24LC02BH-I/MS

Memory IC Overview

The Microchip Technology 24LC02BH-I/MS is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write protection for the upper half of the memory array (addresses 80h-FFh). It utilizes low-power CMOS technology with a maximum read current of 1 mA and standby current of 1 µA. The component is housed in an 8-lead MSOP package and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• I²C compatible two-wire serial interface supporting 100 kHz and 400 kHz clock rates
• Schmitt trigger inputs on SDA and SCL lines for noise suppression
• Output slope control designed to eliminate ground bounce

Memory IC Applications

• Data storage in battery-powered devices requiring low standby current
• Industrial systems needing hardware-level write protection for critical data segments
• Embedded controllers utilizing I²C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade and package type, as these define the specific electrical and physical characteristics. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement. Ensure the supply chain source provides valid traceability codes consistent with Microchip standards.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution with hardware write protection is required. It is suitable for applications operating between 2.5V and 5.5V where I²C compatibility is necessary. Consider the MSOP package for space-constrained surface-mount designs. Verify that the 400 kHz speed meets system timing requirements.

Memory IC Part Context

This part belongs to the 24XX02H family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA02H but differs in minimum operating voltage. The family offers various package options including SOIC, TSSOP, and DFN, catering to diverse PCB layout needs while maintaining consistent I²C interface functionality.

Memory IC Replacement Considerations

The 24LC02B series serves as a direct functional replacement within the same product line. Cross-referencing datasheets is recommended to ensure identical package dimensions and pinout configurations.
