UART I2C/SPI 2 Click designed for bridging SPI/I2C buses to asynchronous serial standards

Bridge SPI or I2C buses to high-speed serial interfaces like RS-232, RS-485, or IrDA with MAX3109

 

UART I2C/SPI 2 Click is a compact add-on board that provides a high-performance dual UART interface for bridging SPI or I2C processor buses to asynchronous serial communication standards such as RS-232, RS-485, or IrDA. It is based on the MAX3109, a dual UART with 128-word receive and transmit FIFOs from Analog Devices.

 

KEY FEATURES:
 

  • Dual UART Bridge: Provides two independent UART channels for converting SPI or I2C bus signals to standard serial protocols
  • High Data Rate: Supports data rates up to 24Mbps
  • Large FIFOs: Features 128-word receive and transmit FIFOs per channel for efficient data handling and reduced host processor overhead
  • Flow Control: Includes automatic hardware and software flow control
  • Protocol Support: Supports programmable baud-rate generation, logic-level translation, and half-duplex transceiver control for protocols like PROFIBUS DP
  • Expansion: Features two unpopulated GPIO headers offering user-configurable I/O or interrupt functionality, along with dedicated reset and interrupt pins

 

APPLICATIONS:
 

  • Ideal for PLCs (Programmable Logic Controllers) and building automation applications requiring reliable high-speed serial connectivity (e.g., RS-485)
  • Suitable for power meters and POS (Point-of-Sale) systems to integrate high-speed serial peripherals
  • Used in handheld devices and medical systems that need to bridge a host processor's SPI/I2C to external serial communication ports
  • Any application requiring a robust solution for bridging between parallel/synchronous processor buses (SPI/I2C) and asynchronous serial standards (RS-232, RS-485, IrDA)

ABOUT CLICK BOARDS™

Click boards™ follow a modular prototyping add-on board standard invented by MIKROE, which revolutionizes the way users add new functionalities to development boards. Click boards™ enable design engineers to change peripherals easily, cutting months off development time. To enable hundreds of Click board to be connected to the microcontroller or microprocessor, we have invented the socket standard - mikroBUS™. This uniform connection interface allows you to connect any Click board to a main board instantly. The company releases a new Click board nearly every day at 10am, and many leading microcontroller companies including Microchip, NXP, Infineon, Dialog, STM, Analog Devices, Renesas, and Toshiba now include the mikroBUS™ socket on their development boards.

ABOUT MIKROE

MIKROE is committed to changing the embedded electronics industry through the use of time-saving industry-standard hardware and software solutions. With unique concepts like Remote Access, One New Product/Day, Multi-Architectural IDE and most recently, the EmbeddedWiki™ platform with more than million ready-for-use projects, MIKROE combines its dev boards, compilers, smart displays, programmers/debuggers and 1850+ Click peripheral boards to dramatically cut development time. mikroBUS™; mikroSDK™; SiBRAIN™ and DISCON™ are open standards and mikroBUS only has been adopted by over 100 leading microcontroller companies and integrated on their development boards.
