24LC01BT-E/MC

Memory IC Overview

The Microchip Technology 24LC01BT-E/MC is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, ensuring standby currents are minimized. It includes an 8-byte page write buffer and hardware write-protect capabilities via the WP pin. The component is housed in an 8-lead DFN package and is rated for extended temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transfer using a standard 2-wire serial bus protocol compatible with I2C.
• Includes Schmitt trigger inputs on SCL and SDA lines to suppress noise spikes and ensure stable operation.
• Features hardware write protection controlled by the WP pin to inhibit memory writes when tied high.
• Provides output slope control designed to eliminate ground bounce during switching operations.

Memory IC Applications

• Non-volatile data storage for system configuration parameters
• Calibration value retention in industrial instrumentation
• Device identification and tracking information logging

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the specific Extended temperature grade (-40°C to +125°C) and the 8-lead DFN package format. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding marking or packaging updates before finalizing procurement specifications.

Memory IC Selection Notes

Select this part when a 1 Kbit capacity is required with I2C connectivity and extended temperature tolerance. Ensure the application voltage remains above 2.5V, as lower voltages restrict the maximum clock frequency. Compare against the 24AA01 variant if operation below 2.5V is necessary, noting the difference in minimum supply requirements.

Memory IC Part Context

This component belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common functional architectures but differs in voltage ranges and speed ratings. The 24LC01B specifically targets applications requiring reliable non-volatile storage at standard logic levels without the ultra-low voltage capability of the 24AA01 series.
