24LC01B/SN

Memory IC Overview

The Microchip Technology 24LC01B/SN is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead SOIC package. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a 2-wire I²C compatible serial interface. The device features Schmitt trigger inputs for noise suppression, hardware write protection, and output slope control to eliminate ground bounce. It offers over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with up to 400 kHz clock frequency
• Includes hardware write-protect capability via the WP pin to inhibit memory writes
• Features Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Microcontroller external configuration storage
• System parameter logging
• User setting preservation

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-lead SOIC package variant. Confirm the temperature grade matches the required operational environment, as industrial ratings differ from extended grades. Ensure the selected part number aligns with the specific voltage requirements of the target system design.

Memory IC Selection Notes

Select this component when a 1 Kbit non-volatile memory solution is required with I²C connectivity. It is suitable for applications needing hardware-level write protection and robust noise immunity. Consider the 8-lead SOIC form factor for surface mount assembly constraints and verify compatibility with the host controller's I²C bus timing specifications.

Memory IC Part Context

This device belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA01 and 24FC01, which share similar interfaces but differ in voltage ranges and clock speeds. The 24LC01B specifically targets standard 2.5V to 5.5V operation environments.

Memory IC Replacement Considerations

Compatible substitutes within the same family include the 24LC01BH and 24LC01BT. Verify package compatibility and temperature range specifications before substitution.
