Description and Introduction

SPI/I²C UART with 128-Word FIFOs The MAX3107ETG+ is a UART (Universal Asynchronous Receiver/Transmitter) IC manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX3107ETG+  
- **Type:** UART with SPI Interface  
- **Package:** 24-TQFN (4x4)  
- **Operating Voltage:** 2.35V to 3.6V  
- **Data Rate:** Up to 230kbps  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Number of Channels:** 1  
- **Operating Temperature Range:** -40°C to +85°C  
- **FIFO Buffers:** 128-byte TX, 128-byte RX  
- **Additional Features:**  
  - Automatic hardware and software flow control  
  - Programmable baud rate generator  
  - Low-power sleep mode  

### **Descriptions:**
The MAX3107ETG+ is a highly integrated UART with an SPI interface, designed for low-power embedded applications. It simplifies serial communication by converting SPI data to UART signals and vice versa. The device includes FIFO buffers to reduce CPU overhead and supports automatic hardware/software flow control for reliable data transmission.

### **Features:**
- **SPI-Compatible Interface** – Enables easy integration with microcontrollers.  
- **Low Power Consumption** – Suitable for battery-powered applications.  
- **128-Byte FIFOs** – Reduces CPU load by buffering data.  
- **Auto Flow Control** – Supports RTS/CTS and XON/XOFF protocols.  
- **Programmable Baud Rate** – Adjustable up to 230kbps.  
- **Industrial Temperature Range** – Operates from -40°C to +85°C.  
- **Compact 24-TQFN Package** – Space-saving design for compact PCBs.  

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

Application Scenarios & Design Considerations

SPI/I²C UART with 128-Word FIFOs

Alternative Part Number

  • XR21V1410IL16-F --: Single-channel USB-to-UART bridge in a 16-pin QFN, functionally similar to the MAX3107 and widely used as a drop-in style alternative.
  • CP2102N-A02-GQFN24 --: USB-to-UART bridge with integrated transceiver and configurable GPIO, offering comparable UART bridging functionality with easy availability.
  • FT234XD-R --: Compact USB-to-serial UART interface IC with proven driver support, suitable as a functional replacement for USB-UART bridging applications.
  • SC16IS752IPW --: Dual UART with I2C/SPI interface in TSSOP-28, functionally similar to the MAX3107 single UART with I2C/SPI, widely available and well documented.
  • XR20M1172IL32 --: Dual-channel UART with SPI/I2C interface in a comparable small package, offers similar bridging functionality and is a common alternative for SPI/I2C UART applications.
  • TL16C752DIPF --: Dual UART with 64-byte FIFO in TQFP-48, provides similar serial-to-parallel bridging capability and is a mature, broadly sourced alternative.
