24LC01BT/SN

Memory IC Overview

The Microchip Technology 24LC01BT-I/SN is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-wire I2C serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, offering maximum standby current of 1 µA and active read current of 1 mA. It includes an 8-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead SOIC package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire I2C compatible serial data transmission with host-controlled bus access.
• Features hardware write protection that inhibits all memory writes when the WP pin is tied to VCC.
• Includes internal address pointer for automatic incrementation during sequential read operations.
• Provides acknowledge polling functionality to determine completion of internally timed write cycles.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'SN' denotes the 8-lead SOIC package. Confirm the 'T' indicates tape-and-reel packaging if required for automated assembly. Ensure the voltage rating matches the system's 2.5V minimum requirement, as this variant does not support operation below 2.5V unlike the 24AA01 series.

Memory IC Selection Notes

Select this component when a 1 Kbit non-volatile memory solution is required with standard I2C connectivity. It is suitable for applications needing hardware-level write protection and high endurance. Consider the 8-byte page write buffer for efficient data updates. Verify that the system voltage remains above 2.5V, as lower voltages are not supported by this specific part number compared to the 24AA01.

Memory IC Part Context

This device belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA01 and 24FC01 but differs in operating voltage and clock speed specifications. The 24LC01B variant specifically targets applications requiring a 2.5V to 5.5V supply range and 400 kHz maximum clock frequency, distinguishing it from the wider voltage range of the 24AA01.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC01BT-E/SN for extended temperature ranges or 24LC01-I/PVAO for PDIP packaging alternatives.
