Description and Introduction

16-bit enhanced port expander with keypad and PWM controller Xpander Logic The STMPE1601TBR is a general-purpose I/O expander manufactured by STMicroelectronics (STM). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Interface:** I²C (up to 400 kHz)  
- **Operating Voltage:** 1.65V to 3.6V  
- **Number of I/Os:** 16 (individually configurable as input or output)  
- **Interrupt Output:** Configurable interrupt pin for event detection  
- **Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-28  

### **Descriptions:**  
- The STMPE1601TBR is designed to expand the number of GPIOs available to microcontrollers via the I²C bus.  
- It features 16 I/O pins, each configurable with internal pull-up/pull-down resistors.  
- Includes an interrupt generation mechanism to alert the host controller of input changes.  

### **Features:**  
- **16 Configurable GPIOs:** Each pin can be set as input or output.  
- **Internal Pull-up/Pull-down Resistors:** Programmable for each I/O.  
- **Interrupt Capability:** Pin-change detection triggers an interrupt.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **I²C Address Selection:** Configurable via hardware pins for multiple devices on the same bus.  
- **Reset Function:** Hardware reset pin for initialization.  

This device is commonly used in applications requiring additional I/Os, such as industrial control, consumer electronics, and embedded systems.
