Description and Introduction

24-bit Enhanced port expander with Keypad and PWM controller Xpander logic The **STMPE2401TBR** is a **GPIO expander** manufactured by **STMicroelectronics**. Below are its key specifications, descriptions, and features based on the available knowledge:

### **Specifications:**
- **Interface:** **I²C** (up to 400 kHz)
- **Number of GPIOs:** **24** (configurable as input/output)
- **Operating Voltage:** **1.8V to 5.5V**
- **Current Consumption:** Low power consumption (typ. **10 µA** in standby mode)
- **Interrupt Support:** Configurable interrupt output
- **Package:** **TSSOP-28**
- **Operating Temperature Range:** **-40°C to +85°C**

### **Descriptions:**
- The STMPE2401TBR is a **24-bit GPIO expander** designed to provide additional I/O ports via the I²C bus.
- It is commonly used in applications requiring **extra GPIOs** where the host microcontroller has limited pins.
- Supports **interrupt functionality** to notify the host of input changes.

### **Features:**
- **24 configurable GPIO pins** (input/output with pull-up/pull-down resistors)
- **I²C-compatible interface** (supports standard and fast modes)
- **Low standby current** (suitable for battery-powered applications)
- **Programmable interrupt generation** (for efficient event handling)
- **Wide voltage range** (compatible with 1.8V, 3.3V, and 5V systems)
- **Schmitt trigger inputs** for noise immunity
- **ESD protection** (enhanced robustness)

This information is strictly based on the manufacturer's datasheet and technical documentation.
