24LC014H-I/ST

Memory IC Overview

The Microchip Technology 24LC014H-I/ST is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring a 2-wire I²C compatible interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 1 MHz in the Industrial temperature grade (-40°C to +85°C). 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 16-byte page write buffer, and offers data retention exceeding 200 years with 1 million erase/write cycles endurance.

Memory IC Feature Summary

• Supports high-speed 1 MHz I²C communication alongside standard 100 kHz and 400 kHz modes
• Provides hardware write protection for the upper half of the memory array via the WP pin
• Features Schmitt trigger inputs and output slope control for enhanced noise suppression and ground bounce elimination

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded applications needing configuration parameter retention
• Multi-device bus architectures utilizing chip select addressing

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the TSSOP-8 package type as indicated by the ST designation. Confirm the 'I' suffix matches the required industrial temperature range specifications. Ensure compatibility with the system's I²C bus voltage levels and check for any specific RoHS compliance documentation requirements relevant to the manufacturing batch.

Memory IC Selection Notes

Select this component when a 1 MHz I²C interface speed is required compared to the standard 400 kHz limit found in other variants like the 24LC014. Consider the hardware write protection feature if partial array security is necessary. Verify that the 2.5V minimum operating voltage aligns with the target system power supply constraints.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial EEPROMs. It shares architectural similarities with the 24LC014 but distinguishes itself through an increased maximum clock frequency capability. The family supports multiple package options including SOIC, TSSOP, MSOP, and TDFN, allowing flexibility in PCB layout design.

Memory IC Replacement Considerations

The 24LC014 serves as a direct functional substitute with identical organization but limited to 400 kHz operation. The 24AA014H offers similar features but supports a lower voltage range starting at 1.7V.
