24LC08BT-E/OT16KVAO

Memory IC Overview

The Microchip Technology 24LC08BT-E/OT is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and features a 2-Wire Serial Interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, ensuring standby currents are minimized. It is housed in a 5-lead SOT-23 surface-mount package and is qualified for extended temperature ranges from -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial interface compatible with I2C protocols.
• Includes hardware write-protect functionality controlled by the WP pin to inhibit write operations when tied to VCC.
• Features Schmitt trigger inputs and filter circuits on SDA and SCL pins to suppress noise spikes.
• Provides output slope control designed to eliminate ground bounce during signal transitions.

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability.
• Configuration storage for embedded systems utilizing I2C communication.
• Parameter retention in automotive electronics meeting AEC-Q100 standards.
• Calibration data storage for sensor modules operating within specified voltage ranges.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm that the application circuit provides adequate pull-up resistors for the I2C bus lines. Ensure power supply voltages remain within the specified 2.5V to 5.5V range to prevent operational faults. Check for moisture sensitivity handling requirements if the component has been stored for extended periods.

Memory IC Selection Notes

Select this component when an 8-Kbit non-volatile memory solution is needed with I2C compatibility. The extended temperature rating makes it suitable for harsh environments where standard industrial grades may fail. Consider the SOT-23 package for space-constrained designs requiring surface mount assembly. Verify that the system voltage does not drop below 2.5V, as lower voltages are not supported by this specific variant.

Memory IC Part Context

This part belongs to the 24LC08B series of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 devices but differs in minimum operating voltage and maximum clock frequency specifications. The series is designed for applications requiring reliable data retention and low power consumption in compact form factors.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC08BT-I/OT for industrial temperature range variants and 24LC08BT/SN for alternative SOIC packaging options. Cross-reference datasheet electrical characteristics to ensure voltage and timing compatibility before substitution.
