24LC01BT/OT

Memory IC Overview

The Microchip Technology 24LC01BT/OT is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in a 5-lead SOT-23 package. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via an I²C compatible 2-wire serial interface. The device features industrial temperature range operation from -40°C to +85°C, with a typical access time of 3.5 µs and a maximum page write cycle time of 5 ms.

Memory IC Feature Summary

• Supports bidirectional data transmission using a standard 2-wire serial bus protocol.
• Includes hardware write protection controlled by the WP pin to inhibit memory writes.
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination.

Memory IC Applications

• Non-volatile data storage in low-power embedded systems
• Configuration parameter retention in consumer electronics
• Device identification and calibration data logging

Memory IC Procurement Notes

Verify that the ordering suffix /OT corresponds specifically to the SOT-23-5 package variant. Confirm the 'I' designation indicates the Industrial temperature range (-40°C to +85°C). Ensure the supply voltage requirements align with the 2.5V minimum specification for the 24LC01B series before integration.

Memory IC Selection Notes

Select this component when a compact surface-mount footprint is required alongside I²C connectivity. The SOT-23-5 package offers space efficiency compared to 8-lead options. Consider the 400 kHz speed limit and 2.5V minimum operating voltage when designing power rails and bus timing constraints.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA01 and 24FC01, which differ primarily in operating voltage ranges and maximum clock frequencies. The 24LC01B specifically targets applications requiring a 2.5V to 5.5V supply range.

Memory IC Replacement Considerations

Direct replacements within the same package include other 24LC01B variants such as 24LC01BT-I/LT (SC-70-5), though pinouts may differ slightly. Cross-family substitutes like 24AA01 or 24FC01 require verification of voltage compatibility and clock speed limits.
