24LC01B-I/SN

Memory IC Overview

The Microchip Technology 24LC01B-I/SN is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead SOIC 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 a 2-wire I²C compatible serial interface. The device features Schmitt trigger inputs for noise suppression, hardware write protection, and output slope control to eliminate ground bounce. It is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication with up to 400 kHz clock frequency
• Includes an 8-byte page write buffer for efficient data transfer
• Features hardware write protection controlled by the WP pin
• Provides high ESD protection exceeding 4,000V

Memory IC Applications

• Microcontroller external memory expansion
• Storage of configuration parameters and system settings
• Recording system status logs

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) and 'SN' specifies the 8-lead SOIC package. Confirm the voltage range requirement matches the 2.5V minimum specification for the 24LC01B series, distinct from lower-voltage variants like the 24AA01.

Memory IC Selection Notes

Select this component when a 1 Kbit non-volatile storage solution is required with standard I²C connectivity. Ensure the application voltage does not drop below 2.5V, as this model differs from the 1.7V capable 24AA01. Consider the 8-byte page write capability for optimizing bus throughput during data logging tasks.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA01 and 24FC01 but is distinguished by its specific 2.5V to 5.5V operating voltage range and 400 kHz maximum clock speed compatibility.

Memory IC Replacement Considerations

The 24LC01BT-I/SN serves as a tape-and-reel replacement for bulk packaging needs. Other package variations within the same electrical specifications include 24LC01B-I/ST (TSSOP) and 24LC01B-I/P (PDIP).

Memory IC FAQ

How does the Write-Protect (WP) pin function?

Connecting the WP pin to VCC inhibits all write operations, protecting the entire memory array. Connecting it to VSS enables normal read and write access.

What is the behavior of pins A0, A1, and A2?

These pins are not internally connected for the 24LC01B device. They may be left floating or tied to either VSS or VCC without affecting operation.
