Description and Introduction

2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or 28-Port I/O Expander The MAX7300ATL is a serial-interfaced peripheral designed for microprocessors, providing I/O expansion using an SPI™/QSPI™-compatible 4-wire serial interface.  

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Key Specifications:**  
- **Interface:** SPI/QSPI-compatible (4-wire)  
- **Operating Voltage:** 2.7V to 5.5V  
- **I/O Ports:** 20 (configurable as inputs or push-pull outputs)  
- **Maximum Output Current per Pin:** 25mA  
- **Maximum Standby Current:** 1µA (shutdown mode)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 36-Pin TQFN (Thin Quad Flat No-Lead)  

### **Features:**

Description and Introduction

2-Wire-Interfaced, 2.5V to 5.5V, 20-Port or 28-Port I/O Expander The MAX7300ATL is a serial-interfaced peripheral manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** I/O Expander  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Number of I/O Pins:** 20 (configurable as inputs or outputs)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-Pin TQFN (Thin Quad Flat No-Lead)  
- **Current Consumption:** Low power consumption in standby mode  

### **Descriptions:**  
The MAX7300ATL is a high-performance, SPI-compatible I/O expander designed to provide additional GPIO (General-Purpose Input/Output) ports for microcontrollers. It supports flexible configuration, allowing each pin to be individually set as an input or output.  

### **Features:**  
- **20 Programmable I/O Pins:** Each pin can be independently configured as an input or output.  
- **SPI Interface:** Supports high-speed serial communication (up to 26MHz).  
- **Wide Voltage Range:** Operates from 2.7V to 5.5V, making it compatible with various logic levels.  
- **Interrupt Output:** Provides an interrupt signal to the host microcontroller upon input changes.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  
- **Compact Package:** 40-pin TQFN for space-constrained designs.
