24AA16T-I/CS16K

Memory IC Overview

The Microchip Technology 24AA16T-I/CS16K 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 clock frequencies up to 400 kHz at voltages between 2.5V and 5.5V, and 100 kHz when operating below 2.5V. The device utilizes low-power CMOS technology, drawing a maximum standby current of 1 μA and an active read current of 1 mA. It includes hardware write protection via the WP pin and supports page writes of up to 16 bytes within a 5 ms cycle time.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication using I²C-compatible protocols for efficient data transfer.
• Includes a 16-byte page write buffer to optimize write operations and reduce internal programming cycles.
• Features Schmitt trigger inputs and noise suppression circuits to ensure reliable operation on electrically noisy buses.
• Provides hardware write protection capability through the dedicated WP pin to secure memory arrays.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Data acquisition systems needing persistent logging of sensor readings
• Personal communications devices utilizing low-power memory solutions

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm compliance with RoHS directives and check for any relevant automotive qualification status if applicable to the target environment. Ensure availability aligns with project timelines as supply conditions may vary.

Memory IC Selection Notes

Select this component for applications requiring small form factor memory with I²C connectivity. Consider the voltage range requirements carefully, as clock frequency compatibility depends on the supply voltage level. Evaluate the need for hardware write protection and page write capabilities against system software constraints.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC16B and 24FC16 models but differs in voltage ranges and maximum clock speeds. The device is designed for advanced low-power applications across industrial and extended temperature ranges.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24XX16 family such as the 24LC16B or 24FC16, provided voltage and speed requirements are met. Verify pinout compatibility and electrical characteristics before substitution.
