24LC024-I/ST

Memory IC Overview

The Microchip Technology 24LC024-I/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 a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead TSSOP package and rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using hardware address pins A0, A1, and A2.
• Includes a hardware write-protect pin that enables or disables array writing based on logic level.
• Features output slope control to eliminate ground bounce and Schmitt trigger inputs for noise suppression.

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Device identification and calibration data retention

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' corresponds to the Industrial temperature grade (-40°C to +85°C) and the TSSOP-8 package type. Confirm the presence of the Write Protect (WP) pin functionality, as this distinguishes the 24LC024 variant from the 24LC025 which lacks this pin. Ensure compatibility with the system's I²C pull-up resistor requirements for the target clock speed.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is required with hardware-level write protection. It is suitable for designs needing up to eight devices on one bus. Consider the 24AA024 if operation below 2.5V is necessary, as the 24LC024 requires a minimum of 2.5V. Verify that the TSSOP-8 package fits the PCB footprint constraints.

Memory IC Part Context

This part belongs to the 24AA024/24LC024 family of 2 Kbit Serial Electrically Erasable PROMs. These devices are designed for low-power applications using CMOS technology. The family shares functional similarities but differs in voltage ranges and write protection availability, with the 24LC series supporting a 2.5V to 5.5V range.

Memory IC Replacement Considerations

The 24AA024 offers similar functionality but supports a lower voltage range of 1.7V to 5.5V. The 24LC025 provides identical electrical characteristics and package options but lacks the hardware write-protect pin.
