24LC16B-I/STG

Memory IC Overview

The Microchip Technology 24LC16B-I/STG 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 900 ns access time, a 16-byte page write buffer, and a maximum page write time of 5 ms. It is designed for industrial temperature ranges (-40°C to +85°C) and includes hardware write-protect capabilities.

Memory IC Feature Summary

• Supports bidirectional data transmission using a standard two-wire serial interface protocol.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features a 16-byte page write buffer that allows efficient sequential data storage.
• Provides hardware write protection through the WP pin to inhibit write operations.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices needing parameter retention
• Consumer electronics utilizing low-power memory solutions

Memory IC Procurement Notes

Verify the specific ordering suffix 'STG' against official Microchip documentation to confirm package type and availability. Ensure the component meets the required industrial temperature range specifications. Confirm RoHS compliance status for the specific batch. Check for any automotive AEC-Q100 qualification requirements if applicable to the target application environment.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with I2C interface is required for industrial applications. It is suitable for designs operating between 2.5V and 5.5V. Consider the 8-lead TSSOP package for surface mount assembly. Evaluate the need for hardware write protection and page write buffering for system efficiency.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs from Microchip Technology. The family includes variants like 24AA16 and 24FC16 with different voltage and speed characteristics. The 24LC16B specifically targets applications requiring operation down to 2.5V. The 'I' designation indicates the industrial temperature grade.

Memory IC Replacement Considerations

Compatible substitutes within the same family include 24LC16B-I/SN (SOIC package) and 24LC16B-I/P (PDIP package). Verify pin compatibility and electrical specifications before substitution. Other packages such as MSOP or DFN may also serve as alternatives if form factor changes are acceptable.
