24LC024H-I/P

Memory IC Overview

The Microchip 24LC024H-I/P is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports I²C™ compatible 2-wire serial interfaces with maximum clock frequencies of 100 kHz or 400 kHz. The device features hardware write protection for the upper half of the array, low-power CMOS technology with active current up to 400 μA and standby current up to 1 μA, and an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Low-power CMOS design ensures minimal active and standby current consumption for energy-efficient operation.
• I²C™ compatible 2-wire serial interface allows connection of up to eight devices on a single bus using configurable address lines.

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in battery-powered devices

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'P' indicates the 8-pin PDIP package. Confirm the specific voltage range requirements align with the 2.5V to 5.5V specification for the LC variant. Ensure compatibility with the host system's I2C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution is required with hardware-level write protection capabilities. The Industrial temperature rating makes it suitable for environments exceeding standard commercial limits. Consider the PDIP package only if through-hole mounting is necessary for the target application.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit Serial EEPROMs. The 'LC' designation distinguishes it from the 'AA' series by supporting higher clock speeds up to 1 MHz and operating at a minimum voltage of 2.5 V rather than 1.7 V. The 'I' suffix denotes the industrial temperature grade.

Memory IC Replacement Considerations

The 24LC024T-I/SNG serves as a surface-mount alternative within the same functional family, offering identical electrical characteristics in an SOIC package.

Memory IC FAQ

How does the hardware write protection function?

Connecting the WP pin to VCC enables hardware write protection, preventing writes to the upper half of the array (addresses 80h-FFh).

What is the maximum clock frequency supported?

The 24LC024H supports clock frequencies up to 1 MHz, provided the supply voltage is between 2.5 V and 5.5 V.
