24VL014HT/ST

Memory IC Overview

The Microchip Technology 24VL014HT/ST is a 1 Kbit (128 x 8) serial EEPROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 1.5V to 3.6V and supports clock frequencies of up to 400 kHz, with 100 kHz compatibility at voltages below 1.8V. The device includes hardware write protection for the upper half of the memory array via the WP pin.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.5V with minimal active and standby currents
• Hardware write protection mechanism that secures the upper half of the memory array against unintended writes
• Integrated Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce

Memory IC Applications

• Battery-powered portable devices requiring low standby current
• Systems needing hardware-protected storage for critical configuration data
• Embedded applications utilizing standard I²C bus communication protocols

Memory IC Procurement Notes

Verify the specific suffix 'HT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the operating voltage range aligns with the system's power supply rails, particularly noting the frequency limitations when VCC falls below 1.8V. Ensure the design accommodates the MSOP-8 package dimensions and thermal characteristics specified in the datasheet.

Memory IC Selection Notes

Select this component for designs prioritizing ultra-low power consumption and robust noise immunity in constrained voltage environments. The integrated hardware write protection simplifies circuit design by removing the need for software-based safeguards for specific memory regions. Verify that the maximum clock frequency requirements are compatible with the available supply voltage levels.

Memory IC Part Context

This part belongs to the 24VL014H family of serial EEPROMs designed for low-voltage operations. It shares functional similarities with other I²C EEPROMs but is distinguished by its extended low-voltage capability starting at 1.5V. The device utilizes a single-block memory organization accessible through a standard two-wire serial interface.

Memory IC Replacement Considerations

Compatible substitutes within the same family include the 24LC014H and 24AA014H series. When replacing, verify that the alternative part supports the required 1.5V minimum operating voltage and matches the physical package footprint.
