24LC01BHT-I/SN

Memory IC Overview

The Microchip Technology 24LC01BHT-I/SN 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, providing a maximum read current of 1 mA and standby current of 1 μA. It supports page writes of up to 8 bytes and includes hardware write-protect functionality for the upper half of the memory array.

Memory IC Feature Summary

• Hardware Write-Protect: Enables protection of the upper half of the memory array (addresses 40h-7Fh) via the WP pin.
• I²C Compatibility: Supports bidirectional data transfer using standard Start and Stop conditions with Acknowledge polling.
• Noise Suppression: Features Schmitt Trigger inputs and output slope control to eliminate ground bounce and suppress noise spikes.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial devices needing reliable data retention in noisy environments
• Low-power battery-operated equipment utilizing I²C communication

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging as indicated by distributor specifications. Confirm the 'I' temperature grade matches industrial requirements (-40°C to +85°C). Ensure the SOIC-8 package dimensions align with your PCB footprint design constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM with hardware write-protection capabilities is required. It is suitable for applications operating between 2.5V and 5.5V where low standby power consumption is critical. Choose this part over the 24AA01H variant if the system voltage does not drop below 2.5V, as the 24LC01BH series offers optimized performance within this specific voltage range.

Memory IC Part Context

This component belongs to the 24AA01H/24LC01BH family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but differs in voltage ranges and temperature grades. The 24LC01BH specifically targets industrial applications requiring operation down to 2.5V, distinguishing it from the lower-voltage 24AA01H series.

Memory IC Replacement Considerations

Direct substitutes include other 24LC01BH variants with different packages, such as 24LC01BH-E/MNY or 24LC01BH-I/MS, provided the package type change is acceptable. Cross-reference with 24AA01H parts only if the application voltage remains above 2.5V throughout operation.
