile include other 24FC01 variants with different packages, such as 24FC01-E/MS. Cross-family replacements like the 24LC01B offer lower speeds and higher minimum voltages, requiring circuit adjustments.
