24LC02BHT-E/MNY

Memory IC Overview

The Microchip Technology 24LC02BHT-E/MNY is a 2 Kbit (256 x 8) serial EEPROM featuring an I2C-compatible two-wire interface. It operates within a supply 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) via the WP pin. It utilizes low-power CMOS technology with a maximum read current of 1 mA and standby current of 1 µA. The component offers over one million erase/write cycles, data retention exceeding 200 years, and operates across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array
• Schmitt trigger inputs for noise suppression on SDA and SCL lines
• Output slope control to eliminate ground bounce
• Self-timed erase/write cycle with page write capability

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter retention in automotive electronics

Memory IC Procurement Notes

Verify that the ordering suffix MNY corresponds to the 8-lead MSOP package as specified in the manufacturer's selection table. Confirm the E suffix indicates the extended temperature grade (-40°C to +125°C). Ensure the device meets RoHS compliance requirements for your specific application standards before finalizing procurement.

Memory IC Selection Notes

Select this part when a compact surface-mount solution is required for non-volatile data storage in high-temperature applications. The MSOP package provides space efficiency compared to SOIC or PDIP options. The extended temperature rating makes it suitable for harsher operating conditions than standard industrial grade parts.

Memory IC Part Context

This component belongs to the 24XX02H family of 2 Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA02H but differs in minimum operating voltage, requiring 2.5V rather than 1.7V. The family is designed for applications needing reliable, low-power data retention with simple serial interface connectivity.

Memory IC Replacement Considerations

Compatible substitutes include other 24LC02BH variants with different packages such as SN (SOIC), ST (TSSOP), or LT (SC-70), provided the pinout and electrical specifications remain identical. Verify package dimensions and lead pitch compatibility during replacement.
