24LC16B-M/SN

Memory IC Overview

The Microchip Technology 24LC16B-M/SN is a 16 Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a 2-wire serial interface compatible with I²C protocols, supporting maximum clock frequencies up to 400 kHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and utilizes low-power CMOS technology. It is housed in an 8-lead Plastic SOIC package with a body width of 3.90 mm. The component supports hardware write protection via the WP pin and includes Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication using standard I²C protocols
• Includes hardware write protection controlled by the dedicated WP pin
• Features internal self-timed erase/write cycles with automatic page buffering
• Provides high ESD protection ratings exceeding 4,000V across all pins

Memory IC Applications

• Industrial control systems requiring extended temperature operation
• Embedded devices needing non-volatile data storage for configuration parameters
• Automotive electronics demanding reliability under harsh environmental conditions

Memory IC Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'M' designation indicates an extended temperature range of -55°C to +125°C. Confirm the '/SN' suffix corresponds to the 8-lead SOIC package type. Ensure compatibility with system voltage levels between 2.5V and 5.5V before integration.

Memory IC Selection Notes

Select this component when applications require robust performance across extreme temperatures beyond standard industrial limits. The 8-pin SOIC package facilitates surface mount assembly. Consider the 16-byte page write buffer for efficient data throughput. Verify that the I²C bus speed requirements do not exceed the specified 400 kHz limit.

Memory IC Part Context

This part belongs to the 24LC16B family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members of the series but is distinguished by its specific temperature rating and physical packaging. The device is designed for applications where data retention and endurance are critical factors.

Memory IC Replacement Considerations

Direct substitutes include other 24LC16B variants with different temperature or package codes, such as 24LC16B-I/SN for industrial ranges. Cross-brand replacements must match the 16 Kbit capacity, I²C interface, and voltage specifications.
