24LC08BT-I/OT

Memory IC Overview

The Microchip Technology 24LC08BT-I/OT is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V and features a two-wire serial interface compatible with I²C protocols, supporting clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, ensuring maximum read current of 1 mA and standby current of 1 µA at industrial temperatures. It includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. The component is rated for industrial temperature ranges from -40°C to +85°C and is housed in a 5-lead SOT-23 package.

Memory IC Feature Summary

• Supports bidirectional data transmission over a two-wire serial bus with I²C compatibility
• Includes a 16-byte page write buffer to optimize write operations
• Features hardware write protection controlled by the WP pin state
• Incorporates Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Data storage in embedded systems requiring non-volatile memory
• Configuration parameter retention in consumer electronics
• Device identification and calibration data logging in industrial controllers

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOT-23-5 package type and Industrial temperature grade (-40°C to +85°C). Confirm that the voltage range requirement aligns with the 2.5V minimum specification for the 24LC08B series, distinct from the 1.7V capable 24AA08 or 24FC08 variants. Ensure the application design accounts for the hardware write-protect functionality if data security is required.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is needed for small-scale non-volatile data storage. The 5-lead SOT-23 package offers space efficiency compared to 8-lead options. Designers must ensure the system voltage does not drop below 2.5V during operation, as lower voltages are not supported by this specific part number variant. Consider the 16-byte page buffer size when designing write algorithms to maximize throughput.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA08 and 24FC08 but differs in operating voltage and speed specifications. The 24LC08B series specifically targets applications requiring reliable operation between 2.5V and 5.5V without the extended speed or ultra-low voltage capabilities of its siblings.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC08BT-E/OT for extended temperature operation.
