24LC014HT-I/ST

Memory IC Overview

The Microchip Technology 24LC014HT-I/ST is a 1 Kbit (128 x 8) serial EEPROM featuring an I²C interface. It operates within a voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 1 MHz. The device utilizes TSSOP-8 packaging and functions across an industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum active read current of 3 mA, a standby current of 1 μA, and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Page write buffer supporting up to 16 bytes per cycle
• Schmitt trigger inputs with noise suppression on SDA and SCL lines
• Internal address pointer enabling sequential read operations

Memory IC Applications

• Industrial control systems requiring non-volatile parameter storage
• Embedded devices needing configuration data retention
• Low-power battery-operated equipment utilizing I²C communication

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range aligns with system requirements, as the 'LC' variant specifies a minimum of 2.5 V. Ensure compatibility with the host controller's I²C bus speed limits before finalizing procurement.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application needs. The 1 MHz clock rate offers higher throughput compared to standard 400 kHz variants. Consider the TSSOP-8 package dimensions for PCB layout constraints. Verify that the hardware write protection feature meets security requirements for critical data segments.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial Electrically Erasable PROMs. The 'LC' designation indicates operation down to 2.5 V with support for 1 MHz clock speeds. The 'I' suffix denotes the Industrial temperature grade. The 'HT' suffix typically signifies tape and reel packaging for automated assembly.
