24LC01BH-E/SN

Memory IC Overview

The Microchip Technology 24LC01BH-E/SN 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 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes Low-Power CMOS technology, ensuring low standby and active currents. It includes hardware write-protect functionality for half the array and offers high endurance exceeding one million erase/write cycles with data retention over 200 years.

Memory IC Feature Summary

• Hardware Write-Protect: Enables selective protection of the upper half of the memory array via the WP pin.
• I²C Compatibility: Supports standard and fast mode communication protocols with Schmitt trigger inputs for noise suppression.
• High Endurance: Designed for reliable long-term operation with over one million write/erase cycles.
• Low Power Consumption: Utilizes CMOS technology to minimize active and standby current requirements.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control devices needing reliable data logging
• Automotive electronics operating in extended temperature environments

Memory IC Procurement Notes

Verify that the specific suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C) rather than the Industrial grade ('I'). Confirm the package type matches the required PCB footprint, as this part number specifies the SOIC-8 package. Ensure the design supports the 2.5V minimum supply voltage requirement for this specific variant.

Memory IC Selection Notes

Select this component when automotive-grade temperature stability is required alongside I²C connectivity. Compare against the 24AA01H series if lower voltage operation down to 1.7V is necessary, noting the 24LC01BH requires a minimum of 2.5V. Consider the page write capability for efficient data block transfers within the application constraints.

Memory IC Part Context

This component belongs to the 24XX01H family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA01H but differs in its minimum operating voltage specifications. The family is designed for applications requiring small memory footprints with robust data retention characteristics.
