24LC024-E/SN

Memory IC Overview

The Microchip Technology 24LC024-E/SN 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 a maximum clock frequency of 400 kHz via a 2-Wire I²C compatible interface. The device features an access time of 900 ns, a typical standby current of 1 μA, and a typical active read current of 1 mA. It is housed in an 8-lead SOIC package with a width of 3.90 mm and is rated for industrial temperature operation between -40°C and +125°C.

Memory IC Feature Summary

• Hardware write protection enabled by the WP pin
• Schmitt trigger inputs for noise suppression
• Output slope control to eliminate ground bounce
• Self-timed erase/write cycle with page write capability

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in industrial instrumentation
• Device identification and security code storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range requirements align with the 2.5V minimum specification for the LC series. Ensure the hardware write protect pin is properly configured in the design schematic to prevent unintended data modification during operation.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM capacity is required with I²C connectivity. The automotive temperature grade (-40°C to +125°C) makes it suitable for harsh environments. Consider the 16-byte page write buffer for efficient data writing operations. Verify that the system power supply remains above 2.5V to ensure proper functionality.

Memory IC Part Context

This part belongs to the 24AA024/24LC024 family of 2 Kbit serial EEPROMs. It shares functional similarities with the 24AA024 but differs in operating voltage range. The device is designed for low-power applications and offers high endurance with over one million erase/write cycles. It supports cascading up to eight devices on a single bus using hardware address pins.

Memory IC Replacement Considerations

The 24LC024-I/SN serves as a direct replacement for industrial temperature grades (-40°C to +85°C).
