24LC16BHT-E/ST

Memory IC Overview

The Microchip Technology 24LC16BHT-E/ST is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates with a supply voltage range of 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 page write time of 5 ms maximum, an access time of 900 ns, and active read current of 1 mA maximum. It is housed in a 5-lead SOT-23 package and rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection when the WP pin is tied high
• Integrated Schmitt trigger inputs and noise suppression filters for reliable bus operation
• Output slope control designed to eliminate ground bounce during switching
• Self-timed erase/write cycles with automatic acknowledge polling support

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control units needing reliable memory under extended temperature conditions
• Consumer electronics utilizing low-power I²C communication interfaces
• Automotive modules requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify the specific suffix 'HT' indicates tape and reel packaging versus tube options. Confirm the 'E' designation matches the required extended temperature range of -40°C to +125°C. Ensure the voltage rating aligns with the 2.5V minimum requirement for the LC series variant. Check RoHS compliance status if restricted substances are mandated by your assembly process.

Memory IC Selection Notes

Select this component when half-array write protection is necessary without additional logic gates. The SOT-23 package suits space-constrained designs compared to larger SOIC or TSSOP options. Consider the 400 kHz speed limit if higher bus frequencies are required, as other variants may offer 1 MHz support. Verify that the 2.5V minimum operating voltage fits within your system's power rail specifications.

Memory IC Part Context

This part belongs to the 24XX16H family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16H and 24FC16H but differs in voltage ranges and clock speeds. The 24LC16BH specifically targets applications requiring 2.5V operation, distinguishing it from the lower voltage AA and FC series.

Memory IC Replacement Considerations

Direct substitutes include other 24LC16BH variants with different packages such as MSOP or SOIC. Cross-reference with 24LC16BT-I/ST for industrial temperature grades if extended range is not critical. Ensure any replacement maintains the same I²C addressing scheme and page buffer size.
