24LC02BT-I/LT

Memory IC Overview

The Microchip Technology 24LC02BT-I/LT is a 2-Kbit (256 x 8) serial EEPROM utilizing 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 features a maximum access time of 900 ns and a page write time of 5 ms. It is housed in a 5-lead SC-70 package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Includes hardware write protection via the WP pin to inhibit memory writes when tied high
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'LT' corresponds to the SC-70-5 package type as specified in the manufacturer's documentation. Confirm the 'I' designation indicates the industrial temperature grade (-40°C to +85°C). Ensure the supply voltage meets the minimum 2.5V requirement for the 24LC02B series, distinct from lower-voltage variants like the 24AA02.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with low active current consumption. The 256-byte organization suits small data sets. Consider the SC-70 package for space-constrained designs. Verify compatibility with the system's I²C bus speed limits and ensure adequate pull-up resistors are present on the SDA and SCL lines for reliable operation at 400 kHz.

Memory IC Part Context

This part belongs to the 24LC02B family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA02 and 24FC02 but differs in operating voltage and maximum clock frequency specifications. The 24LC02B is optimized for 2.5V to 5.5V operations, whereas other family members support lower voltages or higher speeds.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers include 24LC02BT-I/MC and 24LC02BT-I/MS. These alternatives offer identical electrical characteristics and functionality but utilize different package types such as DFN or MSOP instead of SC-70.
