24LC01BHT-E/MS

Memory IC Overview

The Microchip Technology 24LC01BHT-E/MS 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 with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, supporting up to one million erase/write cycles and retaining data for over 200 years. It includes hardware write-protect functionality for half the array and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection
• Low-power CMOS technology with standby current as low as 1 μA
• I2C compatible 2-wire serial interface with Schmitt trigger inputs
• High reliability with over one million erase/write cycles

Memory IC Applications

• Consumer electronics requiring non-volatile data storage
• Industrial control systems needing parameter retention
• Automotive applications operating within extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the MSOP package type and the 'E' designation indicates the automotive temperature grade (-40°C to +125°C). Confirm RoHS compliance status and ensure the specific tape-and-reel quantity matches production requirements. Cross-reference the full part number against the manufacturer's latest datasheet to validate pinout and electrical specifications before procurement.

Memory IC Selection Notes

Select this component when an I2C interface is required for small capacity non-volatile memory in space-constrained designs. The MSOP package offers a compact surface-mount solution suitable for high-density PCB layouts. Ensure the system voltage remains above 2.5V to maintain the specified 400 kHz clock speed. Consider the automotive temperature rating if the application environment exceeds standard industrial limits.

Memory IC Part Context

This device belongs to the 24LC01BH family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA01H but differs in minimum operating voltage requirements. The family supports various packages including SOIC, TSSOP, and DFN, providing flexibility for different board design constraints while maintaining consistent I2C communication protocols.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24LC01BH series such as 24LC01BT-E/MS or 24LC01BH-E/MS, provided the package and temperature grade match. Verify compatibility with existing firmware addressing schemes and I2C bus timing requirements when swapping between package types.
