24VL024T/ST

Memory IC Overview

The Microchip Technology 24VL024T/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 a page write buffer for up to 16 bytes, hardware write protection for the entire array, and an access time of 900 ns. It is housed in an 8-pin TSSOP package.

Memory IC Feature Summary

• Supports low-power operation with active current as low as 400 μA and standby current down to 1 μA.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features a self-timed write cycle with auto-erase capability and a page write buffer for efficient data transfer.
• Provides hardware write protection for the entire memory array via the WP pin.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications with noisy environments
• Consumer electronics utilizing I²C bus communication

Memory IC Procurement Notes

Verify that the specific ordering suffix 'T/ST' corresponds to the TSSOP-8 package type and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance standards and lead-free requirements as specified by the manufacturer. Ensure the operating voltage range aligns with the system's power supply constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM with I²C interface is required for low-voltage applications. It is suitable for designs needing hardware write protection and high endurance. Consider the TSSOP-8 package dimensions and thermal characteristics during PCB layout. Verify compatibility with the system's I²C bus speed requirements across the full operating voltage range.

Memory IC Part Context

This part belongs to the 24VL024/24VL025 family of 2 Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common electrical characteristics and interface protocols but differs in package options and specific feature availability, such as the hardware write protect pin present on the 24VL024 series.

Memory IC Replacement Considerations

Compatible substitutes within the same family include the 24VL024H/P (PDIP), 24VL024/SN (SOIC), and 24VL024HT/MS (MSOP). These alternatives offer identical electrical specifications and functionality but differ in physical package style and mounting method.
