Description and Introduction

2048 x 8-bit CMOS EEPROM with I2C-bus interface The **PCF85116-3** is a versatile integrated circuit (IC) designed for low-power, high-performance applications in embedded systems. As part of the PCF85xxx family, this component is widely recognized for its efficiency in managing input/output (I/O) expansion and interfacing with microcontrollers.  

Featuring an **I²C-bus interface**, the PCF85116-3 simplifies system design by enabling communication with minimal wiring. It supports **16 quasi-bidirectional I/O pins**, allowing flexible configuration for various digital signals. The device operates at a **wide voltage range (2.3V to 5.5V)**, making it suitable for both battery-powered and standard logic-level applications.  

Key characteristics include **low standby current consumption**, ensuring energy efficiency in power-sensitive designs. Additionally, its **interrupt output** capability enhances responsiveness in event-driven systems. The PCF85116-3 is commonly used in industrial controls, consumer electronics, and automation systems where reliable I/O expansion is essential.  

With its compact footprint and robust performance, this IC provides a cost-effective solution for designers seeking to extend microcontroller functionality without added complexity. Its compatibility with standard I²C protocols ensures seamless integration into existing architectures, reinforcing its utility across diverse electronic applications.
