24LC01BT-I/LT

Memory IC Overview

The Microchip Technology 24LC01BT-I/LT is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes an SC-70-5 surface-mount package and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a standby current of up to 5 µA and an operating current of 3 mA. It offers hardware write protection, self-timed erase/write cycles, and high endurance exceeding one million write cycles.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission via I2C compatible protocol
• Includes hardware write-protect capability through the WP pin for memory security
• Features Schmitt trigger inputs and noise suppression filters for reliable operation
• Provides page write buffer allowing storage of up to 8 bytes per cycle

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in low-power consumer electronics
• Device identification and calibration data storage

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade and package type. Confirm the specific revision level against the manufacturer's latest datasheet to ensure compatibility with design requirements. Check for any recent Product Change Notifications regarding packaging or material composition updates before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact surface-mount EEPROM is required for I2C communication. Ensure the system voltage remains within the 2.5V to 5.5V range. Consider the SC-70-5 package dimensions for PCB layout constraints. Verify that the application does not require voltages below 2.5V, as other variants in the family support lower thresholds.

Memory IC Part Context

This part belongs to the 24LC01B series of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA01 and 24FC01 devices but differs in minimum operating voltage and clock speed specifications. The 'I' designation indicates the industrial temperature range, while 'LT' specifies the SC-70-5 package configuration.

Memory IC Replacement Considerations

Direct substitutes include other 24LC01B variants with different packages such as 24LC01B-I/SN or 24LC01B-I/ST. Cross-family replacements like 24AA01 or 24FC01 are possible if voltage and speed requirements align, though pinouts and electrical limits must be verified.
