Overview
AVAILABLE MAX3100 SPI/MICROWIRE-Compatible UART in QSOP-16 General Description 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 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 baudrate 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.
