24LC01BH-E/ST

Memory IC Overview

The Microchip Technology 24LC01BH-E/ST is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and utilizes low-power CMOS technology with a maximum active current of 1 mA and standby current of 1 μA. The device supports clock frequencies up to 400 kHz, offers hardware write-protect for half the array via the WP pin, and provides over one million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array
• Schmitt trigger inputs and output slope control for noise suppression
• Supports standard and fast mode I2C bus protocols
• High ESD protection rating exceeding 4,000V

Memory IC Applications

• Embedded systems requiring non-volatile configuration storage
• Industrial control devices needing parameter logging
• Automotive electronics operating in high-temperature environments
• Smart meters and utility monitoring equipment

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status and lead-free manufacturing details directly with the manufacturer or authorized distributors. Ensure the selected variant aligns with the system's voltage requirements and physical footprint constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an industrial or automotive temperature range is required alongside a compact surface-mount TSSOP package. The 24LC01BH-E/ST is suitable for designs needing half-array write protection and robust noise immunity. Consider page write capabilities for efficient data handling in applications requiring frequent updates to small data sets.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1K I2C Serial EEPROMs. It shares architectural similarities with other members like the 24LC01BHT-E/ST but differs in specific package configurations and temperature ratings. The 'E' suffix denotes the Automotive temperature grade (-40°C to +125°C), while 'I' indicates Industrial grade.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24LC01BH family such as 24LC01BH-I/SN or 24LC01BH-E/MNY, provided the package and temperature specifications match the design requirements.
