24LC024/P

Memory IC Overview

The Microchip Technology 24LC024/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 2.5V to 5.5V and utilizes a 2-wire I²C compatible serial interface with a maximum clock frequency of 400 kHz. The device features hardware write protection via the WP pin, supports page writes up to 16 bytes, and offers data retention exceeding 200 years with over one million erase/write cycles endurance.

Memory IC Feature Summary

• Hardware write-protect capability enabled by tying the WP pin to VCC
• I²C compatible bidirectional serial bus supporting cascading of up to eight devices
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Industrial controllers requiring non-volatile parameter storage
• Low-power sensor nodes utilizing I²C communication
• Embedded systems needing hardware-level data protection

Memory IC Procurement Notes

Verify that the ordering suffix '/P' corresponds specifically to the 8-lead PDIP package type. Confirm the voltage range requirement matches the 2.5V to 5.5V specification for the 24LC024 series, distinct from the 1.7V capable 24AA024. Ensure the application requires the hardware write-protect feature available on this specific model.

Memory IC Selection Notes

Select this component when an industrial temperature range (-40°C to +85°C) and through-hole mounting are required. The 24LC024/P provides hardware write protection, unlike the 24LC025 variant. It is suitable for designs operating strictly above 2.5V, whereas applications requiring operation below 2.5V must utilize the 24AA024 series.

Memory IC Part Context

This part belongs to the 24AA024/24LC024 family of 2Kb serial EEPROMs manufactured by Microchip Technology. The 'P' suffix designates the 8-lead Plastic Dual In-Line Package (PDIP). It shares functional similarities with the SOIC, TSSOP, and MSOP variants within the same electrical specification sheet.

Memory IC Replacement Considerations

Public confirmed substitute part numbers: 24LC024/I/SN, 24LC024-I/MS, 24LC024-E/MC.
