Description and Introduction

5V, Step-Down, Current-Mode PWM DC-DC Converters The MAX730ACPA is a serial interface peripheral manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Maxim Integrated (Analog Devices)  

### **Part Number:**  
MAX730ACPA  

### **Description:**  
The MAX730ACPA is a serial-interfaced peripheral designed for microcontrollers. It provides I/O expansion with 20 I/O ports, configurable as inputs or outputs. It operates with a simple 4-wire serial interface and is suitable for applications requiring additional I/O lines.  

### **Key Features:**  
- **I/O Ports:** 20 bidirectional I/O pins (configurable as inputs or outputs)  
- **Interface:** 4-wire serial interface (SPI™/QSPI™/MICROWIRE™ compatible)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Low Power Consumption:**  
  - 150µA (active mode)  
  - 1µA (shutdown mode)  
- **High Output Drive:** ±20mA sink/source per I/O pin  
- **Package:** 20-pin PDIP (Plastic Dual In-line Package)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Built-in Power-On Reset:** Ensures predictable startup conditions  
- **Schmitt-Trigger Inputs:** For noise immunity  

### **Applications:**  
- Microcontroller I/O expansion  
- Industrial control systems  
- Keypad interfaces  
- LED displays  
- General-purpose digital I/O expansion
