24LC01BT/ST

Memory IC Overview

The Microchip Technology 24LC01BT-I/ST is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-Wire I2C compatible serial interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology with a maximum active read current of 3 mA and standby current of 5 µA at extended temperatures. It includes an 8-byte page write buffer, hardware write-protect functionality via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-Lead TSSOP package and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission using I2C compatible protocol with start and stop conditions.
• Features hardware write protection that inhibits all memory writes when the WP pin is tied to VCC.
• Includes internal address pointer for sequential reading and automatic incrementing after each byte access.
• Provides acknowledge polling capability to determine when internal write cycles are complete.

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in consumer electronics

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range requirements align with the 2.5V minimum specification for the 24LC01B series. Ensure design compatibility with I2C bus timing constraints and pull-up resistor values. Check for RoHS compliance status if required by regulatory standards.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with minimal pin count and standard I2C connectivity. Consider the 8-byte page write buffer for efficient data writing operations. Evaluate the operating voltage range against system power rails. Verify thermal performance requirements against the specified industrial temperature limits.

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 24AA01 and 24FC01 with different voltage and speed characteristics. The 24LC01B specifically targets applications requiring operation down to 2.5V. The 'I' designation indicates industrial temperature rating, while 'ST' denotes the TSSOP package.

Memory IC Replacement Considerations

Direct substitutes include other 24LC01B variants with different packages such as 24LC01B-I/SN or 24LC01B-I/P. Cross-family replacements like 24AA01 offer lower voltage operation but may require voltage level adjustments. Ensure pinout compatibility and electrical specifications match before substitution.
