24LC16BT-E/MS

Memory IC Overview

The Microchip Technology 24LC16BT-E/MS is a 16-Kbit (2K x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology with maximum active read current of 1 mA and standby current of 5 μA at extended temperatures. It includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. The memory array is organized into eight 256-word blocks.

Memory IC Feature Summary

• Supports bidirectional data transmission over a standard two-wire serial bus using I²C protocol.
• Features hardware write protection that inhibits all write operations when the WP pin is tied to VCC.
• Includes internal address pointer for automatic incrementing during sequential reads and writes.
• Provides acknowledge polling functionality to determine when internal write cycles are complete.

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control devices needing reliable logging of operational events
• Consumer electronics utilizing low-pin-count microcontroller interfaces
• Automotive applications requiring extended temperature range operation

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and minimum supply voltage of 2.5V. Confirm the '/MS' designation corresponds to the 8-lead MSOP package. Ensure compatibility with system I²C pull-up requirements and voltage levels before integration.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required with strict voltage constraints above 2.5V. Choose the MSOP package for surface-mount applications requiring compact footprint. Consider the 24AA16 variant if operation below 2.5V is necessary, or the 24FC16 if higher speed up to 1 MHz is needed.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA16 and 24FC16 but differs in operating voltage and speed specifications. The 24LC16B series is specifically optimized for 2.5V to 5.5V applications, distinguishing it from the wider voltage range of the 24AA16.

Memory IC Replacement Considerations

Direct functional substitutes include the 24LC16B-I/MS for industrial temperature grades. For lower voltage support, the 24AA16T-E/MS may be used if voltage levels permit. Higher speed requirements can be met by the 24FC16T-E/MS.
