24LC16BH-E/SN

Memory IC Overview

The Microchip Technology 24LC16BH-E/SN 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 via a two-wire serial interface compatible with I²C protocols. The device features a 900 ns access time, 3 mA maximum operating current, and 5 µA standby current at extended temperatures. It utilizes an 8-lead SOIC package and functions within an ambient temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array (addresses 400h-7FFh) controlled by the WP pin.
• Self-timed erase/write cycles with a maximum page write time of 5 ms and a 16-byte page write buffer.
• Schmitt trigger inputs and output slope control designed to suppress noise and eliminate ground bounce.
• High reliability specifications including over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters.
• Industrial control devices needing reliable memory in high-temperature environments.
• Consumer electronics utilizing I²C bus architectures for low-power data logging.
• Automotive applications requiring AEC-Q100 qualified components for critical memory functions.

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'SN' denotes the 8-lead SOIC package. Confirm the 'H' variant designation indicates the half-array write-protect feature distinct from standard 24LC16B models. Ensure compatibility with 2.5V minimum supply requirements before integration into lower voltage designs.

Memory IC Selection Notes

Select this component when extended industrial or automotive temperature ranges are required alongside hardware write protection. The 24LC16BH-E/SN is suitable for designs where protecting the upper memory half is necessary without software overhead. Compare against 24LC16BT variants if tape-and-reel packaging is preferred for automated assembly processes instead of tube packaging.

Memory IC Part Context

This part belongs to the 24XX16H family of 16-Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16H and 24FC16H but is distinguished by its 2.5V minimum operating voltage and 400 kHz maximum clock speed. The device integrates high-voltage generators and page latches to facilitate efficient serial data management.
