24LC02BHT-I/SN

Memory IC Overview

The Microchip Technology 24LC02BHT-I/SN 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 offers a maximum access time of 900 ns, a page write buffer of 8 bytes, and a maximum write cycle time of 5 ms. The component is rated for industrial temperatures from -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

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

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Automotive electronics utilizing AEC-Q100 qualified components
• Smart meters and utility devices storing usage data

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the 'SN' suffix indicates the 8-lead SOIC package. Ensure the 'HT' designation aligns with the specific tape-and-reel packaging requirements for automated assembly processes.

Memory IC Selection Notes

Select this part when a 2 Kbit capacity is required alongside hardware-level write protection for critical memory segments. The 400 kHz clock speed supports high-throughput applications. Verify that the 2.5V minimum supply voltage meets the system's power rail specifications compared to lower-voltage alternatives.

Memory IC Part Context

This component belongs to the 24XX02H family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA02H but differs in its minimum operating voltage requirement. The device utilizes a standard I2C protocol for communication and is available in multiple package types including SOIC, TSSOP, and SC-70.

Memory IC FAQ

How does the WP pin function?

Connecting the WP pin to VCC inhibits write operations to the upper half of the memory array (addresses 80h-FFh), while connecting it to VSS enables full read/write access.

What is the page write buffer size?

The device features an 8-byte page write buffer, allowing up to eight consecutive data bytes to be written in a single operation before generating a Stop condition.
