24LC024-E/ST

Memory IC Overview

The Microchip Technology 24LC024-E/ST is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features hardware write protection via the WP pin, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead TSSOP package and rated for industrial automotive temperature ranges of -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection enabled by tying the WP pin to VCC
• 16-byte page write buffer for efficient data storage operations
• Schmitt trigger inputs with spike suppression for reliable bus communication

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in automotive electronic modules

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm the presence of the Write Protect pin functionality if hardware security is necessary for the design. Ensure compatibility with the system's I²C bus voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires hardware-level write protection and high endurance. It is suitable for applications needing low standby current and robust noise immunity in electrically noisy environments. Consider the 16-byte page buffer size when optimizing software write algorithms for throughput.

Memory IC Part Context

This part belongs to the 24AA024/24LC024 family of 2 Kbit serial EEPROMs. It shares functional similarities with the 24LC025 but differs in capacity and write protection availability. The 'E' designation indicates an extended temperature range capability compared to standard industrial grades.

Memory IC Replacement Considerations

Direct substitutes include other 24LC024 variants with different packages such as SOIC or DFN. Cross-reference with 24AA024 devices if lower voltage operation down to 1.7V is required, noting differences in operating voltage specifications.
