24LC16BH-E/ST

Memory IC Overview

The Microchip Technology 24LC16BH-E/ST is a 16-Kbit (2K x 8) serial electrically erasable PROM featuring an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing a maximum active read current of 1 mA and standby current of 5 μA at extended temperatures. It includes hardware write protection for the upper half-array (addresses 400h-7FFh), supports page writes up to 16 bytes, and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write protection inhibits write operations to the upper half of the memory array when the WP pin is tied high.
• Integrated Schmitt trigger inputs and output slope control suppress noise spikes and eliminate ground bounce.
• Self-timed erase/write cycle with automatic timing control simplifies host microcontroller software.
• High electrostatic discharge protection rating ensures robustness against handling damage.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control devices needing reliable data logging
• Consumer electronics utilizing I²C bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'ST' denotes the TSSOP-8 package. Confirm the 'H' variant designation indicates the half-array write protect feature distinct from standard models. Ensure compatibility with the 2.5V minimum operating voltage requirement for this specific part number before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required with hardware-level write protection for critical data segments. The extended temperature grade suits environments exceeding standard industrial limits. Verify that the system power supply remains above 2.5V, as lower voltages are not supported by this specific model compared to the 24AA16H series.

Memory IC Part Context

This device belongs to the 24XX16H family of serial EEPROMs from 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 'H' suffix specifically denotes the inclusion of half-array write protection capabilities.
