24LC16BT-E/MC

Memory IC Overview

The Microchip Technology 24LC16BT-E/MC is a 16-Kbit (2K x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz, with a maximum access time of 900 ns. The device utilizes low-power CMOS technology, drawing a maximum active current of 3 mA and standby current of 5 μA at extended temperatures. It offers over one million erase/write cycles and data retention exceeding 200 years. The component is housed in an 8-lead DFN package and is qualified for the extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection via the WP pin allows complete memory array locking when tied to VCC.
• Integrated 16-byte page write buffer enables efficient sequential data storage operations.
• Schmitt trigger inputs and noise filtering circuits ensure reliable signal integrity on noisy buses.
• Self-timed erase/write cycles automatically terminate without requiring external timing control.

Memory IC Applications

• Embedded systems requiring non-volatile parameter storage
• Industrial control units needing high endurance memory
• Automotive electronics compliant with AEC-Q100 standards

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and the 'MC' designation indicates the 8-lead DFN package. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure supply chain sources provide valid traceability codes matching the marking information specified in the datasheet.

Memory IC Selection Notes

Select this component for applications requiring robust data retention and high cycle endurance in harsh thermal environments. The 2.5V minimum operating voltage suits standard logic levels, while the 400 kHz interface speed balances performance with bus stability. Consider the hardware write-protect feature for security-critical data storage requirements where accidental modification must be prevented.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16 and 24FC16 but is distinguished by its 2.5V minimum operating voltage requirement compared to the 1.7V capability of other variants. The device maintains compatibility with standard I²C protocols while offering specialized packaging options like the compact DFN form factor.

Memory IC Replacement Considerations

Direct substitutes include other 24LC16B variants with different temperature grades or packages, such as 24LC16BT-I/MC for industrial temperature ranges. Cross-family replacements like 24AA16 or 24FC16 require verification of voltage level compatibility and clock frequency limits before implementation.
