USB Ethernet Bridges with I2C Master, UARTs, GPIOs
MaxLinear USB Ethernet bridges add Ethernet connectivity to any system with an
available USB port. Designed for embedded and industrial applications where space
is at a premium, MaxLinear’s USB Ethernet bridges pack the most functionality in
the smallest package. The XR22800 and XR22801 USB Ethernet devices, which
integrate an I2C master and multiple GPIOs, are delivered in a 5mm by 5mm QFN
package. Even the XR22804, which bridges USB to Ethernet and integrates four
UARTs, an I2C master and 32 GPIOs, is delivered in a compact 8mm by 8mm
footprint. Other devices in similar package sizes only offer USB to Ethernet.
All of MaxLinear’s USB Ethernet products are designed for reliability in consumer
and industrial environments and provide the industry’s highest level of ESD
protection at ±15kV HBM.
Development is simple with MaxLinear’s USB bridging products. The devices work
with standard software drivers in Windows, Linux, Android and Mac OS X. For those
designers who need to get to market quickly, enhanced features such as RS-485
Half-Duplex Control and 9-bit or Multidrop Mode can be enabled in MaxLinear’s USB
bridges to simplify software and hardware development. Custom software drivers
and applications are also available or for those instances where a standard driver is
not available or where unique functionality is required. For example, the UART ports
are easily configured for any non-standard baud rate over 300 bps and the GPIOs
are readily tailored for enhanced functionality. All of MaxLinear’s custom Windows
drivers are certified to the Microsoft WHQL/HCK standard to ensure compatibility
and reliable performance.

The LPC bus, which replaced the ISA bus is a local bus found on system boards
that connects to serial ports and other peripheral devices. MaxLinear offers
2-channel and 4-channel LPC UARTs that are I/O mapped to traditional
COM port addresses of 0x3F8, 0x2F8, 0x3E8 and 0x2E8 by default. If those
addresses are not available, the BIOS can program other I/O addresses in the
base address registers at boot-up. The UARTs in the XR28V38x are software
compatible with the industry-standard 16550 and can use the standard serial
port drivers found in almost all operating systems.

MaxLinear’s 8-bit UARTs are the industry’s largest UART product family
offering devices from 1 to 8 channels and FIFO sizes up to 128 Bytes. Each
UART has a parallel 8-bit bus interface. The UART offloads the serialization
and de-serialization of the data from the MCU or processor. The enhanced
features simplify hardware design and software development. The “Intel”
interface has separate address, data, read and write lines. The “Motorola”
interface has separate address and data lines, but the read/write lines are
shared. The “VLIO” interface has separate read and write lines, but the
address and data lines are multiplexed. Almost all of the 8-bit UARTs are
compatible with the industry-standard 16550 UARTs, hence, they can use
the standard serial port drivers in almost all operating systems.

8-Bit UARTs
11
The 2-channel 8-bit UART family integrates 2 UARTs into a single package and further
simplifies the hardware design by eliminating redundant external components. In the “Intel”
mode, there is a chip select and interrupt pin per channel. In the “Motorola” mode, there is
only 1 chip select and 1 interrupt pin.
Most UARTs in this family are software compatible with the industry-standard 16550
UART, so they can be used with the standard serial port drivers in most operating systems.
Some products in this family also have a parallel port (ST16C452/ 452PS/552/552A).
The parallel ports will work with standard parallel port drivers.

The 4-channel and 8-channel product families integrate 4 and 8 UARTs into
a single package. In addition, the XR16L784 and XR16xx98 families also
support a single chip select and single interrupt pin in both the “Intel” and
“Motorola” mode to simplify the hardware design. These devices also have a
global interrupt status register so the software can quickly determine which
UART generated the interrupt without having to check the status of all of the
individual UART channels.
Almost all of these UARTs are based on the industry-standard 16550 UART,
and are therefore compatible with standard serial port drivers. However, some
driver customization may be required. Assistance for customizing software
drivers is available from MaxLinear’s UART technical support team.

MaxLinear has a diverse portfolio of RS-485/RS-422 serial transceivers with wide
supply voltage operation between 2.8V to 5.5V. Products range from industry-standard
transceivers to ultra-high speed, 52Mbps and high differential output transceivers. In
addition, MaxLinear has RS-485/RS-422 transceivers that are compliant with popular field
buses including PROFIBUS. Advanced features, like hot swap, enhanced fail safe and 15kV
ESD protection, ensure reliable and robust data communication over long cable lengths.
Several transceivers feature a low voltage logic interface pin that allows system designers
to interface directly with 1.8V devices without the need for external components, saving
design time and board space.
The XR33x5x family of high performance RS-485/RS-422 transceivers are designed for
improved performance in noisy industrial environments and increase tolerance to system
faults. The analog bus pins can withstand direct shorts up to ±60V and are protected
against ESD events up to ±15kV HBM. Multipoint applications over long cable runs will
benefit from the extended ±25V common mode voltage range of these transceivers.

MaxLinear offers a large portfolio of RS-232 serial transceivers. The family
consists of traditional RS-232 transceivers to the more advanced RS-232
transceivers with Auto On-line Plus and low voltage logic (1.65V to 5.5V I/O
logic supply) features. In addition, many of the RS-232 transceivers have
enhanced ESD protection. MaxLinear offers new RS-232 products that meet
rigid IEC 61000-4-2 air-gap and contact ESD standards. This protection makes
the product immune to damage from ESD strikes. Many of the devices are
drop-in replacements and functional equivalents to existing industry- standard
solutions.
