24VL024/ST

Memory IC Overview

The Microchip Technology 24VL024/ST 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 maximum clock frequencies of 100 kHz at voltages below 1.8 V, and 400 kHz at voltages between 1.8 V and 3.6 V. The device features Schmitt trigger inputs for noise suppression, hardware write protection for the entire array, and a page write buffer capable of storing up to 16 bytes.

Memory IC Feature Summary

• Supports low-power operation with active current as low as 400 μA and standby current down to 1 μA.
• Includes hardware write protection that secures the entire memory array when the WP pin is tied high.
• Features output slope control designed to eliminate ground bounce during switching operations.
• Provides cascading capability allowing up to eight devices to be connected on the same bus.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial applications utilizing I²C bus communication protocols
• Battery-powered devices needing extended data retention capabilities

Memory IC Procurement Notes

Verify the specific package suffix matches the required form factor, as ST denotes TSSOP-8. Confirm the operating voltage range aligns with system requirements, noting reduced clock speeds below 1.8 V. Ensure the design accounts for the hardware write protect functionality inherent to the 24VL024 model variant.

Memory IC Selection Notes

Select this component for designs requiring robust noise immunity via Schmitt triggers and precise low-voltage operation down to 1.5 V. Consider the 16-byte page write buffer for efficient data throughput. Verify that the TSSOP-8 package dimensions fit the available PCB space constraints.

Memory IC Part Context

This part belongs to the 24VL024 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24VL025 but includes dedicated hardware write protection circuitry. The device is designed for integration into compact electronic systems requiring reliable, non-volatile memory storage.

Memory IC Replacement Considerations

Direct substitutes include other 24VL024 variants with different package suffixes such as SN (SOIC), MSOP, or P (PDIP). Cross-family replacements like the 24LC024 require verification of voltage compatibility, as they typically operate at higher minimum voltages.
