24LC16BH-E/MS

Memory IC Overview

The Microchip Technology 24LC16BH-E/MS is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features low-power CMOS technology, drawing a maximum read current of 1 mA and standby current of 5 μA at extended temperatures. It supports I²C compatible two-wire serial interface with Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Self-timed erase/write cycle with a page write buffer supporting up to 16 bytes
• High reliability with over one million erase/write cycles and data retention exceeding 200 years
• Robust ESD protection rated greater than 4,000V on all pins

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in sensor interfaces
• Device identification and parameter storage in automotive electronics

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the MSOP package type and Extended temperature grade (-40°C to +125°C). Confirm the specific part number matches the 24LC16BH variant requiring a minimum 2.5V supply voltage. Ensure compliance with RoHS standards and AEC-Q100 qualification requirements if intended for automotive applications. Cross-reference the datasheet revision DS20002118B for accurate electrical specifications.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with hardware write protection is required. The 24LC16BH variant is suitable for systems operating at or above 2.5V, distinguishing it from lower-voltage counterparts like the 24AA16H. The MSOP package offers a compact footprint for space-constrained designs. Verify that the application environment falls within the extended temperature range capabilities specified for the 'E' suffix.

Memory IC Part Context

This device belongs to the 24XX16H family of 16-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA16H and 24FC16H, which differ primarily in supply voltage ranges and maximum clock frequencies. The 24LC16BH specifically targets applications requiring operation down to 2.5V with 400 kHz I²C compatibility, offering a balance of performance and power efficiency for standard logic levels.

Memory IC Replacement Considerations

Direct substitutes include other members of the 24XX16H family, such as the 24AA16H or 24FC16H, provided their voltage and speed specifications align with the system design. Ensure that any replacement maintains the same package type (MSOP) and temperature rating (Extended) to guarantee physical and environmental compatibility without circuit modification.
