24VL024H/SN

Memory IC Overview

The Microchip Technology 24VL024H/SN is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.5 V to 3.6 V and supports a maximum clock frequency of 400 kHz via a 2-wire I²C compatible interface. The device features Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce, and hardware write protection for the upper half of the array. It includes a page write buffer for up to 16 bytes and is available in an 8-pin SOIC package.

Memory IC Feature Summary

• Supports low-power operation with active current as low as 400 μA and standby current as low as 1 μA.
• Features hardware write protection that prevents writes to the upper half of the memory array when the WP pin is tied high.
• Includes a 16-byte page write buffer to improve bus throughput during sequential data transfers.
• Provides cascading capability allowing up to eight devices to be connected on the same bus using configurable chip select pins.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• I²C bus expansion for contiguous memory addressing across multiple devices
• Industrial applications utilizing hardware write protection for critical data segments

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-pin SOIC package variant. Confirm the operating temperature range matches the industrial specification (-20°C to +85°C). Ensure the design accounts for the 1.5V to 3.6V supply voltage limits and the 400 kHz clock frequency requirement at appropriate voltage levels.

Memory IC Selection Notes

Select this component for designs requiring low-voltage operation down to 1.5V and I²C compatibility. Consider the hardware write protection feature if protecting the upper memory array is necessary. Verify that the 8-pin SOIC package fits the board layout constraints and that the 400 kHz speed meets system timing requirements.

Memory IC Part Context

The 24VL024H belongs to the 24VL024 family of serial EEPROMs manufactured by Microchip Technology. This family is characterized by its ability to operate at voltages as low as 1.5V, making it suitable for battery-powered or energy-efficient applications. The device utilizes CMOS technology to minimize power consumption while maintaining reliable data retention.

Memory IC Replacement Considerations

Check datasheet specifications for direct replacements within the 24LC or 24AA series, noting differences in voltage ranges and interface speeds. Ensure any substitute part supports the required 1.5V minimum operating voltage and I²C protocol compatibility.
