24LC01BT-I/MNY

Memory IC Overview

The Microchip Technology 24LC01BT-I/MNY 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 2.5 V to 5.5 V with a maximum clock frequency of 400 kHz. The device utilizes an 8-lead TDFN package and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum active read current of 3 mA, standby current of 1 µA, and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication protocol with Schmitt trigger inputs for noise suppression.
• Includes hardware write-protect functionality via the WP pin to inhibit memory writes when tied high.
• Features an 8-byte page write buffer to optimize data transfer efficiency during programming cycles.

Memory IC Applications

• Non-volatile data storage in industrial control systems
• Configuration parameter retention in embedded devices
• Calibration data logging in sensor modules

Memory IC Procurement Notes

Verify the specific suffix 'MNY' corresponds to the 8-lead TDFN package configuration required for your PCB layout. Confirm that the 'I' designation meets the necessary industrial operating temperature range of -40°C to +85°C for your application environment. Ensure power supply rails remain within the specified 2.5 V to 5.5 V limits to maintain reliable operation.

Memory IC Selection Notes

Select this component when a compact surface-mount EEPROM is required for low-power applications. The 24LC01B series is suitable for designs needing hardware write protection and fast page write capabilities. Consider the TDFN package dimensions against available board space constraints compared to other available packages like SOIC or TSSOP.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA01 and 24FC01, which differ primarily in minimum operating voltage and maximum clock speed. The 24LC01B specifically targets standard 2.5 V to 5.5 V logic levels.

Memory IC Replacement Considerations

Direct substitutes within the same package and specification include the 24LC01BT-E/MNY for extended temperature ranges. Other package alternatives like 24LC01B-I/ST or 24LC01B-I/P are functionally equivalent but require different footprint considerations.
