SPI/MICROWIRE-Compatible Universal Asynchronous Transceiver UART in QSOP-16 IC MAX3100EEE+T

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 (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 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 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-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.
