24LC01BHT-E/SN

Memory IC Overview

The Microchip Technology 24LC01BHT-E/SN 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 a maximum clock frequency of 400 kHz. The device utilizes automotive-grade temperature specifications, functioning reliably between -40°C and +125°C. Key electrical parameters include a typical write cycle time of 3 ms, an access time of 900 ns, and a standby current of 1 μA maximum.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection via the WP pin
• Schmitt trigger inputs with noise suppression for reliable data transmission
• Page write capability allowing up to 8 bytes of data transfer in a single operation
• Output slope control designed to eliminate ground bounce during switching

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control units operating in high-noise environments
• Automotive electronic modules demanding extended temperature ranges
• Consumer devices utilizing low-power I²C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging and 'SN' indicates the SOIC-8 package. Confirm the 'E' suffix aligns with the required automotive temperature grade (-40°C to +125°C). Ensure compatibility with the specific I²C bus voltage levels used in the target application circuit before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an I²C EEPROM with hardware write-protect features is required for automotive or industrial applications. The SOIC-8 surface mount package facilitates automated assembly processes. Consider the 400 kHz clock speed for faster data throughput compared to standard 100 kHz variants. Verify power consumption requirements against the specified active and standby current limits.
