24LC16B-E/MC

Memory IC Overview

The Microchip Technology 24LC16B-E/MC is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. The device features an I²C compatible two-wire serial interface, Schmitt trigger inputs for noise suppression, and hardware write protection via the WP pin. It is designed for extended industrial applications with an operating temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Low-power CMOS technology with standby current of 1 μA maximum
• Hardware write-protect capability when WP pin is tied to VCC
• Schmitt trigger inputs and output slope control for noise immunity
• Self-timed erase/write cycle with 16-byte page write buffer

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control units operating in high-temperature environments
• Consumer electronics utilizing I²C communication protocols
• Automotive electronic modules requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the specific 8-lead DFN package type. Confirm RoHS compliance status and ensure the component meets the required automotive or industrial qualification standards before integration into production designs.

Memory IC Selection Notes

Select this part for applications requiring extended temperature operation up to 125°C. Ensure the system voltage remains within the 2.5V to 5.5V range. Consider the 8-lead DFN footprint constraints during PCB layout. Verify that the I²C bus speed requirements do not exceed 400 kHz at the specified supply voltages.

Memory IC Part Context

This component belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA16 and 24FC16 models but is distinguished by its specific 2.5V minimum operating voltage requirement. The device provides reliable non-volatile storage solutions for various embedded memory needs.

Memory IC Replacement Considerations

Direct replacements include other variants within the 24LC16B series such as 24LC16B-I/SN or 24LC16B-E/ST, provided the package type matches the design constraints. Cross-referencing with 24AA16 or 24FC16 requires verification of voltage compatibility and clock frequency limits.
