24LC08BT-I/MC

Memory IC Overview

The Microchip Technology 24LC08BT-I/MC 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 clock frequencies up to 400 kHz at supply voltages between 2.5V and 5.5V. The device utilizes low-power CMOS technology, ensuring standby currents of 1 µA maximum and read currents of 1 mA maximum. It includes a 16-byte page write buffer and hardware write-protect capabilities via the WP pin. The component operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-lead DFN package.

Memory IC Feature Summary

• Supports bidirectional data transmission over a two-wire serial bus with Schmitt trigger inputs for noise suppression.
• Includes a 16-byte page write buffer to facilitate efficient sequential data writing operations.
• Provides hardware write protection through the WP pin to prevent unintended memory modifications.
• Features output slope control designed to eliminate ground bounce during signal transitions.

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings or event timestamps.
• Configuration storage for microcontrollers and embedded systems managing system parameters.
• Calibration data retention in industrial instrumentation and measurement devices.
• Identification and tracking information storage in consumer electronics and smart appliances.

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type, as variations exist within the 24LC08B family. Confirm compatibility with the target I²C bus voltage levels, noting that this model requires a minimum supply voltage of 2.5V. Ensure design adherence to the specified electrical characteristics for reliable operation across the intended industrial temperature range.

Memory IC Selection Notes

Select this component when an 8-Kbit capacity is sufficient for application requirements and a compact surface-mount footprint is necessary. The 24LC08BT-I/MC is suitable for designs operating strictly within the 2.5V to 5.5V supply range. Consider alternative models like the 24AA08 if lower voltage operation down to 1.7V is required, or the 24FC08 if higher speed interfaces are needed.

Memory IC Part Context

This part belongs to the 24XX08 series of serial EEPROMs from Microchip Technology, which also includes the 24AA08 and 24FC08 variants. These devices share similar architectural features but differ in operating voltage ranges and maximum clock frequencies. The 24LC08B specifically targets applications requiring standard I²C compatibility with a 2.5V minimum supply voltage, distinguishing it from the wider voltage range of the 24AA08.

Memory IC Replacement Considerations

Direct substitutes include other packages within the same 24LC08B family, such as 24LC08BT-I/MS or 24LC08B-I/MC, provided the pinout and electrical specifications remain identical. Cross-family replacements like the 24AA08 require verification of voltage level compatibility.
