24VL014H/P

Memory IC Overview

The Microchip Technology 24VL014H/P is a 1 Kbit (128 x 8) serial EEPROM featuring a 2-wire I²C interface. It operates within a supply voltage range of 1.5V to 3.6V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology with maximum active current of 400 μA and standby current of 1 μA. It includes hardware write protection for half the array, a page write buffer for up to 16 bytes, and Schmitt trigger inputs for noise suppression. Available in an 8-pin PDIP package, it functions between -20°C and +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Integrated Schmitt triggers and output slope control provide enhanced noise immunity and eliminate ground bounce.
• Supports cascading up to eight devices on a single bus using configurable chip select address lines.

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• I²C bus sensor configuration and calibration data retention
• Industrial control applications operating in electrically noisy environments

Memory IC Procurement Notes

Verify that the ordering suffix 'P' corresponds specifically to the 8-pin PDIP package type. Confirm the RoHS compliance status matches project requirements. Ensure the selected component meets the specified ambient temperature range of -20°C to +85°C for the intended operational environment.

Memory IC Selection Notes

Select this part when operation down to 1.5V is required compared to standard 2.7V EEPROMs. Choose the PDIP variant if through-hole mounting is necessary for mechanical stability or prototyping. Consider the 400 kHz speed limit and ensure the system bus timing accommodates the specific rise/fall time constraints at lower voltages.

Memory IC Part Context

This component belongs to the 24VL014 family of serial EEPROMs designed for ultra-low voltage applications. Unlike higher voltage variants, this series supports operation starting at 1.5V, making it suitable for battery-powered devices. The 'H' designation indicates the specific memory organization and feature set compatible with standard I²C protocols.

Memory IC Replacement Considerations

Microchip 24LC014H/P: Requires 2.5V minimum supply voltage and offers 1 MHz clock speed.

Memory IC FAQ

How does the hardware write protection function?

Tying the WP pin to VCC enables hardware write protection for the upper half of the array (addresses 40h-7Fh). Writes to this protected region are ignored by the device.

What is the behavior during a page write across a boundary?

If a page write attempts to cross a physical page boundary, the data wraps around to the beginning of the current page rather than proceeding to the next page.
