24FC512-I/ST14

Memory IC Overview

The Microchip Technology 24FC512-I/ST14 is a 512 Kbit (64K x 8) serial electrically erasable PROM featuring an I2C compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V, supporting maximum clock frequencies of 1 MHz at VCC ≥ 2.5V and 400 kHz at lower voltages. The device utilizes a 14-lead TSSOP package and supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial data transfer with up to 1 MHz clock compatibility under standard operating conditions.
• Includes a 128-byte page write buffer to optimize data writing efficiency and reduce bus overhead.
• Features hardware write protection via the WP pin to prevent accidental data modification.
• Provides Schmitt trigger inputs for enhanced noise suppression and output slope control to minimize ground bounce.

Memory IC Applications

• Personal communication devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial controllers utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets RoHS compliance standards if applicable to your manufacturing process. Ensure that the voltage supply levels in your design align with the specified operational range for optimal performance.

Memory IC Selection Notes

Select this component when a 512 Kbit capacity is required within a compact 14-lead TSSOP footprint. It is suitable for designs needing high-speed I2C communication up to 1 MHz. Consider this part for applications demanding low standby current and robust write protection features.

Memory IC Part Context

This device belongs to the 24XX512 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA512 and 24LC512 but offers higher clock speed capabilities. The family is designed for low-power, advanced applications requiring reliable non-volatile memory solutions.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24FC512 series such as 24FC512-I/SN or 24FC512-I/MF, provided the package type difference is accommodated. Cross-family replacements like 24LC512 are possible but operate at lower maximum clock speeds.
