24LC16B-E/MS

Memory IC Overview

The Microchip Technology 24LC16B-E/MS is a 16-Kbit (2K x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz at VCC ≥ 2.5V, or 100 kHz below 2.5V. The device is organized into eight blocks of 256 bytes with a 16-byte page write buffer. It offers extended temperature operation from -40°C to +125°C, hardware write protection via the WP pin, and over 1 million erase/write cycles.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Includes hardware write-protect functionality controlled by the WP pin state
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Provides self-timed erase/write cycles with automatic acknowledgment polling capability

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control units needing reliable memory in high-temperature environments
• Consumer electronics utilizing low-power serial interfaces for device identification
• Automotive modules requiring AEC-Q100 qualified components for safety-critical logging

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the Extended temperature rating (-40°C to +125°C) aligns with system thermal constraints. Ensure supply chain sources provide authentic Microchip Technology products to guarantee reliability and compliance with RoHS standards.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is sufficient for application requirements. Choose the MSOP package for space-constrained surface-mount designs. Ensure the system voltage remains above 2.5V to utilize the full 400 kHz clock speed. Verify that the I²C bus pull-up resistors are correctly sized for the desired operating frequency.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which also includes the 24AA16 and 24FC16 variants. While sharing the same memory architecture and interface, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24LC16B specifically targets applications requiring stable operation starting at 2.5V.

Memory IC Replacement Considerations

Direct functional substitutes include other 24LC16B variants with different packages such as 24LC16B-I/SN or 24LC16B-E/MC. Cross-family replacements like 24AA16 or 24FC16 require verification of voltage level compatibility and clock speed limitations before integration.
