Texas Instruments 1Q 2007
XIO2200 PCI Express-to-1394b Chip
The XIO2200 is a single-function PCI
Express-to-PCI translation bridge where
the PCI bus interface is internally connected
to a 1394a Open-Host Controller
Link-Layer controller with a two-port
1394a PHY. The device is capable of
transferring data between the PCI
Express bus and the 1394 bus at 100, 200
and 400 Mbps. The XIO2200 provides
two 1394 ports that have separate cable
bias (TPBIAS). The device also supports
the IEEE Std. 1394a-2000 power-down
features for battery-operated applications
and arbitration enhancements.
TUSB3410 USB-to-Serial Bridge
The TUSB3410 provides an easy way to
move a serial-based legacy device to a
fast, flexible USB interface by bridging
between a USB port and an enhanced
UART serial port. The TUSB3410 contains
all the necessary logic to communicate
with the host computer using the USB
bus.
Key Features
• USB full-speed-compliant: data rate of
12 Mbps
• 8052 microcontroller with 16 Kbytes of
RAM that can be loaded from the host
or from external onboard memory via
an I 2 C bus
Key Benefits
• One-chip solution for 1394a
ExpressCards
• Advanced power-management features
• Software-programmable and hardware-autonomous
power-management
features for lower-power applications
such as ExpressCard
• Compact footprint, 176-ball MicroStar
BGA
• EEPROM configuration support to load
the global unique ID for the 1394
fabric
TUSB6250 Low-Power USB 2.0-to-ATA Bridge Solution
The TUSB6250 bridge for USB 2.0-compliant
PC peripheral storage products provides
world-class throughput, enhancing
the read/write performance of high-density
storage media. A highly programmable
and configurable architecture allows
you to make use of a wide variety of offthe-shelf
ATA/ATAPI devices. Industryleading
low power consumption — just
80 mA at 3.3 V — makes cable-powered
drives a reality. For self-powered drives,
the TUSB6250’s low power consumption
provides sufficient leftover power to
• Integrated, enhanced UART features
including:
• Programmable software/hardware
flow control
• Automatic RS-485 bus transceiver
control, with and without echo
• Software-selectable baud rate from
50 to 921.6 kbaud
• Built-in, two-channel DMA controller
for USB/UART bulk I/O
• Evaluation module to jump-start USB
development or for use as a complete
USB-to-RS-232 converter
recharge an onboard battery. Applications
include hard disk drives (HDDs) as well
as PC peripherals that use HDDs as their
storage media (e.g., digital audio players
and personal video recorders).
Key Features
• Low active power: 80 mA at 3.3 V (typ)
• Ultra-low standby power: 200 µA at
3.3 V
• Single 3.3-V supply operation with
integrated 1.8-V regulator
