24LC04B-I/ST16KVAO

Memory IC Overview

The Microchip Technology 24LC04B-I/ST16KVAO is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) utilizing a two-wire serial interface compatible with I²C protocols. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz in industrial temperature environments (-40°C to +85°C). The device features a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. Key electrical characteristics include a maximum active read current of 1 mA and standby current of 5 µA at extended temperatures.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin to inhibit memory writes
• 16-byte page write buffer for efficient data transfer operations
• Schmitt trigger inputs and filter circuits for enhanced noise immunity

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify the specific suffix '16KVAO' against official Microchip documentation to confirm package type and marking details. Ensure compatibility with standard I²C bus pull-up resistor values for the target operating frequency. Confirm that the industrial temperature grade meets the environmental requirements of the intended deployment scenario.

Memory IC Selection Notes

Select this component when a 4-Kbit EEPROM with I²C interface is required for industrial applications. It is suitable for designs needing hardware write protection and low standby power consumption. Verify that the system voltage remains above 2.5V to ensure proper operation within the specified electrical limits.

Memory IC Part Context

This part belongs to the 24XX04 family of serial EEPROMs from Microchip Technology. The family includes variants like the 24AA04 and 24FC04, which differ primarily in minimum operating voltage and maximum clock speed. The 24LC04B specifically targets applications requiring a 2.5V minimum supply voltage while maintaining compatibility with standard I²C communication protocols.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC04B-I/ST or other packages such as MSOP or SOIC. Cross-vendor equivalents like the AT24C04 may be considered if pinout and timing parameters are verified.
