24LC01BT-I/OT

Memory IC Overview

The Microchip Technology 24LC01BT-I/OT is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring an I2C compatible 2-wire 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, ensuring standby current remains at or below 1 µA. It includes an 8-byte page write buffer and hardware write protection via the WP pin. The component is housed in a 5-lead SOT-23 package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transmission over a standard two-wire bus protocol with Schmitt trigger inputs for noise suppression.
• Features an internal address pointer that automatically increments during sequential read operations to facilitate continuous data retrieval.
• Includes hardware write protection capability that inhibits all memory write operations when the dedicated pin is connected to the power supply rail.

Memory IC Applications

• Non-volatile data storage for system configuration parameters
• Calibration value retention in embedded sensor modules
• Device identification and serial number logging

Memory IC Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the selected variant matches the required operating voltage and environmental specifications for the target application. Cross-reference datasheet revisions to confirm compatibility with existing design constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small capacity non-volatile storage needs. The SOT-23-5 package offers significant board space savings compared to traditional 8-pin formats. Confirm that the system voltage meets the minimum 2.5V requirement for the 24LC01B series rather than the lower voltage variants available in other product families.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common electrical characteristics and interface protocols but differs in voltage ranges and physical packaging options. The 'I' designation indicates industrial temperature rating, while 'OT' specifies the 5-lead SOT-23 surface mount package configuration.

Memory IC Replacement Considerations

Direct replacements include other 24LC01B variants with different packages such as 24LC01BT-I/SN or 24LC01BT-I/LT. Verify pinout compatibility and ensure the substitute part maintains the same voltage and temperature specifications.
