24LC01B/WF

Memory IC Overview

The Microchip Technology 24LC01B/WF is a 1 Kbit (128 x 8) Electrically Erasable PROM organized as one block of memory. It features a 2-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz at supply voltages between 2.5V and 5.5V. The device utilizes low-power CMOS technology, ensuring standby currents of 1 µA maximum and active read currents of 1 mA maximum. It includes an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports bidirectional data transmission over a 2-wire serial bus using standard I2C protocol
• Includes an 8-byte page write buffer to optimize write operations across single physical pages
• Features hardware write protection that inhibits all write operations when the WP pin is tied to VCC
• Incorporates Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce

Memory IC Applications

• Data logging in industrial monitoring systems requiring non-volatile storage
• Configuration parameter storage in consumer electronics devices
• Calibration data retention in embedded sensor applications
• Address or identification code storage in I2C bus networks

Memory IC Procurement Notes

Verify the specific suffix 'WF' against official Microchip documentation to confirm package type and availability status. Confirm RoHS compliance requirements match project specifications. Ensure voltage levels align with the 2.5V minimum operating requirement for the 24LC01B series. Check for any product change notifications affecting packaging or manufacturing locations.

Memory IC Selection Notes

Select this component for applications requiring simple I2C connectivity and moderate data retention needs. The 24LC01B series is suitable where a 2.5V minimum supply voltage is acceptable, distinguishing it from lower-voltage variants like the 24AA01. Consider the available package options if space constraints exist, though the WF suffix indicates a specific form factor. Evaluate endurance requirements against the 1 million cycle specification.

Memory IC Part Context

The 24LC01B belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. This family shares common architectural features including the 128x8 memory organization and I2C compatibility. Variants within the family differ primarily in operating voltage ranges and maximum clock frequencies, such as the 24AA01 supporting 1.7V operation or the 24FC01 supporting 1 MHz speeds.
