24VL024H/ST

Memory IC Overview

The Microchip Technology 24VL024H/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 1.5V to 3.6V and supports I2C-compatible 2-wire serial interfaces with maximum clock frequencies of 100 kHz at voltages below 1.8V, and 400 kHz at voltages between 1.8V and 3.6V. The device features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It includes hardware write protection for the upper half of the array and supports page writes of 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
• Features hardware write protection that secures the upper half of the memory array against unintended writes
• Includes Schmitt trigger inputs and spike suppression filters to ensure reliable data transmission in noisy environments
• Allows cascading up to eight devices on the same bus to expand contiguous address space

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial controllers needing hardware-protected configuration parameters
• Sensor nodes utilizing I2C communication protocols
• Portable electronic devices powered by single-cell batteries

Memory IC Procurement Notes

Verify the ordering suffix 'ST' corresponds to the TSSOP package type when sourcing components. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the specific temperature grade matches your application requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component for applications requiring operation down to 1.5V where standard 2.5V EEPROMs are unsuitable. The TSSOP package offers a compact surface-mount solution suitable for space-constrained designs. Consider the half-array write protection feature if security against accidental overwrites is critical for your specific memory layout.

Memory IC Part Context

This part belongs to the 24VL024H family of 2Kb I2C serial EEPROMs manufactured by Microchip Technology. The family shares identical electrical characteristics and functional logic across various package options, including PDIP, SOIC, MSOP, and TDFN. The 'ST' suffix specifically designates the Thin-Shrink Small Outline Package (TSSOP) variant within this product line.

Memory IC Replacement Considerations

Direct replacements include other packages within the same series such as 24VL024H/P (PDIP), 24VL024H/SN (SOIC), or 24VL024H/MY (TDFN). Verify pin compatibility and package dimensions during substitution.
