24LC01BT-E/OT16KVAO

Memory IC Overview

The Microchip Technology 24LC01BT-E/OT is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) utilizing a 2-Wire I²C compatible serial interface. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 400 kHz. The device features an access time of 900 ns, a page write buffer for up to 8 bytes, and hardware write protection via the WP pin. It is housed in a 5-lead SOT-23 package and rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard 2-wire I²C serial bus protocol with Schmitt trigger inputs for noise suppression.
• Includes an 8-byte page write buffer to enhance throughput during sequential data writes.
• Provides hardware-based write protection for the entire memory array when the WP pin is tied to VCC.
• Features output slope control designed to eliminate ground bounce effects during switching.

Memory IC Applications

• Data logging and storage in battery-powered portable devices
• Configuration parameter storage in embedded systems
• Calibration data retention in industrial instrumentation

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm the voltage range requirements align with the 2.5V minimum specification for the LC series. Ensure the design accounts for the SOT-23-5 footprint dimensions and thermal characteristics appropriate for the extended temperature rating.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with low active current consumption. The extended temperature range makes it suitable for harsh environments where standard industrial parts may fail. Consider the page write capability if high-speed sequential writing is necessary compared to byte-write operations.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The 'E' designation indicates an extended temperature range (-40°C to +125°C), while 'I' denotes industrial range. The 'OT' suffix specifies the 5-lead SOT-23 surface-mount package. Other family members include the 24AA01 and 24FC01 with different voltage or speed specifications.

Memory IC Replacement Considerations

Direct replacements within the same package and electrical specifications include the 24LC01BT-I/OT for industrial temperature grades. Cross-family alternatives like the 24AA01 offer lower voltage operation but require verification of interface compatibility and physical pinout alignment.
