24LC08BT-E/MC

Memory IC Overview

The Microchip Technology 24LC08BT-E/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. The device operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz at these voltages, dropping to 100 kHz below 2.5V. It utilizes low-power CMOS technology with a maximum active read current of 1 mA and standby current of 5 µA in extended temperature conditions. The component is housed in an 8-lead DFN package and is rated for industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard two-wire serial bus protocol.
• Includes hardware write protection controlled by the WP pin to inhibit write operations.
• Features Schmitt trigger inputs and noise suppression filters on SDA and SCL lines.
• Provides page write capability with a 16-byte buffer to enhance bus throughput.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and package type. Confirm the voltage operating range matches the system design, as this variant requires a minimum of 2.5V. Ensure compatibility with the host controller's I2C pull-up resistor values for reliable signaling at the target clock speed.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is needed for small capacity non-volatile memory requirements. It is suitable for designs where power consumption during standby is critical but operation below 2.5V is not required. Consider the 8-lead DFN package for space-constrained PCB layouts compared to larger SOIC or DIP options.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs, which shares architectural similarities with the 24AA08 and 24FC08 series. While functionally similar regarding memory organization and interface, differences exist in minimum operating voltage and maximum clock frequency across the family variants.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages such as 24LC08BT-I/MS or 24LC08BT-E/MNY, provided the temperature rating and physical footprint are acceptable for the application.
