24LC01B-E/P

Memory IC Overview

The Microchip Technology 24LC01B-E/P is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C serial interface. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, with maximum active current of 3 mA and standby current of 5 µA at extended temperatures. It offers hardware write protection via the WP pin, an 8-byte page write buffer, and data retention exceeding 200 years. The component is housed in an 8-lead PDIP package and is rated for industrial temperature ranges.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication compatible with standard I2C protocols
• Includes hardware write protection to inhibit memory writes when the WP pin is tied high
• Features Schmitt trigger inputs and noise suppression filters for reliable operation on noisy buses
• Provides an 8-byte page write buffer to optimize data transfer efficiency

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control units needing durable memory for sensor calibration values
• Low-voltage electronic devices utilizing I2C bus architectures
• Automotive applications requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'E' designation indicates Extended temperature range capability (-40°C to +125°C), while 'P' specifies the 8-lead PDIP package. Confirm compliance with RoHS standards and ensure the voltage requirements align with the 2.5V minimum operating threshold defined for this specific part variant.

Memory IC Selection Notes

Select this component when a robust, through-hole EEPROM is required for environments demanding extended temperature stability. The 24LC01B-E/P is suitable for designs where hardware write protection is necessary to prevent accidental data corruption. Ensure the system voltage remains above 2.5 V to maintain the specified 400 kHz clock frequency performance.

Memory IC Part Context

This device belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA01 and 24FC01 models but is distinguished by its specific 2.5 V to 5.5 V operating voltage range. The family is designed for cost-effective embedded memory solutions across various consumer and industrial sectors.

Memory IC Replacement Considerations

The 24LC01B-I/P serves as a direct functional substitute within the same package type, differing only in the Industrial temperature rating (-40°C to +85°C). Cross-referencing with other manufacturers requires verifying I2C compatibility and voltage thresholds.
