24LC01BHT-I/MS

Memory IC Overview

The Microchip Technology 24LC01BHT-I/MS is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-Wire I²C compatible serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology with a maximum read current of 1 mA and standby current of 1 μA. It includes hardware write-protect functionality for half the array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Hardware write-protect capability allows selective protection of the upper half of the memory array via the WP pin.
• Integrated Schmitt trigger inputs on SDA and SCL lines provide enhanced noise spike suppression.
• Output slope control circuitry minimizes ground bounce effects during high-speed switching operations.

Memory IC Applications

• Non-volatile data storage in industrial monitoring systems
• Configuration parameter retention in embedded controllers
• Calibration data preservation in sensor interfaces

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging as indicated by distributor listings. Confirm the 'I' temperature grade matches the required -40°C to +85°C operational range. Ensure the MSOP-8 package dimensions align with the target PCB footprint constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when half-array write protection is required alongside standard I²C connectivity. The MSOP-8 package offers a compact surface-mount solution suitable for space-constrained designs. Verify compatibility with the system's I²C bus voltage levels, noting the minimum operating voltage is 2.5V.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1 Kbit serial EEPROMs. It shares architectural similarities with other devices in the series but is distinguished by its specific voltage requirements and package type. The 'HT' suffix typically denotes reel packaging, while 'I' indicates the industrial temperature rating.

Memory IC Replacement Considerations

Direct substitutes include other 24LC01BH variants in different packages such as SOIC or TSSOP, provided the pinout remains compatible. Cross-reference with 24LC01B models if half-array write protection is not strictly necessary.
