24LC02BH-E/P

Memory IC Overview

The Microchip Technology 24LC02BH-E/P is a 2 Kbit (256 x 8) serial EEPROM featuring an I2C-compatible two-wire 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) via the WP pin. It utilizes low-power CMOS technology with a maximum standby current of 1 µA and read current of 1 mA. The component offers over one million erase/write cycles, data retention exceeding 200 years, and ESD protection greater than 4,000V.

Memory IC Feature Summary

• Hardware write protection mechanism for the upper half of the memory array
• I2C compatible bidirectional serial data transmission protocol
• Schmitt trigger inputs on SDA and SCL pins for noise suppression
• Self-timed erase and write cycle with page write buffer capability

Memory IC Applications

• Data storage in industrial control systems requiring extended temperature operation
• Configuration parameter retention in automotive electronic modules
• Non-volatile memory backup for embedded microcontroller applications
• Device identification and calibration data storage in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature grade (-40°C to +125°C) and 'P' indicates the 8-Lead PDIP package. Confirm the specific datasheet revision matches the required electrical characteristics. Ensure the supply chain source provides documentation confirming RoHS compliance and AEC-Q100 qualification status as specified by the manufacturer.

Memory IC Selection Notes

Select this component when an application requires hardware-level write protection for critical memory segments without software overhead. The Extended temperature rating makes it suitable for environments exceeding standard industrial limits. The PDIP package is appropriate for through-hole prototyping or manufacturing processes where surface-mount assembly is not utilized. Verify that the system power supply remains stable above 2.5V to ensure proper operation at the specified 400 kHz clock speed.

Memory IC Part Context

This part 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 requirements. The family supports multiple package options including SOIC, TSSOP, MSOP, and SC-70. The 24LC02BH variant specifically targets applications needing robust performance across both industrial and extended temperature ranges while maintaining compatibility with standard I2C bus protocols.

Memory IC Replacement Considerations

The 24LC02B-I/P serves as a direct substitute for applications limited to the Industrial temperature range (-40°C to +85°C). Other members of the 24LC02B series may be considered if package type or temperature grade variations are acceptable for the design.
