24LC01B-I/MS

Memory IC Overview

The Microchip Technology 24LC01B-I/MS is a 1 Kbit (128 x 8-bit) Electrically Erasable PROM (EEPROM) housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features industrial temperature range operation from -40°C to +85°C, low standby current of 1 µA, and hardware write protection via the WP pin.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial I2C compatible interface for data transfer
• Includes hardware write-protect capability to inhibit memory writes when WP pin is tied high
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Microcontroller external non-volatile data storage
• System configuration parameter retention
• User setting persistence in embedded devices

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the 'I' designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure compatibility with the system's I2C bus voltage levels and timing requirements before integration.

Memory IC Selection Notes

Select this component for applications requiring small surface-mount packaging and standard I2C communication. It is suitable for systems operating at 2.5V or higher where moderate speed and reliable non-volatile storage are needed. Consider alternative packages if through-hole mounting or different thermal ranges are required.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA01 and 24FC01 but differs in minimum operating voltage and maximum clock frequency specifications. The MSOP package provides a compact solution for space-constrained designs.

Memory IC Replacement Considerations

Direct replacements include other 24LC01B variants with different packages such as 24LC01B-I/SN (SOIC) or 24LC01B-I/ST (TSSOP), provided the pinout and electrical characteristics remain compatible with the existing design.
