24LC08BT/SN

Memory IC Overview

The Microchip Technology 24LC08BT/SN is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting a maximum clock frequency of 400 kHz for supply voltages between 2.5V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports page write operations with a 16-byte buffer to enhance bus throughput efficiency.
• Includes hardware write protection via the WP pin to inhibit write cycles when tied to VCC.
• Features Schmitt trigger inputs and noise suppression filters on SDA and SCL lines for reliable operation in noisy environments.

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration parameter storage in embedded systems
• Calibration data retention for sensor modules

Memory IC Procurement Notes

Verify the specific suffix 'BT' against the manufacturer's current datasheet to confirm if it denotes a tape-and-reel packaging variant or a specific temperature grade extension. Ensure the ordering code matches the required 8-SOIC package dimensions and lead finish specifications defined in the official Microchip packaging guide.

Memory IC Selection Notes

Select this component for designs requiring low-power I2C EEPROM with hardware write protection. Confirm that the system voltage remains above 2.5V to ensure the specified 400 kHz clock speed is maintained. Verify that the 8-SOIC footprint aligns with the PCB layout constraints and thermal requirements of the target application environment.

Memory IC Part Context

This part belongs to the 24LC08B series, which shares architectural similarities with the 24AA08 and 24FC08 devices. While the 24AA08 supports lower voltages down to 1.7V and the 24FC08 offers higher speeds up to 1 MHz, the 24LC08B is optimized for standard 2.5V to 5.5V operation with 400 kHz compatibility.

Memory IC Replacement Considerations

Direct functional substitutes include the 24LC08B-I/SN for industrial temperature grades and the 24LC08B-E/SN for extended temperature ranges. Other packages such as MSOP or TSSOP are available under different suffixes like /MS or /ST.
