24LC16BT-H/OT16KVAO

Memory IC Overview

The Microchip Technology 24LC16BT-H/OT16KVAO is a 16-Kbit Electrically Erasable PROM (EEPROM) organized as eight blocks of 256 x 8-bit memory. It features a two-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz and an access time of 900 ns. The device operates on a single supply voltage ranging from 2.5V to 5.5V. It supports hardware write protection via the WP pin and includes Schmitt trigger inputs for noise suppression. The component is qualified under AEC-Q100 standards and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• AEC-Q100 automotive qualification for high reliability
• Extended temperature range operation up to +150°C
• Hardware write-protect capability via dedicated pin
• Self-timed erase/write cycle with page write buffer

Memory IC Applications

• Automotive embedded systems requiring high-temperature endurance
• Industrial control units needing reliable non-volatile data storage
• Consumer electronics utilizing I2C communication protocols

Memory IC Procurement Notes

Verify the specific suffix 'H' confirms the high-temperature grade (-40°C to +150°C) and 'OT' indicates the SOT-23 package variant. Confirm '16KVAO' denotes Automotive Grade qualification. Ensure the ordering code matches the required package type and temperature range specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when application environments exceed standard industrial temperatures, requiring operation up to +150°C. The AEC-Q100 qualification makes it suitable for automotive applications where reliability is critical. Choose the SOT-23 package for space-constrained designs or SOIC for general-purpose surface mount needs.

Memory IC Part Context

This part belongs to the 24LC16B family of 16-Kbit I2C Serial EEPROMs. It shares core functionality with standard industrial variants but is distinguished by its extended high-temperature rating and automotive qualification. The 'H' suffix specifically denotes the high-temperature performance tier within the product line.

Memory IC Replacement Considerations

Standard 24LC16B-I/SN or -I/ST variants serve as functional substitutes but lack the extended +150°C temperature rating and AEC-Q100 automotive qualification. Verify that the replacement meets the specific thermal and reliability requirements of the target application.
