24LC16B/SN

Memory IC Overview

The Microchip Technology 24LC16B/SN is a 16 Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols, supporting a maximum clock frequency of 400 kHz for VCC ranges between 2.5V and 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature grades from -40°C to +85°C. Key electrical characteristics include a maximum access time of 900 ns, a page write time of 5 ms maximum, and standby current of 1 μA maximum.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 2.5V with minimal active and standby currents.
• Two-wire serial interface compatible with I²C protocols, featuring Schmitt trigger inputs for noise suppression.
• Hardware write-protect capability via the WP pin to inhibit write operations when tied to VCC.
• Self-timed erase/write cycles with a 16-byte page write buffer for efficient data handling.

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters.
• Industrial control applications needing reliable memory in noisy environments.
• Consumer electronics utilizing low-voltage power supplies.
• Automotive components requiring AEC-Q100 qualified memory solutions.

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-lead SOIC package type during procurement. Confirm that the Industrial temperature grade (I) meets the operational requirements of the target environment. Ensure compatibility with the system's I²C bus voltage levels, as this device requires a minimum of 2.5V. Check for RoHS compliance status if required by manufacturing standards.

Memory IC Selection Notes

Select the 24LC16B/SN when a 16 Kbit capacity with an I²C interface is required for 2.5V to 5.5V systems. Choose this part over the 24AA16 variant if the application cannot support voltages below 2.5V. Consider the 8-lead SOIC package for surface mount assembly needs. Evaluate the need for hardware write protection if data integrity against accidental writes is critical.

Memory IC Part Context

This component belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16 and 24FC16 devices but differs in operating voltage and clock speed specifications. The 24LC16B series is specifically optimized for standard 2.5V to 5.5V logic levels, distinguishing it from lower-voltage or higher-speed counterparts within the same product line.

Memory IC Replacement Considerations

The 24LC16BT-I/SN serves as a tape-and-reel version of this component. Verify package dimensions and marking codes when substituting with other 8-lead SOIC EEPROMs from different manufacturers to ensure mechanical fit.
