24VL014H/ST

Memory IC Overview

The Microchip Technology 24VL014H/ST is a 1 Kbit (128 x 8) serial EEPROM featuring a 2-wire I²C compatible interface. It operates on a single supply voltage ranging from 1.5V to 3.6V with a maximum clock frequency of 400 kHz. The device supports page write buffers for up to 16 bytes and includes hardware write protection for the upper half of the memory array via the WP pin. It is housed in an 8-lead TSSOP package and functions within an ambient temperature range of -20°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.5V with minimal active and standby currents.
• Hardware write protection capability that secures the upper half of the memory array when the WP pin is tied high.
• 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 using configurable chip select address lines.

Memory IC Applications

• Battery-powered embedded systems requiring low standby current
• Industrial controllers utilizing I²C communication protocols
• Consumer electronics needing non-volatile data storage for configuration parameters

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple form factors. Confirm the temperature grade aligns with the application environment, noting the industrial range specifications. Ensure the voltage supply meets the minimum operational threshold of 1.5V for reliable functionality across all specified conditions.

Memory IC Selection Notes

Select this component for designs requiring robust noise immunity through Schmitt trigger inputs and precise write protection for critical data segments. The device is suitable for applications demanding high endurance and long-term data retention without complex power management circuits. Consider the physical layout constraints associated with the TSSOP package dimensions during PCB design.

Memory IC Part Context

This component belongs to the 24VL014H family of serial EEPROMs designed for low-voltage microcontroller systems. It provides a cost-effective solution for storing calibration data or user settings in space-constrained environments. The series emphasizes reliability through advanced CMOS processes and comprehensive protection features against electrical overstress.

Memory IC Replacement Considerations

Direct replacements include other 1Kbit I²C EEPROMs from the same manufacturer family, such as the 24LC014 or 24AA014 variants, provided they support the required voltage range and package style. Verify pin compatibility and software register mappings before substituting.
