24LC16B-E/ST

Memory IC Overview

The Microchip Technology 24LC16B-E/ST is a 16-Kbit (2K x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device supports self-timed erase/write cycles with a page write buffer for up to 16 bytes, achieving a maximum write cycle time of 5 ms. It offers high endurance exceeding one million erase/write cycles and data retention greater than 200 years. The component is housed in an 8-lead TSSOP package and is rated for extended industrial temperature operation from -40°C to +125°C.

Memory IC Feature Summary

• Features hardware write protection via the WP pin to inhibit write operations when tied to VCC.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Supports acknowledge polling to determine internal write cycle completion and maximize bus throughput.
• Provides ESD protection exceeding 4,000V across all pins.

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices operating in extended temperature environments
• Consumer electronics utilizing I²C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'ST' specifies the TSSOP-8 package. Confirm the minimum operating voltage requirement of 2.5V aligns with the target system power supply, as this variant does not support operation below 2.5V unlike other members of the 24XX16 family.

Memory IC Selection Notes

Select this part for applications requiring robust data retention and high endurance within a compact surface-mount footprint. Ensure the design accommodates the 2.5V minimum supply voltage constraint. Consider the 16-byte page write buffer size when designing software to optimize write performance and prevent page boundary overwrites.

Memory IC Part Context

This component belongs to the 24XX16 series of 16-Kbit serial EEPROMs manufactured by Microchip Technology. The series includes variants like the 24AA16 and 24FC16, which differ primarily in operating voltage ranges and maximum clock frequencies. The 24LC16B specifically targets standard 2.5V to 5.5V logic systems.

Memory IC Replacement Considerations

Direct substitutes include other packages of the same electrical specification, such as 24LC16B-I/SN or 24LC16B-E/SN. Cross-family replacements like the 24AA16 require verification of the lower 1.7V operating capability.
