General Description
The MAX3100 universal asynchronous receiver transmit-
ter (UART) is the first UART specifically optimized for
small microcontroller-based systems. Using an
SPI/Microwire interface for communication with the
host microcontroller (C), the MAX3100 comes in a com-
pact 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 quies-
cent current to 10A, 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-handshak-
ing 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.
