24LC16B-E/P

Memory IC Overview

The Microchip Technology 24LC16B-E/P is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a two-wire I²C compatible serial interface. The device features an access time of 900 ns, a page write buffer for up to 16 bytes, and hardware write protection. It is housed in an 8-lead PDIP package and rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication using the I²C protocol
• Includes hardware write protection controlled by the WP pin
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides high reliability with over one million erase/write cycles and data retention exceeding 200 years

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control units needing reliable parameter logging
• Consumer electronics utilizing low-power memory solutions
• Automotive modules requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) and 'P' indicates the 8-lead PDIP package. Confirm the specific voltage requirements align with the 2.5V minimum specification for the 24LC16B series. Ensure compatibility with the host system's I²C bus timing constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when an extended temperature range is required alongside standard I²C connectivity. The 24LC16B variant specifically requires a minimum supply voltage of 2.5V, distinguishing it from lower-voltage alternatives like the 24AA16. The PDIP package is suitable for through-hole mounting applications where mechanical robustness is prioritized over board space efficiency.

Memory IC Part Context

This part belongs to the Microchip 24XX16 family of serial EEPROMs, which includes the 24AA16 and 24FC16 variants. While sharing the same memory architecture and interface, the 24LC16B is distinguished by its 2.5V minimum operating voltage and 400 kHz maximum clock speed. The family offers various package options including SOIC, TSSOP, and DFN, but the 'P' suffix specifically denotes the PDIP configuration.

Memory IC Replacement Considerations

Direct substitutes within the same package and electrical specifications include the 24LC16B-I/P for industrial temperature ranges. Cross-family replacements such as the 24AA16 or 24FC16 require verification of voltage level compatibility and clock frequency limits.
