24VL014HT/SN

Memory IC Overview

The Microchip Technology 24VL014HT/SN is a 1 Kbit (128 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 interface communication with a maximum clock frequency of 400 kHz. The device features hardware write protection for half the array, low-power CMOS technology, and an operating temperature range of -20°C to +85°C.

Memory IC Feature Summary

• Supports operation down to 1.5V with low standby and active current consumption.
• Includes Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination.
• Features hardware write protection that secures the upper half of the memory array.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• I²C bus networks with multiple slave devices
• Battery-powered applications due to ultra-low power characteristics

Memory IC Procurement Notes

Verify the specific suffix 'HT' against official documentation to confirm tape-and-reel packaging status and any distinct manufacturing lot requirements. Ensure the SOIC-8 package variant matches the design footprint. Confirm RoHS compliance and lead-free specifications align with project constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when system power rails drop below 2.5V, as standard EEPROMs may fail. The 400 kHz clock rate suits moderate-speed data logging. Verify that the half-array write protection meets security needs; if full protection is required, software management must be implemented for the unprotected lower half.

Memory IC Part Context

This part belongs to the 24VL014H family of 1 Kbit serial EEPROMs designed for low-voltage environments. It shares architectural similarities with other I²C EEPROMs but is distinguished by its 1.5V minimum operating voltage and specific industrial-grade thermal handling within the specified ambient temperature range.

Memory IC Replacement Considerations

Direct substitutes include the 24LC014H series, though these typically require a higher minimum voltage of 2.5V. Ensure any replacement maintains compatibility with the 1.5V to 3.6V supply range and SOIC-8 pinout if voltage levels differ significantly.

Memory IC FAQ

How does the WP pin function?

Tying the WP pin to VCC enables hardware write protection for the upper half of the array (addresses 40h-7Fh), preventing writes to those locations. Tying it to VSS disables this protection.

What is the page write buffer size?

The device supports a page write buffer capable of storing up to 16 bytes of data before initiating an internal write cycle upon receiving a Stop condition.
