24LC02BHT-I/LT

Memory IC Overview

The Microchip Technology 24LC02BHT-I/LT is a 2 Kbit (256 x 8) Electrically Erasable PROM featuring a two-wire I2C serial 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-protect functionality 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 a 5-lead SC-70 package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Schmitt trigger inputs on SDA and SCL lines for noise suppression
• Output slope control designed to eliminate ground bounce during switching
• Self-timed erase/write cycles with an 8-byte page write buffer

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in battery-backed circuits

Memory IC Procurement Notes

Verify that the ordering suffix matches the specific package type, as the LT suffix indicates the 5-lead SC-70 package. Confirm the temperature grade corresponds to the required operational environment. Ensure the voltage supply meets the minimum 2.5V requirement for the 24LC02BH series. Check datasheet revisions for any changes in electrical characteristics or packaging specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small data storage needs. The SC-70 package offers space efficiency compared to standard SOIC or PDIP options. The hardware write-protect feature is suitable for applications requiring protection against accidental overwrites of critical configuration data. Verify compatibility with the system's I2C bus voltage levels and pull-up resistor requirements.

Memory IC Part Context

This part belongs to the 24XX02H family of 2 Kbit serial EEPROMs from Microchip Technology. The 'L' in the model number designates the 5-lead SC-70 package variant. The 'I' suffix specifies the industrial temperature range. This family shares functional similarities with other 24LC02 variants but differs in physical footprint and specific voltage thresholds defined by the H-series designation.

Memory IC Replacement Considerations

Direct replacements include other 24LC02BH variants in different packages such as 24LC02BHT-I/OT (SOT-23) or 24LC02BHT-I/MS (MSOP). Cross-referencing pinouts is essential due to the unique pin arrangement of the 5-lead SC-70 package compared to 8-lead alternatives.
