24LC01BT-E/SN

Memory IC Overview

The Microchip Technology 24LC01BT-E/SN is a 1 Kbit (128 x 8) serial EEPROM utilizing an I2C-compatible 2-wire interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features low-power CMOS technology with maximum standby current of 5 µA and read current of 1 mA. It includes an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead SOIC package and is 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 compatible serial bus protocol.
• Includes an 8-byte page write buffer to optimize write throughput and reduce internal programming cycles.
• Features hardware write protection that inhibits all memory writes when the WP pin is tied to VCC.
• Incorporates Schmitt trigger inputs and filter circuits on SDA and SCL lines to suppress noise spikes.

Memory IC Applications

• Non-volatile data storage for system configuration parameters
• Calibration value retention in measurement instruments
• Device identification and serial number storage
• Parameter logging in embedded control systems

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'SN' denotes the 8-lead SOIC package. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering code matches the required voltage and speed specifications for the target application environment.

Memory IC Selection Notes

Select this part for applications requiring non-volatile storage with minimal pin count and low power consumption. The 24LC01BT-E/SN is suitable where a 1 Kbit capacity suffices and operation at voltages down to 2.5V is required. Consider the 8-byte page buffer for efficient data writing. Verify that the I2C bus pull-up resistors are correctly sized for the 400 kHz operating frequency.

Memory IC Part Context

This component 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 minimum operating voltage and maximum clock frequency. The 24LC01B series specifically targets applications requiring operation down to 2.5V with 400 kHz I2C compatibility.
