24LC02BH-E/MS

Memory IC Overview

The Microchip Technology 24LC02BH-E/MS is a 2 Kbit (256 x 8) serial Electrically Erasable PROM (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I2C compatible two-wire serial interfaces with clock frequencies up to 400 kHz. The device features an 8-byte page write buffer, self-timed erase/write cycles, and hardware write protection for the upper half of the memory array (addresses 80h-FFh). It is housed in an 8-lead MSOP package and is rated for extended industrial temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycle with acknowledge polling capability
• High endurance exceeding one million erase/write cycles

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Calibration data retention in industrial sensors
• Device identification and serial number storage

Memory IC Procurement Notes

Verify that the ordering suffix 'MS' corresponds to the 8-lead MSOP package type required for your PCB layout. Confirm the 'E' suffix indicates the Extended temperature range (-40°C to +125°C), as opposed to the Industrial range. Ensure the design accounts for the 2.5V minimum operating voltage, which differs from lower-voltage variants in the same family.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity with half-array write protection is required. The MSOP package is suitable for space-constrained surface-mount designs. Choose this part over the 24AA02H variant if the system power supply does not drop below 2.5V, as the 24LC02BH offers optimized performance at higher voltages within its specified range.

Memory IC Part Context

This device belongs to the 24XX02H family of 2 Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with other members like the 24LC02B but adds specific half-array write protection capabilities. The family utilizes a standard I2C interface, allowing compatibility with various microcontrollers and host devices without complex protocol drivers.
