Memory IC Procurement Notes

Verify the specific suffix 'WI' confirms the SOIC-8 package and Industrial temperature range (-40°C to +85°C). Confirm RoHS compliance and lead finish specifications against current manufacturer documentation, as ordering information may be subject to revision without notice.

Memory IC Selection Notes

Select this component when a 2-Kbit non-volatile memory solution is required with I2C connectivity. Ensure the application environment remains within the specified 1.7 V to 5.5 V supply voltage and -40°C to +85°C operating temperature limits.

Memory IC Part Context

This part belongs to the CAT24Cxx family of serial EEPROMs from onsemi. The family includes variants with capacities ranging from 1-Kbit to 16-Kbit, sharing common functional characteristics such as I2C compatibility and low-power CMOS technology.

Memory IC Replacement Considerations

Compatible substitutes include other 2-Kbit I2C EEPROMs from various manufacturers. Verify pinout compatibility, voltage ranges, and timing requirements before substitution.

Memory IC FAQ

How does the hardware write protection function?

When the WP pin is held HIGH, all write operations are inhibited. The state is strobed on the last falling edge of SCL preceding the first data byte.

What is the maximum page write size?

The device supports a 16-byte page write buffer, allowing up to 16 contiguous bytes to be written in a single internal write cycle.
