24LC08BHT-I/MNY

Memory IC Overview

The Microchip Technology 24LC08BHT-I/MNY is an 8 Kbit Electrically Erasable PROM organized as four blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5 V to 5.5 V and supports a maximum clock frequency of 400 kHz via a 2-Wire Serial Interface compatible with I²C™. The device features a typical page write time of 3 ms, a 16-byte page write buffer, and hardware write-protect capability for half the array (addresses 200h-3FFh). It is housed in an 8-lead TDFN package and rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write-protect functionality allows locking the upper half of the memory array against modification while maintaining read access.
• Integrated 16-byte page write buffer enables efficient data transfer by storing multiple bytes before initiating an internal self-timed write cycle.
• Schmitt trigger inputs on SDA and SCL lines provide noise suppression and improved spike filtering for reliable communication on noisy buses.

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings or event timestamps
• Configuration parameter storage in embedded controllers where specific memory sections must be protected from accidental writes
• Industrial control units utilizing I²C bus architectures for low-power serial memory expansion

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific revision level against the manufacturer datasheet DS20002084B to ensure compatibility with existing firmware drivers. Check for any recent Product Change Notifications regarding assembly sites or material composition updates prior to finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is needed for 8 Kbit capacity with dedicated hardware write protection. Ensure the system power supply remains within the 2.5 V to 5.5 V range to meet electrical specifications. Consider the TDFN package dimensions for PCB layout constraints and verify that the I²C bus pull-up resistors are appropriate for the 400 kHz operating speed.

Memory IC Part Context

This part belongs to the 24AA08H/24LC08BH family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other devices in the series but is distinguished by its specific voltage requirements and package configuration. The 'I' designation indicates industrial temperature rating, while 'MNY' specifies the TDFN-8 package variant.

Memory IC Replacement Considerations

Direct pin-compatible substitutes within the same family include 24LC08BT-I/MNY and 24LC08BHT-I/ST, provided the package type matches the design requirements. Verify voltage ranges and temperature grades when cross-referencing with other 8 Kbit I²C EEPROMs from different manufacturers.
