MAX3107 Overview

SPI/I2C UART with 128-Word FIFOs and Internal Oscillator

EVALUATION KIT AVAILABLE
MAX3107
SPI/I
2
C UART with 128-Word FIFOs
General Description
The MAX3107 is an advanced universal asynchronous
receiver-transmitter (UART) with 128 words each of
receive and transmit first-in/first-out (FIFO) that can be
controlled through I
2
C or high-speed SPI. The 2x and
4x rate modes allow a maximum of 24Mbps data rates.
A phase-locked loop (PLL), prescaler, and fractional
baud-rate generator allow for high-resolution baud-rate
programming and minimize the dependency of baud rate
on reference clock frequency.
Autosleep and shutdown modes help reduce power con-
sumption during periods of inactivity. A low 640µA (typ)
supply current and tiny 24-pin TQFN (3.5mm x 3.5mm)
package make the MAX3107 ideal for low-power portable
devices.
Integrated logic-level translation on the controller and
transceiver (RX/TX and
RTS/CTS)
interfaces enable use
with a wide selection of RS-232/RS-485 transceivers.
Automatic hardware and software flow control with select-
able FIFO interrupt triggering offloads low-level activity
from the host controller. Automatic half-duplex transceiver
control with programmable setup and hold times allow
the MAX3107 to be used in high-speed applications, for
example Profibus-DP.
The MAX3107 is ideal for use in portable devices,
industrial, and automotive applications. The MAX3107 is
available in a 24-pin SSOP package and a 24-pin TQFN
package. It is specified over the -40°C to +85°C extended
ambient temperature range.
