Description and Introduction

Quad Serial UART with 128-Word FIFOs The MAX14830ETM+ is a quad universal asynchronous receiver-transmitter (UART) manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX14830ETM+  
- **Package:** 48-TQFP (7x7mm)  
- **Operating Voltage:** 1.62V to 3.63V  
- **Data Rate:** Up to 3Mbps per UART  
- **Number of UART Channels:** 4  
- **Interface:** SPI (up to 26MHz) or I²C (up to 3.4MHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **FIFO Depth:** 128 bytes (per transmitter and receiver)  
- **Additional Features:**  
  - Hardware/software flow control  
  - Programmable baud rate  
  - Auto RS-485 half-duplex direction control  
  - 9-bit multidrop mode  

### **Descriptions:**  
The MAX14830ETM+ is a quad UART with advanced features designed for industrial, embedded, and communication applications. It supports four full-duplex UART channels with independent configurations, making it suitable for systems requiring multiple serial ports. The device can be controlled via SPI or I²C, reducing GPIO usage.  

### **Features:**  
- Four independent UART channels in a single chip.  
- Supports standard UART protocols (5-9 data bits, parity, stop bits).  
- 128-byte FIFOs for both transmit and receive (per UART).  
- Auto hardware/software flow control (RTS/CTS, XON/XOFF).  
- RS-485 half-duplex direction control with automatic switching.  
- Low-power operation (1.62V to 3.63V supply range).  
- Industrial temperature range (-40°C to +85°C).  
- Configurable interrupt outputs.  

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