Description and Introduction

SPI/Microwire-Compatible UART in QSOP-16 The MAX3100CEE is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX3100CEE  
- **Package:** 16-QSOP (Quarter-Small Outline Package)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Data Rate:** Up to 230kbps  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Operating Temperature Range:** -40°C to +85°C  
- **FIFO Buffers:** 8-word deep receive and transmit FIFOs  
- **Crystal Oscillator Input:** Supports external crystals or clock input  
- **Interrupt Output:** Configurable for various UART events  
- **Auto-Shutdown/Low-Power Modes:** Yes  

### **Descriptions:**
The MAX3100CEE is a serial UART with an SPI interface, designed to provide microcontroller-based systems with asynchronous serial communication capabilities. It integrates a full-duplex UART, FIFO buffers, and an SPI-compatible interface, reducing the need for external components. It operates over a wide voltage range, making it suitable for both 3.3V and 5V systems.

### **Features:**
- **SPI-Compatible Interface:** Allows easy connection to microcontrollers.  
- **Low Power Consumption:** Supports auto-shutdown and wake-up modes.  
- **Programmable Baud Rate:** Up to 230kbps.  
- **Hardware and Software Flow Control:** Supports RTS/CTS handshaking.  
- **8-Word FIFOs:** Reduces CPU overhead for data handling.  
- **Interrupt Output:** Configurable for TX empty, RX full, and other events.  
- **Wide Supply Voltage Range:** 2.7V to 5.5V operation.  
- **Industrial Temperature Range:** -40°C to +85°C.  

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

Application Scenarios & Design Considerations

SPI/Microwire-Compatible UART in QSOP-16

Alternative Part Number

  • SPI-3100-UART --: Pin-compatible UART-to-SPI bridge with similar register set and 16-pin QSOP package, suitable as a direct functional drop-in.
  • SC16IS750IBS --: Widely available SPI-to-UART bridge with comparable baud rates and FIFO depth, though it requires minor firmware register remapping.
  • XR20M1172 --: SPI/I2C UART bridge offering similar functionality and package options, usable as a fallback with moderate software changes.
  • SPI-UART bridge equivalent: SC16IS750IBS --: SPI-to-UART bridge with similar function and small package, widely available and often used as a MAX3100 substitute.
  • ST16C2550 --: Dual UART with SPI-like interfacing options in some variants; a common alternative family for UART expansion when the MAX3100 is unavailable.
  • SPI-3100 compatible: MCP2120 --: UART-to-SPI/IrDA bridge with similar function; different series and vendor, commonly used as a functional substitute for MAX3100 in SPI UART applications.
  • SC16IS750 --: I2C/SPI-to-UART bridge offering comparable UART expansion functionality; different naming and manufacturer, suitable when SPI UART bridging is needed.
