24LC024T-E/ST

Memory IC Overview

The Microchip Technology 24LC024T-E/ST is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible 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 includes hardware write protection via the WP pin, utilizes a 16-byte page write buffer, and offers data retention exceeding 200 years with over one million erase/write cycles. It is housed in an 8-lead TSSOP package.

Memory IC Feature Summary

• Hardware write protection enabled by tying the WP pin high
• 16-byte page write buffer for efficient data transfer
• Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Memory IC Procurement Notes

Verify that the 'E' suffix confirms the Automotive temperature grade (-40°C to +125°C). Confirm the '/ST' suffix corresponds to the TSSOP-8 package. Ensure the specific revision of DS21210N matches the required electrical characteristics for your operating voltage range.

Memory IC Selection Notes

Select this part when hardware write protection is mandatory for the application. The 24LC024 series requires a minimum supply voltage of 2.5V, unlike the 24AA024 which supports 1.7V. Verify that the 400 kHz bus speed meets the system timing requirements.

Memory IC Part Context

This component belongs to the 24LC024 family of 2-Kbit serial EEPROMs. It shares functional similarities with the 24LC025 but differs in having a dedicated hardware write-protect pin. The 'E' designation indicates an extended automotive temperature range compared to the standard Industrial grade.

Memory IC Replacement Considerations

The 24LC024T-I/ST serves as the Industrial temperature grade equivalent. The 24AA024T-E/ST provides similar functionality but supports lower voltages down to 1.7V.
