24FC16T-I/ST

Memory IC Overview

The Microchip Technology 24FC16T-I/ST is a 16-Kbit (2K x 8) serial electrically erasable programmable read-only memory (EEPROM). It features an I²C two-wire serial interface with a maximum clock frequency of 1 MHz across the full operating voltage range. The device operates on a single supply voltage from 1.7V to 5.5V and supports page write operations with a 16-byte buffer. It is housed in an 8-lead TSSOP package and is rated for industrial temperature ranges.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication compatible with standard bus protocols
• Includes a 16-byte page write buffer to optimize data transfer efficiency
• Provides hardware write protection via the WP pin to secure memory contents
• Features Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple form factors. Confirm the temperature grade corresponds to the intended operational environment. Ensure the voltage requirements align with the system design, noting the wide operating range. Check for any recent product change notifications regarding packaging or material composition updates before finalizing procurement.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is sufficient for the application's data storage needs. Choose this model over variants like the 24LC16B if operation below 2.5V is required, as it supports voltages down to 1.7V. Consider the TSSOP package for surface-mount assembly constraints. Evaluate the 1 MHz speed requirement against lower-speed alternatives if power consumption is a primary concern.

Memory IC Part Context

This device belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16 and 24LC16B but offers distinct electrical characteristics, particularly regarding minimum operating voltage and maximum clock frequency. The family is designed for low-power, non-volatile memory applications where space and energy efficiency are critical.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA16 and 24LC16B, though voltage and speed specifications differ. Verify compatibility with existing firmware addressing schemes, as block selection bits remain consistent across the family.
