24VL024/SN

Memory IC Overview

The Microchip Technology 24VL024/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 I²C™ compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features Schmitt trigger inputs for noise suppression, hardware write protection for the entire array, and output slope control to eliminate ground bounce. It provides more than one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection capability for the entire memory array via dedicated pin
• Low-power CMOS technology enabling operation down to 1.5V with minimal active and standby currents
• I²C compatible 2-wire serial interface supporting standard and fast mode clock frequencies
• Schmitt trigger inputs combined with filter circuits to suppress noise spikes on the bus

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Battery-powered devices utilizing low standby current capabilities
• Industrial applications necessitating robust noise immunity on communication buses
• Multi-device bus architectures expanding contiguous address space

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOIC-8 package type. Confirm the operational voltage range requirements align with the 1.5V to 3.6V specification. Ensure the application design accounts for the hardware write protection functionality available exclusively on this variant compared to other family members.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM is required with hardware-level write protection for the full array. It is suitable for designs needing operation at voltages as low as 1.5V while maintaining compatibility with standard I²C protocols. Consider the SOIC-8 package constraints and ensure the system can support the specified maximum clock frequency of 400 kHz.

Memory IC Part Context

This part belongs to the 24VL024/24VL025 series of 2 Kbit Serial EEPROMs manufactured by Microchip Technology. The series is characterized by its ability to operate at low voltages starting from 1.5V. The 24VL024 specifically includes a hardware write protect feature not present in the 24VL025 counterpart, making it distinct within the product line for security-sensitive applications.

Memory IC Replacement Considerations

The 24LC024 serves as a functional replacement but requires a minimum operating voltage of 2.5V. Verify that the target circuit maintains sufficient voltage headroom above 2.5V to ensure reliable operation if substituting this lower-voltage part.
