24LC16B-E/SN

Memory IC Overview

The Microchip Technology 24LC16B-E/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features a two-wire serial interface compatible with I²C protocols, utilizing Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It supports hardware write protection via the WP pin and includes a 16-byte page write buffer. The component is housed in an 8-lead SOIC package and is rated for extended temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling standby currents as low as 1 μA
• Hardware write protection capability through the dedicated WP pin
• Self-timed erase/write cycles with automatic termination
• High reliability with over one million erase/write cycle endurance

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control units operating in high-temperature environments
• Consumer electronics utilizing I²C communication buses
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the SOIC-8 package type. Confirm RoHS compliance status and ensure the specific revision matches project requirements. Cross-reference the manufacturer part number with official datasheets to validate electrical characteristics before finalizing procurement orders.

Memory IC Selection Notes

Select this component when extended industrial temperature ranges are required alongside standard I²C compatibility. Ensure system voltage remains within the 2.5V to 5.5V operational window. Consider the 16-byte page write buffer size for efficient data throughput. Verify that the hardware write protect feature aligns with system security needs.

Memory IC Part Context

This EEPROM belongs to the 24XX16 family, which also includes the 24AA16 and 24FC16 variants. While sharing similar architecture, the 24LC16B series is distinguished by its minimum 2.5V operating voltage requirement compared to other family members that support lower voltages. The 'E' suffix specifically denotes the extended temperature grade suitable for harsher environmental conditions.

Memory IC Replacement Considerations

Direct replacements include other 24LC16B variants with different temperature grades or packages, such as 24LC16B-I/SN for industrial temperatures. Cross-family substitutes like 24AA16 or 24FC16 require verification of voltage compatibility and clock speed limitations.
