24LC01BT-E/LT

Memory IC Overview

The Microchip Technology 24LC01BT-E/LT is a 1 Kbit (128 x 8) Electrically Erasable PROM 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 with a maximum active current of 3 mA and standby current of 5 µA at extended temperatures. It includes an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in a compact SC-70-5 package and is rated for operation across an extended temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication compatible with standard I2C protocols.
• Includes hardware write protection capability controlled by the dedicated WP pin.
• Features internal address pointer for sequential read and write operations.
• Incorporates Schmitt trigger inputs and output slope control for signal integrity.

Memory IC Applications

• Non-volatile data storage in embedded systems
• Configuration parameter retention in industrial controllers
• Calibration data memory for sensor modules

Memory IC Procurement Notes

Verify the specific ordering suffix 'LT' corresponds to the SC-70-5 package and 'E' indicates the extended temperature grade (-40°C to +125°C). Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the application circuit provides appropriate pull-up resistors on SDA and SCL lines for the selected bus speed. Check for any recent Product Change Notifications regarding packaging or marking updates.

Memory IC Selection Notes

Select this component when a small surface-mount footprint is required for low-capacity non-volatile storage. The extended temperature rating makes it suitable for harsh environments where standard industrial grades are insufficient. Consider the 8-byte page write buffer for efficient data logging applications. Verify that the system voltage remains above 2.5V to ensure proper operation of the 24LC01B variant.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs from Microchip Technology. The family shares common functional characteristics but varies in voltage ranges and packages. The 24LC01B specifically requires a minimum of 2.5V, distinguishing it from the 1.7V capable 24AA01 and 24FC01 models. The 'BT' designation typically implies tape and reel packaging for automated assembly.

Memory IC Replacement Considerations

Direct replacements include other 24LC01B variants in different packages such as SOIC or TSSOP, provided pin compatibility is verified. Cross-referencing with 24AA01 or 24FC01 requires attention to voltage level differences and potential timing variations.
