24VL014T/ST

Memory IC Overview

The Microchip Technology 24VL014T/ST is a 1 Kbit (128 x 8) serial EEPROM 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. The device utilizes low-power CMOS technology, drawing a maximum active current of 400 μA and standby current of 1 μA. It includes hardware write protection for the entire array via the WP pin, supports page writes up to 16 bytes, and offers over one million erase/write cycles with data retention exceeding 200 years.

Memory IC Feature Summary

• Low-voltage operation down to 1.5V with minimal power consumption
• Hardware write protection capability for the complete memory array
• Integrated Schmitt trigger inputs for enhanced noise suppression
• Supports cascading up to eight devices on a single bus

Memory IC Applications

• Battery-powered portable electronic devices requiring low standby current
• Industrial control systems needing reliable non-volatile data storage
• Smart metering applications utilizing hardware write protection
• Embedded systems managing configuration parameters via I²C

Memory IC Procurement Notes

Verify that the ordering suffix 'ST' corresponds to the TSSOP package type as specified in the manufacturer's documentation. Confirm the specific temperature grade and RoHS compliance status required for your assembly process. Ensure the component matches the exact part number format to guarantee compatibility with existing design files and BOMs.

Memory IC Selection Notes

Select this component when a small footprint and low operating voltage are critical requirements. The TSSOP package provides a compact solution for space-constrained designs. Consider the hardware write protection feature if system security against accidental overwrites is necessary. Verify that the I²C bus speed requirements align with the device's 400 kHz maximum clock frequency.

Memory IC Part Context

This component belongs to the 24VL014 family of serial EEPROMs designed for low-voltage applications. The family shares common electrical characteristics and interface protocols but differs in packaging options such as PDIP, SOIC, MSOP, and TDFN. The 'T' suffix typically indicates tape and reel packaging, while 'ST' specifies the TSSOP package variant within this series.

Memory IC Replacement Considerations

Compatible substitutes include other 24VL014 variants with different packages, such as 24VL014/SN or 24VL014/MS. Cross-referencing with the 24LC014 series may be possible if voltage levels and timing parameters are compatible, though direct replacement requires verifying package dimensions and pinout alignment.
