24VL014H/MS

Memory IC Overview

The Microchip Technology 24VL014H/MS is a 1 Kbit (128 x 8) serial Electrically Erasable PROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.5V to 3.6V, with a maximum clock frequency of 400 kHz at VCC ≥ 1.8V and 100 kHz below 1.8V. The device supports page writes of up to 16 bytes and includes hardware write protection for the upper half of the array via the WP pin. It provides over 1 million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.5V with minimal active and standby currents.
• Hardware write-protect capability that secures the upper half of the memory array against unauthorized modifications.
• Integrated Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce.
• Supports cascading up to eight devices on a single bus to expand contiguous address space.

Memory IC Applications

• Battery-powered portable electronics requiring low-voltage operation
• Industrial systems needing robust noise immunity on serial buses
• Embedded controllers storing configuration parameters or calibration data

Memory IC Procurement Notes

Verify the specific suffix 'MS' corresponds to the MSOP-8 package when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the operating environment stays within the specified -20°C to +85°C temperature range. Check for any recent Product Change Notifications regarding packaging or material updates.

Memory IC Selection Notes

Select this component for designs requiring ultra-low voltage operation starting at 1.5V. The MSOP package is suitable for space-constrained surface-mount applications. Consider the hardware write-protect feature if partial memory security is required without software overhead. Verify bus capacitance limits if connecting multiple devices to ensure signal integrity at 400 kHz.

Memory IC Part Context

This part belongs to the 24VL014H family of 1Kb I²C Serial EEPROMs. It shares functional similarities with other members like the 24LC014H but is distinguished by its extended low-voltage capability down to 1.5V. The MSOP variant offers a compact footprint compared to standard SOIC or PDIP packages.
