The MAX3100 universal asynchronous receiver transmitter (UART) is the first UART specifically optimized for small microcontroller-based systems. Using an SPI™/MICROWIRE™ interface for communication with the host microcontroller (µC), the MAX3100 comes in a compact 24-pin-TQFN and 16-pin QSOP. The asynchronous I/O is suitable for use in RS-232, RS-485, IR, and opto-isolated data links. IR-link communication is easy with the MAX3100's infrared data association (IrDA) timing mode.

The MAX3100 includes a crystal oscillator and a baud-rate generator with software-programmable divider ratios for all common baud rates from 300 baud to 230k baud. A software- or hardware-invoked shutdown lowers quiescent current to 10µA, while allowing the MAX3100 to detect receiver activity.

An 8-word-deep first-in/first-out (FIFO) buffer minimizes processor overhead. This device also includes a flexible interrupt with four maskable sources, including address recognition on 9-bit networks. Two hardware-handshaking control lines are included (one input and one output).

The MAX3100 is available in 14-pin plastic DIP and small, 16-pin QSOP packages in the commercial and extended temperature ranges.

Product Detail

The MAX3100 evaluation kit (EV kit) provides a proven design to evaluate the MAX3100 SPI™/MICROWIRE™-compatible universal asynchronous receiver transmitter (UART). The EV kit also includes Windows 2000/XP/Vista®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX3100.

The MAX3100 uses the SPI/MICROWIRE interface for communication with the on-board MAXQ2000 microcontroller (µC). The on-board DIP switches and momentary pushbutton switches are used to configure the MAX3100 internal registers.

The EV kit can be connected to a PC serial port directly or through a straight-through extension cable. The PC is a data terminal equipment (DTE) device and the EV kit is a data communications equipment (DCE) device.

After the EV kit and the PC serial port are configured properly, the PC can send characters to the MAX3100. The on-board MAXQ2000 µC reads the received data from the MAX3100 and displays the characters on the on-board seven-segment LED or sends back data to the PC.

Other switches, jumpers, and pads are provided to modify the board to the numerous configurations available for the MAX3100.
