24LC16B-I/SN

Memory IC Overview

The Microchip Technology 24LC16B-I/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 2.5 V to 5.5 V and supports a maximum clock frequency of 400 kHz via a two-wire I²C compatible serial interface. The device features an access time of 900 ns, a page write buffer for up to 16 bytes, and hardware write protection. It is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling standby currents as low as 1 μA
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycles with automatic termination
• Hardware write-protect capability via the WP pin

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating in noisy environments
• Consumer electronics utilizing I²C communication protocols
• Automotive electronic modules requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm compliance with RoHS standards and ensure the component meets the necessary automotive or industrial qualification requirements for your specific application environment before finalizing procurement.

Memory IC Selection Notes

Select this component when a 16 Kbit capacity is required with I²C interface compatibility. Ensure the system voltage supports the minimum 2.5 V operation threshold. Consider the 8-lead SOIC package dimensions for PCB layout constraints and verify that the 400 kHz bus speed aligns with the master controller's capabilities.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA16 and 24FC16, which share similar architectural features but differ in operating voltage ranges and maximum clock frequencies. The 24LC16B specifically targets applications requiring 2.5 V to 5.5 V operation.

Memory IC Replacement Considerations

Direct substitutes include other 24LC16B variants in different packages, such as 24LC16B-I/MS (MSOP) or 24LC16B-I/P (PDIP). Cross-family replacements like 24AA16 or 24FC16 require verification of voltage compatibility and clock speed limitations.
