24LC02BH-I/P

Memory IC Overview

The Microchip Technology 24LC02BH-I/P 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 utilizes an 8-lead PDIP package for through-hole mounting. Key electrical parameters include a maximum read current of 1 mA, standby current of 1 µA, and write cycle time of 5 ms. It ensures data retention exceeding 200 years and endurance of over 1 million erase/write cycles.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Schmitt trigger inputs on SDA and SCL pins for noise suppression
• Output slope control designed to eliminate ground bounce effects
• Supports acknowledge polling to maximize bus throughput during internal write cycles

Memory IC Applications

• Embedded systems requiring persistent storage for configuration parameters
• Industrial devices needing non-volatile data logging with hardware write protection
• Automotive electronics requiring AEC-Q100 qualified components
• Low-power consumer electronics utilizing I²C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP package type. Ensure the specific part number matches the datasheet DS20002105B for accurate electrical characteristics and pinout definitions before procurement.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is required with hardware write protection for critical data segments. It is suitable for designs operating strictly above 2.5V, as lower voltage operation down to 1.7V is reserved for the 24AA02H variant. Consider the PDIP package only if through-hole assembly is mandated by the mechanical design constraints.

Memory IC Part Context

This device belongs to the 24XX02H series of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA02H but differs in minimum operating voltage specifications. The series is characterized by low-power CMOS technology and compatibility with standard I²C bus protocols, making it a common choice for general-purpose non-volatile memory applications.

Memory IC Replacement Considerations

The 24LC02B is a compatible alternative offering similar functionality but lacks the specific half-array write protection feature found in the BH variant. Verify package compatibility and ensure the replacement meets the required industrial temperature range specifications.
