24FC16T-E/ST

Memory IC Overview

The Microchip Technology 24FC16T-E/ST is a 16-Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 1 MHz. The device features a 16-byte page write buffer, hardware write protection via the WP pin, and extended temperature range operation from -40°C to +125°C. Packaged in an 8-lead TSSOP, it offers high endurance exceeding one million erase/write cycles and data retention of over 200 years.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication with Schmitt trigger inputs for noise suppression
• Includes a 16-byte page write buffer to optimize data transfer efficiency
• Provides hardware write protection through the dedicated WP pin
• Operates across an extended industrial temperature range of -40°C to +125°C

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status and ensure the specific revision aligns with design requirements. Check for any recent Product Change Notifications regarding packaging or material updates before finalizing procurement orders.

Memory IC Selection Notes

Select this component when extended temperature performance (-40°C to +125°C) is required alongside high-speed 1 MHz I²C access. Ensure the application utilizes a single supply voltage within the 1.7V to 5.5V range. Verify that the 8-lead TSSOP footprint fits the PCB layout constraints and that hardware write protection logic is implemented if necessary.

Memory IC Part Context

This part belongs to the 24FC16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16 and 24LC16B but is distinguished by its ability to operate at lower voltages down to 1.7V and support higher clock speeds up to 1 MHz. The 'E' designation indicates the extended temperature variant, while '/ST' specifies the 8-lead TSSOP package.

Memory IC Replacement Considerations

Direct substitutes include other 24FC16 variants with different packages such as 24FC16-E/MS or 24FC16-E/SN. Cross-family replacements like 24LC16B are compatible electrically but differ in minimum operating voltage and maximum clock frequency specifications.
