24AA16-I/W16K

Memory IC Overview

The Microchip Technology 24AA16-I/W16K 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 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device features low-power CMOS technology, drawing a maximum active current of 1 mA and standby current of 1 μA at industrial temperatures. It supports I²C compatible two-wire serial interface, includes hardware write-protect functionality, and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol compatible with standard I²C bus specifications.
• Includes a 16-byte page write buffer to optimize data transfer efficiency during write operations.
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides hardware write protection via the WP pin to inhibit array modifications when tied to VCC.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded devices needing secure configuration parameter retention

Memory IC Procurement Notes

Verify the specific package variant against the datasheet, as the 'W16K' suffix indicates wafer form factor availability which differs from standard tape-and-reel or tube packaging. Confirm that the Industrial temperature grade (-40°C to +85°C) aligns with your operational environment requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component for applications requiring robust noise immunity and low standby power consumption. Ensure the system design accommodates the 400 kHz maximum clock speed and utilizes appropriate pull-up resistors for the SDA and SCL lines. Consider the hardware write-protect feature if data integrity against accidental modification is critical for the application.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which also includes the 24LC16B and 24FC16 variants. While sharing similar memory organization and interface protocols, the 24AA16 is distinguished by its lower minimum operating voltage of 1.7V compared to the 2.5V minimum of the 24LC16B.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC16B and 24FC16, though voltage ranges and clock speeds differ. Verify compatibility with existing circuit designs when swapping between these variants due to differences in operating voltage thresholds and maximum clock frequencies.
