24LC16BH-I/ST

Memory IC Overview

The Microchip Technology 24LC16BH-I/ST is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with the I²C protocol and operates on a single supply voltage ranging from 2.5V to 5.5V. The device supports clock frequencies up to 400 kHz within this voltage range, with an access time of 900 ns. It includes hardware write protection for half the array, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. The component is available in an 8-lead TSSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection allows selective locking of the upper half of the memory array via the WP pin.
• Integrated Schmitt triggers and input filters suppress noise spikes to ensure stable operation on noisy buses.
• Output slope control mechanisms eliminate ground bounce during signal transitions.
• Self-timed erase/write cycles utilize an internal timer to manage programming duration automatically.

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial controllers needing reliable logging of operational states
• Consumer electronics utilizing low-power serial memory interfaces

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the TSSOP-8 package type and Industrial temperature grade. Confirm compliance with RoHS directives and lead-free manufacturing standards required by your assembly processes. Ensure the voltage supply rails match the 2.5V minimum requirement specified for the 24LC16BH variant. Check for automotive AEC-Q100 qualification if the application demands extended reliability standards beyond standard industrial specifications.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is sufficient and half-array write protection is required. The 2.5V minimum operating voltage distinguishes it from lower-voltage variants like the 24AA16H. The I²C interface simplifies PCB routing by minimizing pin count. Consider the 16-byte page buffer for efficient bulk data writes. Verify that the system clock speed does not exceed 400 kHz at the intended operating voltage.

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 differs in voltage ranges and maximum clock speeds. The 'BH' designation indicates the specific voltage and feature set, while 'I' denotes the industrial temperature rating. The 'ST' suffix identifies the 8-lead Thin-Shrink Small Outline Package.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24XX16H family such as the 24AA16H or 24FC16H, provided voltage and speed requirements align. Cross-referencing pinouts and electrical characteristics is essential due to differences in operating voltage floors and clock limits among family members.
