24LC16B/ST

Memory IC Overview

The Microchip Technology 24LC16B/ST 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 an I²C compatible two-wire serial interface. The device features a 16-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is available in an 8-lead TSSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the specific temperature grade and package type required for your design. Confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the selected variant matches the necessary voltage range and interface speed specifications for your system architecture before finalizing procurement.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM capacity is needed with I²C connectivity. Choose the Industrial (I) grade for environments operating between -40°C and +85°C. Consider the Extended (E) grade if operation up to +125°C is required. Verify that the 2.5V minimum supply voltage aligns with your system's power rails.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA16 and 24FC16, which differ primarily in operating voltage and maximum clock frequency. The 24LC16B specifically targets applications requiring a 2.5V minimum supply voltage while maintaining compatibility with standard I²C protocols.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24XX16 family such as the 24AA16 or 24FC16, provided their voltage and speed requirements match the application. Cross-referencing pinouts and electrical characteristics is essential when substituting with components from different manufacturers.
